Matters Needing Attention When the Jaw Crusher is Working

Apr.06, 2022
(1) The ore must be fed in the middle of the distribution plate, and it is not allowed to directly feed the ore into the crushing chamber. This is because it is easy to overload the jaw crusher and cause uneven wear of the lining.
The correct feeding conditions are:
A. The ore is evenly dispersed in the crushing cavity by the distribution plate.
B. The fed ore cannot be higher than the level of the rolling mortar wall
(2) The size of the jaw crusher should not be equal to the size of the feeding port, (the size of the feeding block ≤ 85% of the size of the feeding port), otherwise it will lead to:
A. The reduction of jaw crusher output.
B. Damage to some parts of the jaw crusher.
(3) The jaw crusher is not allowed to start under load, which will definitely cause an accident.
(4) When stopping, the jaw crusher must be stopped first, and the ore that has entered the crushing cavity is crushed and discharged, and then the jaw crusher is stopped.
(5) When the jaw crusher is working, the pressure of the locking system and the working conditions of the hydraulic station should be checked frequently, and problems should be dealt with in time.
 
output of jaw crusher
The output of the jaw crusher is related to the feeding method, the size of the feeding block, the size of the discharge block, the physical and mechanical properties of the ore, and the temperature. approximate throughput.
3. Replacement of rolling mortar wall
The rolling mortar wall has U-shaped screws on the adjustment ring, and zinc alloy is injected between the two to make it tightly combined. When the rolling mortar wall is newly installed or replaced, after working for 6-8 hours, the tightening condition should be checked. and tighten the U-shaped screw again.
4. Replacement of broken walls
The crushing wall is fixed on the cone body with a conical head, and zinc alloy is cast between the two. After the newly installed or newly replaced crushing wall works for 6-8 hours, its tightening condition should be checked, and it should be tightened immediately if it is found to be loose. .
5. Gear meshing
Due to the wear of the circular plate due to friction, the change of the gear gap is affected. In order to ensure the normal meshing of the gears, a gasket must be added on the bottom cover, and the thickness of the gasket should be equal to the wear amount of the circular plate.
