loose, causing the rack bearing no gaps in both sides, so that the eccentric shaft stuck, unable to turn; 4)workplace voltage is too low, which causes the host
encounter aniseed,and the inability broken; 5) bearing damage.
Remedy:1)removing obstruction of the discharge opening to ensure the smooth flow of materials; 2)tighten or replace belt; 3)to re-install or replace the bush sleeve;
4)align the workplace voltage to conform to the requirements of the host operating voltage; 5)replacement bearing.

Reasons:1)tension spring break; 2)rod fracture; 3)off or broken of the bracket
Remedy:1)replace tension spring; 2)replace the rod; 3)to re-install or replace the bracket
Symptom 3:stunned Crusher spring break.
Reason: emphasis on small Jaw Crusher discharge opening with the spring tention.
Remedy: Replace the spring.
Symptom 4:flying sheave shaft swing.
Reasons:1) flying sheave shaft hole slot, flat key or shaft wear and loose in coordinating; 2)stone rolling into the inside of the wheel result in cracking of the flying
sheave wheel shell; 3)casting defects; 4)flying sheave expansion sleeve looses.
Remedy:1)flat key wear, replace the flat key, or replace the eccentric shaft or fly wheel slot; 2)by doing flying tank round shield and replace the eccentric shaft or fly
wheel slot; 3)replace the eccentric shaft or tank round. 4)Re-tight set up sleeve
