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.

The new cone crusher in two ways sealed bearing life and reliable operation of the machine

In an extremely rapid period of economic development, in order to better develop technology upgrading, cone crusher ongoing efforts, in order to more efficiently complete the job, continue to make efforts for further development, in production, the technology to a wider, The cone crusher technology to develop more far-reaching.
  The new cone crushing machine mainly divided into spring cone crusher and hydraulic cone crusher, spring cone crusher is also called Symons cone crusher. This series cone crusher dry oil or water in two ways sealed so dust and impurities can not enter the man-machine body, thus ensuring clean Run edible vegetable oil, extending the slide bearing, thrust ball bearing service life, making the machine reliable operation.

  The new cone crushing cone continuous rotation maneuver, crushing process and unloading process materials alternating along the work surface continuously high productivity. Material sandwiched between two cones, squeezed, bending and shear, broken more easily, power consumption is low. The new cone crushing machine Liaodu relatively uniform, cube shape, moving cone wear work surface more uniform. Cone Crusher structure introduction, cone crusher main frame structure, the horizontal axis, moving cone, balancing wheel, eccentric, the broken wall (fixed cone), the next broken wall (dynamic cone), fluid coupling, composition lubrication system, hydraulic system, control system and other parts. dynamic cone and fixed cone are upright, when moving cone swings in the vicinity of the crushing chamber discharge port, there is a gap between parallel strips of equal dynamic cone and fixed cone, the finished Liaoduo uniform. Inlet size small, it is able to handle after the first broken material.

Stone Production Line

Stone production line, also known as sand production line, stone crushing production line and the production line to see a production of construction sand, stone and special equipment. Sandy uniform particle size, high compressive strength, than natural sand, hammer crusher sand production more in line with the requirements of a high standard building sand; it is a feeder, jaw crusher, PCL break-through impact, heavy shaker and efficient wash sand, and with a belt connected to become a line. The production line uses the high-speed rotary wheel thrown stone to 76m / s line speed throws, impinging on liner wear, forming a stone at stone, stone crushing principle blacksmith. Make sure the whole process discharge smoothly, running reliable, energy efficient, saving 50% than conventional equipment.

Stone production line (sand production line) workflow:
Feeder silo → → → jaw crusher impact crusher (optional) → impact crusher vibrating screen → → → intermediate refined sand washing machine sand equipment or belt conveyor connected to the process of sand production line : silo feeder → → → ① jaw crusher impact crusher vibrating screen → → (finished stone) ② impact crusher vibrating screen → → sand washing machine → (finished sand) where you can share shaker It can also be used to separate intermediate equipment or belt conveyor to achieve different physical transmission.

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.
