Reversible Hammer Crusher as coal crusher

Reversible hammer crusher is a new type coal hammer crusher. Reversible Hammer Crusher is used for crushing dry and wet crushing brittle materials with medium hardness, such as: coal, coal gangue, dolomite, limestone, gypsum, wind fossils, shale, bentonite, soft refractory etc.

In order to keep up with the pace of social development, DSMAC independently produced reversible hammer crusher for coal processing industry with the purpose of making sustainable development come true. The type of coal reversible hammer crusher is according to the hardness, moisture, size of the material, and the required output size distribution. Our company supply the customer the most suitable crushers, to meet customer requirements.

Reversible hammer crusher working principle

After entering into the reversible hammer crusher, the materials are attacked by the high speed hammers, and hit to the adjustable dental plate, to be primary crushed, the plate are located in the crusher entrance, and with super wear-resistance. Then the similar size entering into the main crushing cavity , to be secondary crushed. After secondary crushing, the material are attacked by the hammers again, regain kinetic energy, highly hit to impact liner plate( toothed). The material are crushed again and again, between the liner plate, the hammers, the material themselves. Then the fine material are discharged from discharge hole, being the final-products. The final size can be adjusted according to the space, between rotor and the liner plate.

Crusher hammers for reversible hammer crusher

The rotor of reversible hammer hammer crusher is reversible, so the utilization rate of hammer is increased. Besides, since the hammer head branded “big gold tooth” is developed by our company, it is sure that the crusher hammers in the product will adopt this kind of hammer head, so that the service life can be improved by 50-150% compared with High manganese steel hammer. Without using of sieve overcomes the problem of congestion caused by material with high humidity. Besides, it is easy to maintain because of hydraulic device.

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.
High efficient coal crusher manufacturer
After years of development, DSMAC worked out a new coal crusher – ring hammer crusher in the Chinese market, ring hammer coal crusher has been widely used. Ring hammer crusher is suitable to crush brittle, medium hard materials with little moisture (Watershed is less than 15% of the material). Many customers think it is a highly efficient coal crusher. Efficient coal crusher has been successfully applied in the world, and we look for more customers to bring a higher effect.
