How to configure the most reasonable and efficient stone production line?

A configuration of the success of the stone production line can help customers quickly recover the cost, a configuration of the failure of the production line will make customers to increase investment costs and even bankruptcy. Zhongxin Heavy Industry will teach you how to configure the most reasonable stone production line.

Under normal circumstances, a full set of stone production line equipment mainly includes vibrating feeder, jaw crusher, counterattack type crusher, vibrating screen, belt conveyor, centralized electronic equipment composition; for the needs of different customers for processing, but also equipped with cone crusher, dust removal equipment.

In the allocation of stone production line, to fully consider the impact of various types of crushing equipment specific factors, select the appropriate crushing equipment for different materials processing operations. Usually, broken with smaller hardness such as limestone, talc and cement a series of medium degree of hardness materials, such as brittle materials in crushing operations using jaw crusher, counterattack crusher machine, high manganese steel vulnerable parts of the structure of the crushing equipment is enough material to realize the fully broken; hardness large such as basalt, granite, to use with high iron and high abrasion wearing parts of equipment, then the stone production line to make reasonable adjustments, the cone crusher, hammer crusher for production.

In the selection of stone production line, the user first need to clear their own needs of the product quality, the need for production, specifications and uses, but also take full account of the production environment and equipment quality and a series of hardware factors, the final selection of suitable production equipment for flexible and reasonable allocation, and strive to achieve production matching, fast and efficient production line operations, to achieve the maximum economic benefits.

How to improve the production efficiency of sand production line?

  Natural sand is very good building materials, but after years of continuous mining, natural sand resources are rapidly diminishing, natural sand in some areas depleted or nearly exhausted, in some areas and river, in order to maintain the natural landscape, protecting dyke dam security, protect the ecological balance, the provisions of mining is prohibited. Because of these reasons, the cost of natural sand is getting higher and higher, while its profit is getting lower and lower, the market is getting smaller and smaller. So the mechanism sand more and more popular market, the market share is also increasing.

  With the development of science and technology, sand production equipments are: vibrating feeder, jaw crusher, sand making machine, washing sand machine and supporting the crushing equipment. The choice of a production line, mainly depend on the crusher and other equipment configuration, to form a production line of work efficiency, so the difference is the type of crusher is used for the whole production line of the decisive factor, which means that the choice of crusher, is the main reason to determine the production line.

Reducing the raw material size can improve the production efficiency, so the use of cone crusher will be a crushing material to the grinding of the material granularity, improve production efficiency. Cone crusher is used in the production line of sand and gravel, the advantages of simplifying process flow and saving production cost.

What might cause cone crusher oil leakage

Cone Crusher now has become the new darling of many mineral processing industry, with high yield and efficiency characteristics, but if you didn't pay attention to the daily operation, there will be some problems, so routine maintenance is very important. Oil spills, oil is relatively unusual rejection of a problem, the following Zhongxin briefly introduce the cause of the problem and the solution for you.

Zhongxin technical engineers think the reason it happens is that cone crusher hydraulic oil lubrication system too high, or more lubricating oil supplied, in part, lubricating oil return passage because of insufficient flow directly into the dust water, another case is because runaway phenomenon caused by the spindle lubricating oil and dust fall into the water.

Cone crusher dumped oil may be due to excessive cone crusher spindle into the spindle bush, leading to improper running clearance, due to greater friction on the shaft; perhaps because the load is too small cone crusher, cone crusher increase feeding, under load, bowl-shaped tile outer edge contact; under light load, including a bowl-shaped tile edges. Scraping bowl or tile replacement, at the same time, the spherical body may also need to re-processing.

Understanding why this happens, we can solve this problem the corresponding cone crusher routine maintenance is very important, so that it can ensure that your device routine efficient production and extend the life of the equipment.

Cone Crusher different parts have different lubrication requirements

Good lubrication can guarantee the normal life of the cone crusher, effectively reducing the friction between the parts, we need to note that the cone crusher lubrication requirements of different parts is not the same, too much or too little will affect the life of the equipment and efficiency, the following Zhongxin will give you a brief introduction of the spring cone crusher lubrication requirements.

Spring cone crusher support sleeve is generally saw type thread, and the liner was screwed into the thread by rotating around the ring to adjust the size of the mine discharge port, because of its shape thread lubrication caused more complex, so often artificial lubrication, this can effectively ensure good lubrication components.

For lubrication spring cone crusher eccentric, spherical bearings and gears, the need to use thin oil circulation lubrication way, such lubrication is sucked from the mailbox main shut-off valve to the pump through the lubricating oil in through the filter, from two a shutoff valve into the cooler to form a two-way, flow through the gap clearance bevel gear shaft and the lower portion of the eccentric bushing and the eccentric bushing cone and straight between the liner and then back to the tank.

These are technical engineers Zhongxin lubricated parts against common method proposed, if you are experiencing problems in other lubricating actual production use, you can inquire us.

The importance of cone crusher equipment in large-scale production line

In the whole crushing production line, each crusher equipment plays an important role in each device only good coordination, can really play the greatest productivity. Cone crusher plays an extremely important role in large-scale production lines.

        First, the cone crusher most prominent advantage is the high production efficiency, low energy consumption in the production process, and is applicable for crushing high-strength materials. While the crushed material was mostly flakiness, basically for the medium size. Thus, if you want the entire production line to produce better performance when conducting matching crusher equipment should be a more detailed understanding of the performance characteristics of each crusher equipment, which according to the merits of different crusher to a reasonable match, only so as to maximize the advantages of each of the crusher so that the entire production line to achieve maximum productivity.

        Combined with the performance benefits of cone crusher, we know, cone crusher is usually installed in the jaw crusher after the break as to match the two. In the current crushing production line, a broken or rough broken jaw crusher basically, this is recognized by everyone. Two are generally broken crusher or cone crusher, impact crusher compared to the material produced grain shape is good, so why use cone crusher machine? That depends on the cone crusher which has the advantage. Cone crusher is the best performance of the crusher, the crushing process, high-power low productivity, which is the biggest advantage of a cone crusher. Thus although the cone crusher produced material, usually you need to use vertical impact crusher and sand shaping shaping. But in large-scale crushing production line, can play the role of cone crusher is very large. Thus, a large-scale production lines, usually with cone crusher with jaw crusher, vertical impact crusher to produce.

        Cone crusher not only its own production capacity, and through its material handling impact crusher and then to also make the impact crusher to achieve a high performance vertical. Thus, it can be seen that the cone crusher its main market is in relatively large crushing production line. Production in these situations, cone crusher is the essential important equipment, is to enhance the capacity of the entire production line process important crusher equipment, other equipment can not be replaced.

Crusher maintenance method

Proper care and maintenance of broken equipment can improve their work efficiency, extend equipment life, then how do the crusher maintenance work? Specific maintenance is as follows:

     1. Check. Crusher in the work process, you should first do the daily work of the inspection, when the new machine into operation, the staff on duty before work on the machine must conduct a comprehensive inspection. Check the contents, including equipment motors, the fixed part of the fastening, belt drive, bearing seals. The case of electrical switches. The machine must Weekly major parts such as board hammer, impact liner, liner wear inspection. If it is found during the inspection of serious wear parts should be promptly replaced.

     2, lubrication. Constant attention and timely manner lubrication friction surface can effectively extend the life of the equipment. Used lubricating oil, should be determined according to place of use of the machine, the temperature and other conditions, may generally be calcium - sodium based lubricants, each working eight hours after filling oil to the bearing once every three months to replace lubrication fat once, apply oil change clean gasoline or kerosene carefully cleaned bearing, added grease inside the bearing 50% by volume.

     3, the adjustment. In the course of their work but also to adjust the timing to do work-related parts, regular liner gap between the rotor and the counter is adjusted, it can effectively control the discharge particle size, to provide users with qualified materials. In addition adjustment should regularly check the bottom of the inlet gap between the hammer and the plate, adjust it, should Remove the sides of the steel frame, and then out of the steel, and then transferred to the rotation.

     4, maintenance. Crusher maintenance and ultimately to the crusher maintenance and timely repair of minor faults, can reduce the rate of replacement parts. Crusher maintenance work, including minor repairs, repair and overhaul, which should be repaired in the specific operation depending on the circumstances.

Advantages of hydraulic cone crusher

Hydraulically driven cone crusher, hydraulic cone crusher is becoming, also called hydraulic crusher, mainly by the drive shaft, eccentric, hydraulic safety device, rack, adjustment ring and other components. Hydraulic cone crusher is developed on the basis of the traditional spring cone crusher on, but the performance has a greater advantage than spring cone crusher.

Comparison of hydraulic cone crusher and spring cone crusher：

1. From the analysis of the working principle of cone crusher
Working principle of hydraulic cone crusher: driven by the eccentric shaft so that the moving cone section do spin pendulum motion, so that produce periodic relative motion dynamic cone and fixed cone liner between the liner to achieve material in the crushing cavity continuously due receive squeezing and bending and breaking.
It works spring cone crusher: The motor drive bevel gear by eccentric rotation, broken cone pendulum motion for a spin. Sometimes close and sometimes broken cone away from the fixed cone, complete crushing and nesting.

2. From the structural design of the cone crusher Analysis
Hydraulic cone crusher structure: nesting population size adjustment is mainly achieved by driving the hydraulic cylinder piston. Increasing the size of the discharge opening, just control the fuel into the cylinder; decreases when the nesting population size, the need to control the hydraulic cylinder return oil.
Structure spring cone crusher: nesting population size is adjusted mainly by regulating the spring to achieve. When you need to increase the size of the discharge opening, you need to loosen the spring; when the need to reduce the size of the discharge opening, you need to tighten the spring.

Second, the advantages of hydraulic cone crusher：

1, a special type of crushing chamber, according to the laminated crushing theory in the effective crushing stage crushing chamber will form a high-density layer, to ensure that the fine particle size, grain shape is good, large output.

2, the automatic operating system, to ensure smooth operation of high efficiency equipment, such as automatic control panel, according to load conditions, automatically adjust the outlet gap, so that the device can be operated at maximum load.

3, self-discharge foreign matter, when there is a non-broken contaminant crushing cavity, the hydraulic cylinder hydraulic pressure in the accumulator becomes higher than the oil flows to the accumulator, so the broken wall fell, discharging foreign matter. Once the foreign body removed, the oil in the accumulator return hydraulic cylinder, cone crusher automatically returns to its original export clearance.

4, equal to the feeding device, to prevent liner deviation detected simultaneously feeding the material level, to ensure that material into the crushing chamber along the circumferential direction of the uniform fabric.

Sand washing machine working principle and applications

Sand washing machine is one for artificial sand and natural sand washing equipment, can be widely used in gravel pits, mining, building materials, water conservancy and hydropower, concrete mixing plant and other industries in the washing of the material, it can remove cover in sand impurities stone surface, while destruction of vapor-coated sand layer, in order to facilitate dewatering, played the role of efficient cleaning. We used sand washing machine is mainly divided into two types, namely, bucket wheel sand washing machine and spiral sand washing machine. The following article describes both to sand washing machine working principle and application ranges.

First, bucket wheel sand washing machine

1, the working principle

When the bucket wheel sand washing machine working motor through V-belt, reducer, gear reducer drive after slowly rotating impeller, sand and gravel into the wash tank has to trough, rolling driven impeller and grinding each other, covered with sand and gravel out surface impurities, while broken-coated sand vapor layer to facilitate dehydration; while adding water to form a powerful water flow, timely small proportion of impurities and foreign matter away and wash tank from the overflow outlet, complete cleaning action. Clean sand oil blade away from the last rotation of the impeller into the gravel out of the trough, complete cleaning action gravel.

2. Applications

Bucket wheel sand washing machine reasonable structure, large capacity, low power consumption, clean and high, at least in the process of sand washing sand churn rate, it can be widely used in gravel pits, mining, building materials, transportation, chemical industry, washing water conservancy and hydropower, concrete mixing stations and other industries of materials, grading and dehydration, is an excellent choice for domestic sand washing industry upgrading.

Second, the spiral sand washing machine

1, the working principle

Spiral sand washing machine working process is connected by an electric motor through reducer rotating, perforated plate from the bottom of the sedimentation tank to the wash water. Its sand washing process is divided into three parts, namely cleaning, dehydration, classification:

(1) Cleaning: gravel into the sedimentation tank by the helical blade action to make gravel tumbling and grinding each other to remove impurities on the sand covering the surface of the washing water is formed by the perforated plates rising water, the small proportion of foreign matter from the water overflow weir outside, thereby completing the cleaning action.

(2) dehydration: the proportion of larger particles sink to the bottom, the bottom side bending, the spiral blade will advance up the gravel. Because the water tank has a horizontal length exceeds the lower part of the right length, in advancing up the process, to remove excess moisture sand, prolapse of the water flowing into the sedimentation tank drains from the bottom on the other side, the upper end of the gravel from the tank bottom discharge discharge port.

(3) Classification: Classification material is not meet the standards by the fine particle overflow weir foreign achieve that control measures are: to adjust the weir height and speed adjustment screw. When cleaning equipment, first shed 4 plug, then turn on the water wash, fine particles and debris from the waste outlet from the plane.

2. Applications

Spiral sand washing machine has a simple structure, stable operation, sand washing clean, high yield notable features. It is widely used among the construction sites, gravel pits, glass, power plants, concrete prefabricated stone and electricians to other departments.

Factors that determine the yield of limestone crushing machine

Limestone crushing machine is a highly efficient, energy-saving gravel sand making equipment, in terms of investment lower than the same regulation equipment 35% -50%, the long-running maintenance costs are also lower than the average of about 35% of equipment, it is currently the world's advanced Crusher equipment. This device is particularly suitable for the production of abrasives, refractories, cement, quartz sand, grit and other hard, brittle material crushing and broken, in addition to having a unique advantage in terms of investment and operation, customers are more concerned about is whether production can as expected, this is an important source of business efficiency improvement. The following article will introduce the next determinants of limestone crushing machine production which in the end.

First, the service life of the wear part

We all know the quality of equipment wear parts directly determine productivity and yield limestone crushing machine, a device if wear parts quality is not good, the situation will cause frequent repair, replacement, resulting in lower production, while also increasing the maintenance costs. I am in the design when the limestone crushing machine, fully taking into account the importance of the wear parts of the hammer are based refining and pressure casting technology, steel is more pure, more dense matrix life than ordinary high manganese steel hammer 50-100% increase, more secure and reliable. The wear-resistant lining is is surfacing in the ordinary steel or heat-resistant steel plate, with high wear resistance, impact resistance, deformability and weldability properties, than ordinary steel increased by 15 times or more life.

Second, the characteristics of the material into the mill

Including material particle size, moisture content, temperature and humidity and other properties, each of which will directly affect the yield. With respect to the large size of the material, small particle size material to be broken more easily to a standard size, and therefore will accelerate the production efficiency; and some materials too much water will cause sticking on the produced material in the production process equipment, causing blockage In this case must be shut down to clean up, it will affect the overall yield; or material temperature and humidity and so on, as long as the material does not meet the required standards and be broken, will cause production decline for some reason.

Third, the model selection device

In the face of a large number of crushing limestone, we should choose the right type of crushing machine. Limestone crushing machine model, the price is different, we remind some of the material manufacturer, not because of the price and the choice of the wrong types of equipment, so that not only can not save investment costs, will result in lower production, you know, we have chosen the best equipment It is important to achieve high yield, thereby to increase corporate profits, rather than by saving some of the input costs to increase profits, it is recommended to listen limestone manufacturer's recommendations, to choose their own product model.

Cone crusher adjustment reasons set loose

In normal operation the cone crusher, the adjustment may occur sleeve loosening, then what causes the adjustment sleeve loose it? Here we look at the cone crusher adjustment sets loose reasons.

Parts damaged or broken：

1, most of the new cone crusher installed its locking sleeve and gap adjustment sleeve is 12.5mm, according to the adjustment ring and threaded locking ring wear, appropriate to enlarge the gap between the two, increase the locking stroke. And when the cone crusher long-term operation, thread galling may occur serious cases, undue gap locking sleeve and adjustment sleeve, causing loose adjustment sleeve.

2, cone crusher locking ring and the adjustment ring with four M27 bolt junctions, when impurities inside the device enters or feed particle size is too large, so that the cone crusher overload causing the locking bolt fracture, causing the lock failure cause of the adjustment sleeve loose.

3, cone crusher rolling acetabular wall and the wall is too thick will also make adjustments set loose, so when the broken wall wear refrain from welding methods, should replace the broken wall and rolling acetabular wall.

Improper operation
1, cone crusher largest feed particle size of 215mm, if larger than this size of input materials to the crushing cavity, it will cause the device to overload, crushing load increased, the locking force is relatively insufficient, causing loose adjustment sleeve.

2, in the feeding process cone crusher, if uneven feed hopper or crusher to the ore malposition, will lead cone crusher unilateral force is too large, leading to loosening of the adjustment sleeve.

Cone Crusher leakage reasons

In the mining machinery crushing production, good lubrication is undoubtedly necessary to ensure the normal operation of equipment condition, but leakage problem has also occurred, let's look at the cause of the oil spill cone crusher.

Sealing device failure：
In production pay attention to check the O-frame and the main frame between the drive shaft seals, nylon oil collector and slinger ring between the seal, O-shaped slinger and shaft seal between the wear ring , since these parts after prolonged use, wear and tear will be deformed, losing an effective seal desired elasticity, sealing means fail, it will cause the device to leakage problems.

Oil return pipe blockage：
The reason may also be leaking oil can not be quickly discharged from the device, especially when the oil temperature is low especially so in the production of the product should be careful to check whether there are stolen goods, check the drive shaft below the main drain hoses or pipes Is there a long drive shaft mount hole swag, swag otherwise accumulate will impede the flow of oil, causing oil leakage cone crusher.

Working Pressure inappropriate
Lubricating oil from the inlet pipe into the lower spindle lubricated friction disc friction, if the working pressure cone crusher lubrication system properly, will make the oil discharged from the shaft gap, causing lubricant leakage along the seal down the outer tube.

Parts unreasonable gap
If the host base oil pool wall and the counterweight stopper plate between the oil ring gap is too small, then the work process in the cone crusher, flung lubricant between them under tension easy to form seals. Seal under pressure push will continuously overflows from the inner wall of the dust seal along the main housing.

cone crusher liner plate manufacturing process

    Liner is the main component of cone crusher, it is also the most easy to wear parts, if liner wear seriously, it will affect the overall performance of the crushing chamber, so pay attention to the quality of liner when buy cone crusher is also critical. Here to introduce you Zhongxin liner manufacturing process.

    Firstly, select the liner material. Our cone crusher liner wear-resistant material selected high-manganese steel material, it have been tested, the initial hardness can reach around B260, it has excellent wear resistance, is very conducive to high hardness of the material processed.

    Secondly, the material handling process. In order to further improve the wear resistance of high manganese steel materials, we have also added alloying elements as usual, but if the carbon element is too high, then it will reduce wear and therefore alloying material is also very important. In the processing, it should strictly control access to the water time and temperature and other parameters, so that the indicators are in line with national requirements.

    Thirdly, the casting process strictly. This would not only check cone crusher liner process, and also checks the entire machinery technology. We all know that the wall of the cone crusher liners is thick and large, last up to 200mm, if the casting temperature can not reach it, it will make the grain high manganese steel liner is relatively large, so that the service life will be short, so we use metal-type cladding sand in the casting process, effectively reduce the pouring temperature, so that the liner grain refinement, to extend the service life of liner on purpose.

Twenty years of cone crusher production experience, so we focus on every detail of the production equipment, the quality of Zhongxin Heavy equipment is good for customers, you are welcome to inquire.

Due to geographical factors, in some areas the river can be directly used inside the river gravel or pebbles directly processed, due to the river gravel crushing process in the biggest problem is wear parts easy to wear, with river gravel stones factory project as a raw material, must Broken processes carefully studied. Thus, stone production line configuration for river gravel construction, Jiaozuo Zhongxin Heavy Machinery Co., Ltd. production line of technical experts working parties are given the following recommendations:

In the space and equipment investment and production permits, river gravel production building with stone production line configuration should be possible to use lamination equipment and multi-stage crushing scheme. Such as the use of jaw crusher and cone crusher, these two devices using laminated crushing principle, be able to maximize the reduction of the cost of wear parts wear, but also to reduce the anti-material sieved to increase the whole production line production capacity.

Jaw crusher cone crusher impact crusher
If the customer is an excellent product grain type, you can use a two-stage laminated crusher (jaw crusher + fine jaw crusher / cone crusher) and Crusher supporting the technology program. This configuration allows the primary crusher work completed by the broken pyramid, finally broken by the back-breaking conduct an integer, you can greatly reduce the formation of anti-material after the screening. If the anti-material ratio is too high a production line, will make the final crusher crushing increase excessive repetitive work, corresponding parts also makes the crusher loss is greatly increased.

Therefore, when selecting stones factory equipment and materials in accordance with the actual situation to the actual site selection, considering the stone sediment concentration and particle size, production capacity, investment cost, site size and other factors in order to achieve maximum efficiency crusher equipment, it is recommended Investors listen to recommendations by stone buildings production equipment manufacturers to select the most reasonable construction stones sets of production equipment.

The reason why cone crusher has relatively high price

The reason why cone crusher has relatively high price

Cone crusher is relatively popular in recent years, it is widely used in the production of raw materials for various industries, you can adjust the spout crushing, fine crushing and super fine crushing, while the cone crusher in production and on the cob type also has unparalleled advantages, many users are depressed for the high prices of cone crusher, why?

The main reason why cone crusher is expensive is the device itself, in order to improve the yield and the wear resistance equipment, there are higher costs for internal use wear-resistant material, which invisibly increase the cost of cone crusher; followed by the equipment used laminated crushing principle, which is different with the traditional crusher, while higher crusher for forging process requirements, in other words, a relatively large time-consuming process, it will become a cone crusher the main reason for higher prices.

But we can contrast, cone crusher has brought us a series of benefits, you do not think the price is expensive, and the first production of this section do not compare this device, this is for all to see, the new crusher is up to 1200tph, although many models exist but they all have a reasonable size, machined from 3-40mm has a corresponding models, all kinds of stone to ensure maximum requirement; followed by the low power consumption per unit of production, low wear rate, stable and reliable, regardless of repair or overhaul are very late aspect, and low maintenance costs.

Price of cone crusher is of high value for money investment a long-term considerations such equipment, it has a long service life, it is still very cost-effective overall doing, and proceeds faster, and the other crusher can not catch it, welcome to inquire us for more information about cone crusher.

Mining equipment cone crusher lubrication system how to repair

Cone crusher internal lubrication system is an important means of the device to ensure the normal operation of the lubrication system is a necessary condition for normal production equipment, let's look at the four elements cone crusher lubrication system works.

A suitable working temperature:

In the course of the cone crusher, the oil should be kept in the range of 38-55 degrees, higher than 60 degrees is not allowed at or below 16 degrees environment. In the actual production process, the available thermometer into the return oil pipe inside the channel, if more than 28 degrees is necessary to attract attention, because it may cause cone crusher bush-burning.

Second, a reasonable working pressure:

When the lubrication system working properly, the maximum working pressure of lubricating oil and cooling water are 0.18MPa. Exhaust valve lubrication system is installed in the drive shaft holder, the exhaust valve allows the same internal and external atmospheric pressure cone crusher, so you can ensure the smooth discharge lubricant.

Third, the correct choice of lubricants:

Winter sports can be lower viscosity oil, summer may be slightly higher kinematic viscosity oil.

Fourth, the fuel adjustment：

Cone crusher amount of lubricating oil is controlled by adjusting the valve lubricant station by adjusting the pressure, amount of lubricating oil into the interior of the drive shaft holder portion is observed through the oil flow indicator adjustment. It should be noted that although the oil flow indicator can be observed within the oil flow, but can not ensure that the internal cone crusher must have oil. Also we need to observe the return line back to the fuel, lubrication station appropriately adjust the pressure on the control valve to ensure proper lubrication oil return to ensure the normal operation of the lubrication system.

Crusher is the focus of mining machinery industry

   Competition between China crusher equipment industry more competitive, in many brands, types of equipment complex market environment, good branding work is extremely important. Crusher manufacturers of strength there is a big gap between the quality of chaotic continues to progress, through unremitting efforts, business development indirect impact crusher in the market prospects of the industry.

   Crusher mining machinery industry has become the focus of the device, there are advantages and disadvantages, Shanghai next to the crusher manufacturers for lifting equipment performance is also not entirely a policy, the company grow and also has some drawbacks. However, as a socially responsible crusher equipment manufacturers, to continue to grow, improve the deficiencies, in order to better the future development and lay a solid foundation. If the technology can not be raised in an innovative core technology will be hampered stumbling block ahead of us, so there were two problems, one can not meet the needs of the community; the second is a long time interval equipment replacement, will be derailed with the times ʱ??

   Crusher equipment reason to emerge, mainly because of its significant advantage in terms of energy conservation. At present, China crusher manufacturers energy saving as a rule crusher equipment development. In the energy saving type of society, the development of crusher equipment technology is the most solid backing, a conventional crusher low-tech, energy consumption during operation of the big dust is greater.

   China Jiaozuo in Henan Zhongxin Heavy Machinery Co., Ltd. and the simultaneous development of society, in the development of equipment to expand the brand's influence, continuously into the high-tech sound equipment performance, which will be the future of the cone crusher manufacturers to expand the market to pass.

Crusher mining machinery essential equipment

Our mechanical manufacturing has advantages and disadvantages, the overall size has entered the ranks of international producing countries, but the overall competitiveness and development potential still can not compete with the developed countries, the domestic high-end users and export products supporting infrastructure components mainly rely on imports, along with export trade frictions increase, is bound to be subject to foreign competitors and suppliers constraints. So broken machinery in the future the focus should be placed in the revitalization and development of basic technology and basic components up, raise the level of self-development.

When an industry or product export growth up to 40% to 70% in the case of inflation, when for some time, it will enter the high-risk trade friction, China's machinery industry is now broken in such a period. With the acceleration of world economic integration process, the traditional means of trade barriers gradually weakening or canceled, anti-dumping and technical barriers to trade more and more being used. Developed countries to use technology to protect the overall security of the country or region, protection of human, animal or plant safety, and environmental protection reasons, continue to take technical regulations, standards, certification, patents and other means to improve market technical threshold, for China to build a large number of export products trade barriers. Therefore, under the current export growth situation, we must remain sober and rational understanding, enhance international trade friction disputes prevention awareness and means. Manual handling car anti-dumping cases last year occurred in the construction machinery industry to give us a wake-up call. In international trade, crushers companies need to pay attention to and prevention as two trans including two security (ie anti-dumping, countervailing and safeguard measures and special safeguard measures), technical barriers, political, financial and appreciation of the renminbi and other risks. Market observe, more innovative design, production to improve quality, which are highly competitive in the circumstances is to be noted, Jiaozuo Xin Heavy Machinery Co., Ltd. to seize the hard work, to produce in order to remain unbeaten in the competition land.
