How to eliminate jaw crusher problems during its operation

Jaw crusher is widely used in the concentration plant, it features strong inertial force, poor working conditions and heavy-duty work . In order to ensure continuous normal operation of the equipment , in addition to proper operation , regular and periodic maintenance , accurate and timely manner to determine and eliminate the possible failure is needed.

Major faults of jaw crusher during operation can be summarized as follows

1.When machine idling, the noise of metal crash

When jaw crusher no-load working , the lower metal crash occurs may be due to the following three reasons:

the crash of fixed jaw plate and movable jaw plate is due to the small port of discharge, it should be timely adjusted.

Elasticity of buffer spring disappeared or damaged

Bracket bearing badly worn or loose , it should be replaced immediately

2.when the machine working, there is metal crash and vibrating of lining board

This phenomenon is more due to the crushing chamber side liner and the tooth plate loose, fixed screws loosed or broken , they should be tightened or replaced promptly

3.Flywheel rotation , crusher does not work

Is due to the rod spring and rod damage , rod screw to release bearing slide bracket in from the prolapse , it may break off bracket should be installed to replace

4.Flywheel significant swing , slow eccentric shaft rotation

The fault belongs to the pulley and the flywheel key is loose or damaged , the wheel is not synchronized with the rotation axis

5. the granularity of final products is Very coarse

The lower part of lining board is seriously damaged. Teeth should be replaced and the port of discharge should be adjusted to meet the requirements
