Counterattack broken is mainly composed of fixed jaw and movable jaw plate, at the time of work mainly by the motor drive belt and pulley, through the eccentric shaft to move up and down movement of hubei, change size, Angle between bracket and hubei hubei near when the plate rack teeth, the crushed material, when tooth plate leave, crushing cavity has broken good automatically excluded by gravity, can continue to run production. Daily check the breaker frequently, found the problem in time. When there is uneven discharging granularity of crusher, carefully to find the cause of the failure occurs, the malfunction in time, avoid the trouble machine downtime. Here is to fight break out of the grain-size analysis of the causes of uneven:
1. The motor wiring location, host drive the car (dynamic jaw clockwise), or motor delta connection in y connection.
2. The shift of the jaw, addendum as opposed to a tip.
3. After the moving jaw and bearing wear clearance is too large, result in relative rotation of the bearing outer ring.
4. The discharge spout like in specified limits.
5. The broken material hardness or toughness than the prescribed scope of operation instruction.
6. Work the voltage is too low.
Counterattack is all sorts of production line, crushing work one of the important equipment in mining, the application scope of such a broad, it is determined by its own characteristics and performance of counterattack broken main characteristics are crushing strength is larger, construction is simple, convenient maintenance, uniform granularity, reliable work, etc. Widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry, and many other industries, is suitable for crushing various material compressive strength less than 320 million mpa.
