Common faults and solutions of gravel crusher

Sand and gravel crusher is a common production equipment in the field of mining, construction site and other fields, and its function is to crush the stone materials coarsely or finely to meet different production requirements. However, as the operation time of the gravel crusher grows, some failures or problems often occur, affecting the normal operation of the equipment. The following will introduce the common faults and solutions of gravel crusher.

First, the common faults and causes of gravel crusher

1. Failure 1: excessive vibration of the crusher

Reason: loose ground bolt, loose hammer head, broken liner plate, insufficient lubricant, etc.

2. Failure two: crusher noise is too large

Reason: bearing damage, gear wear, coupling clearance is too large.

3.Failure three: low crushing efficiency

Reason: material is too big, wear and tear of wearing parts, feeding speed is too fast, etc.

 Second, gravel crusher failure solutions

1. Solve the fault of excessive vibration: check whether the ground bolts are fastened, and tighten

 them in time if they are loose; check whether the hammer head, liner plate and other parts are loose, 

and repair or replace them in time; add lubricating oil regularly to keep the equipment lubricated.

2. Solve the fault of excessive noise: check whether there is wear and tear of bearings, gears, couplings and other parts, and repair or replace them in time; adjust the coupling gap so that it reaches the specified value; add lubricant regularly to keep the equipment lubricated.

3. Solve the faults of low crushing efficiency: check the material size, adjust the feed size in time; check the wear and tear of wearing parts, repair or replace them in time; adjust the feed speed to avoid overloading the equipment too fast.
