The daily faults and solutions of sand and gravel crushers mainly focus on the following aspects:

​

1. The bearings often heat up

Reason: There are many factors that affect the heating of bearings, such as improper installation, frequent machine vibration, inadequate lubrication, high working environment temperature, and the quality and wear of the bearings themselves.

Solution: Install and reinforce the machine correctly according to the operating instructions, and add an appropriate amount of lubricating grease; Clean the bearings; Replace bearings, etc.

2. Excessive equipment vibration

Reason: When the base is loose or the hammer head is replaced, or due to wear on the cone head, the static balance of the rotor does not meet the requirements; Hammer head fracture, rotor imbalance; Bending and fracture of the sales shaft; Triangle or disc cracks; The anchor bolts are loose.

Solution: Tighten the anchor screw, remove the hammer head, select the hammer head according to the weight, so that the total weight of the hammer head on each hammer shaft is equal to its relative total weight on the hammer shaft, that is, the static balance meets the requirements; Replace the hammer head; Replace the pin shaft; Welding repair or replacement of triangles or discs; Tighten the anchor bolts.

3. Excessive discharge particles

Reason: Excessive wear on the hammer head; The sieve bar is broken.

Solution: Replace the hammer head; Replace the sieve bar.

4. Production decline

Reason: Uneven feeding, high viscosity and humidity of the material, and clogging of the sieve bar;

Solution: Adjust the feeding speed, dry the material, stop the machine to check the sieve bar, and clean any gaps or blockages.

5. Foreign object sound generated inside the machine

Reason: Foreign objects entering the interior of the machine; Loose fasteners on the lining plate caused the plate hammer to hit the lining plate; The hammer or other components are broken.

Solution: Stop the machine and clean the crushing chamber; Check the tightness of the lining plate; Replace broken parts.

6. Elastic coupling produces knocking sound

Reason: Loose pin shaft; Wear of elastic ring.

Solution: Stop and tighten the pin shaft nut; Replace the elastic ring.
