  How to deal with the abnormal noise of the crusher?

  Before the failure of cone crusher, the crusher often has some abnormal noise, which reminds us that some failures are about to occur, so how can we judge the abnormal noise of the crusher? How to deal with these abnormal noises when the crusher appears? The copper casting manufacturer will introduce you one by one:

  1) incorrect backlash causes abnormal sound. Adjust the backlash to the correct value;

  2) gear teeth are broken. Replace the gear;

  3) the transmission bearing is damaged. Replace the bearing;

  4) excessive load causes grinding noise near the bottom of crusher or the thrust bearing is broken. Excessive load may cause an increase in pressure between the thrust bearing faces. Check the return screen for excessive copper or lead debris. Copper and lead scraps need to be disassembled, inspected and replaced;

  5) the cone skin is loose and seriously worn. Shut down for maintenance;

  6) eccentric bushing is worn. Check the return screen for excessive copper or lead debris. Excessive copper and lead scraps need to be disassembled, inspected and replaced with eccentric bushing;

  7) the movement between the upper frame and the lower frame (bolt fracture). Replace and tighten the loose bolts. If the conical joint surface is worn, rusted or damaged, it shall be repaired by stacking or machining to reconstruct the conical surface. Note: the crusher can be operated temporarily by adding pad in the cone;

  8) the crushing cavity is blocked and the ore is hoarded. By lowering the moving cone, clear the crushing chamber or clean the ore manually
