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.

River pebble stone building production line how to configure the crushing plant

In recent years, all over the country are undertaking large-scale infrastructure construction, building stones, sand demand also increases, which also led to the rise of artificial sand production line. 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.
