Equipment failure rate is minimal and the maintenance of the equipment in later period is extremely important. Mine must be allocated to the plate in the middle , forbidding the mine goes into the crushing cavity directly. Because it is easy to make crusher overload and the liner wear unevenly .
The condition of giving mine:
a. Mine evenly was distributed in the crushing cavity through the distribution plate.
b. Feeding ore can't higher than the level of rolling acetabular wall.
The crusher to the maximum size of giving mine couldn't be allowed equal to the mine mouth size ( the maximum size of giving mine = 85% to the mine mouth size) ,or they will lead to :
a. Crushers yield reduced.
b. Damage to certain parts of the crusher.
2. Crushers are not allowed to start overloading , because the overload will start the accident.
When the crusher will finish the work,at first we must stop to the mining machine . When crushing the mine goes into the crushing cavity after discharge ,it can make crusher stop.Crusher should be always checking the pressure and hydraulic locking system work station , once we identify problems and handling in time .
3. Crushers' output
Crushers' output, and feeding methods , feeding degradation, platoon ore blocks degrees size,mechanical properties, temperature and so on . Varies greatly,the manufacturer of a given output is sketchy the quantity in the specified conditions.
4. The replacement of rolling acetabular wall
Rolling acetabular wall with U shape screws embedded in the adjustment of the ring, both between infusing zinc alloy and making closely. New installation or the replacement of rolling acetabular wall, in the work six to eight hours we should check for tightening situation ,and once again tighten the u-shaped screw.
5. Gear mesh
The circular plate is worn by friction , affecting variations in the clearance of the gear . In order to ensure the proper meshing gears must be supplemented...
