Crusher operation and maintenance and common troubleshooting

Even the best equipment, after a long time, there will be some minor problems, the crusher is the same. Therefore, after using the machine for a period of time, it must be regularly repaired and inspected to ensure the normal operation of the crusher.

First, check if the shaft of the flywheel is swinging left and right. If so, re-tighten the tightening sleeve.

Secondly, check the rack for cracks, crack, repair or replace the new frame, and fix the fixed bolt bolts.

Then, a knocking sound is generated at the rear of the frame, the spring seat is installed in place, and the tie rod nut is tightened to the proper position.

Finally, the rack jumps heavily, the foundation is reinforced, padded sleepers or rubber, etc.

Common troubleshooting of crushers:

1, the bearing is overheated

Cause: Insufficient grease; excessive grease; deterioration of grease contamination; bearing damage.

Remedy: Add a proper amount of grease; the grease in the bearing should be 50% of its space volume; clean the bearing; replace the grease; replace the bearing.

2, the discharge granularity is too large

Cause: The hammer is too worn; the screen is broken.

Plastic crusher troubleshooting method: replace the hammer head; replace the screen.

3. Reduced output

Cause: The gap of the sieve is blocked; the feeding is uneven.

Remedy: Stop, clean the blockage in the gap of the screen; adjust the feeding mechanism.

4, the elastic coupling produces a knocking sound

Cause: the pin is loose; the elastic ring is worn;

Troubleshooting: Stop and tighten the pin nut; replace the elastic ring.

5, the inside of the machine produces a knocking sound

Cause: Non-crushed material enters the inside of the machine; the lining fasteners are loose, the hammer hits the lining; the hammer or other parts break.

Remedy: Stop, clean the crushing chamber; check the fastening of the lining and the gap between the hammer and the screen; replace the broken parts.

6, machine vibration

Reason: When the hammer is replaced or the cone is worn, the static balance of the rotor is not satisfactory; the hammer is broken, the rotor is out of balance; the pin shaft is bent and broken; the triangular disk or the disc is cracked; the anchor bolt is loose.
