Stone crushing plant layout process
Stone crusher plant can crush stones into small particles with diameter of 0-5-10-15-20-25-30- 40-63-100mm. And the final size can be reached by adjusting the Discharge gate.
1. A block of materials will be taken into Jaw crusher evenly and gradually through vibrating feeder. Jaw crusher will break the materials into small size.
2. Then belt conveyor will take these materials into cone crusher or impact crusher for the secondary crushing process.
3. If the materials are too hard and smaller size is required, VSI crusher can be used to break the materials to get smaller and cubic size.
4. During those processes, if the materials do not reach the qualified size, belt conveyor will send these materials back to the crusher to be crushed again.

how to improve coal crushing efficiency

coal crushing machine is a crucial one annulus in mine production, but some external or internal factors of the impact crusher restricts the crusher production, to solve these problems is to increase productivity. Next DSMAC there for you to explain reasons of affecting coal crushing machine efficiency:
1. Improper operation:
Due to the part of operators have a careless understanding to the working principle of crusher, and the improper operation in the daily production and cannot play crusher itself normal production performance, which affects the coal crushing machine efficiency.
2. Material hardness:
The harder is the material, the more difficult is the broken, and the more serious is the wear of equipment. The broken speed is slow, of course, the crushing capacity is small. This needs us have a moderate select on the choice of material.
3. Material humidity:
When materials have a large water content, materials will be easy to cause a conglutination in the coal crusher, also easy to cause a congestion at next conveying process, caused by broken ability reduced. To solve this problem, firstly, we should strictly control the water content of the material in the material choice. If the choiced material’s water content is too big, we can use sunshine or air drying way to reduce the percentage of water in the material.
4. The fineness of broken materials:
The higher is the demanded fineness, that is to say, the more fine is the broken material, the smaller is the crushing capacity. This aspect need to see the dressing plant specific request, if no special requirements, the general will be the fineness of materials for a system of fine then.
5. Material composition:
Before a crushing, the more is the material with fine powder, the more effect is the crushing, because these fine powder are easy to adhere to effect delivery. Therefore, to materials with a large fine powder content, we should take a screen for it. Let fine powder of the material get out from the screening as far as possible, lest affect the coal crushing machine efficiency.
6.The viscosity of materials:
The bigger is the viscosity of materials, the easier is the conglutination. Materials with a big viscosity will adhere to the crushing cavity wall. If not to clean up in time, it will seriously affect the coal crushing machine efficiency. Therefore, you must pay attention to the viscosity of materials that cannot be too big.
7. Hardware equipment:
The better is the abrasive resistance of crushing equipment’s broken pieces, the bigger is the crushing ability. About this aspect, you must be on a regular repair to broken pieces of crusher. If there is any breakage or damage, you should make a timely replacement, lest effect the normal work of the coal crushing machine.

Working Principle of Ring Hammer Crusher
Ring hammer crusher mainly makes use of the impact effect to crush materials. The crushing process is roughly like this: when the materials enter the crusher, they are crushed by the high speeding ring hammer. The crushed materials gain energy from the ring hammer, rush to the crushing board at high speed, and crashed at second time. At the same time the materials bump with each other, and are repeatedly cracked. The material smaller than the grate bar gap are discharged, while larger ones on the grate bar are impacted, grinded, squeezed again to be crashed by the hammer, at last the materials are extruded by the hammer from the gap to obtain products with the required size.
