Working Principle and Advantages of Coal Impact Crusher

Coal impact crusher is a kind of new coal crusher researched and developed according to the current situation in coal industry, which well solves blocking ills caused by high moisture content of materials.

Working principle of coal impact crusher:

1. Thecoal impact crusher adopts two-stage crushing by double rotors: two sets of rotors with mutual connections make materials crushed in fisrt stage be finely crushed by hammer head of rotor which rotates at high speed in seond stage; then materials impact each other by high-speed collision and achieve the desired effect, finally, they are discharged directly.

2. The coal impact crusher is without screen grate, avoiding high-moisture materials blocking screen: the traditional coal crushers with grate plate do not adapt to materials with moisture content higher than 8%; when moisture content is above 10%, it easily happens serious congestion and makes the hammer head stop turnning, so materials can't be discharged, seriously affecting the production.

Advantages of coal crusher:

First, coal crusher is without screen and grate bottom, so it can crush both high-moisture materials and dry materials.
Second, two-stage grinding by double rotors: after materials enterring into coal crusher, they will be crushed by two stages; materials impact each other in closed crushing chamber and form hammer powder, then they are directly discharged through the discharge port.
Third, the impact coal mining equipment adopts new type of gap-adjusting technology, that is, we do not need to change the hammer of coal crusher after which being worn; as long as to ensure the clearance between hammer and lining board, discharging granularity can be uniform and fine.
Fourth, the impact coal mining equipment adopts centralized lubrication system, we can also grease the machine without stopping it. Additionally, hydraulic starting unit can be easily repaired.
