Hammer crusher failure reasons and troubleshooting methods

In this era of rapid development, crushers began to fill the fields of industrial development. But when the machine breaks down, can you fix it quickly? Next, we will introduce the causes and troubleshooting methods of the hammer crusher.

Hammer crusher failure reasons and troubleshooting methods:

1. The machine vibrates.

Reason: When replacing the hammer head or due to the wear of the cone head, the static balance of the rotor does not meet the requirements; the hammer head is broken and the rotor is out of balance; the pin shaft is bent and broken; the triangular disk or the disk is cracked; the anchor bolts are loose.

Elimination method: remove the hammer head, select the hammer head according to the weight, make the total weight of the hammer on each hammer shaft equal to the total weight of the hammer on the opposite hammer shaft, that is, the static balance meets the requirements; replace the hammer head; replace the pin shaft; electric welding Repair or replace; tighten anchor bolts.

2. There is a percussion sound inside the machine.

Reasons: non-broken objects enter the inside of the machine; the lining plate fasteners are loose, the hammer hits the lining plate; the hammer or other parts break.

Remedy: stop and clean the crushing cavity; check the fastening of the lining plate and the gap between the hammer and the screen; replace the broken parts.

3. The bearing is overheated.

Reasons: Insufficient grease; Too much grease; Contamination and deterioration of grease; Bearing damage.

Remedy: add an appropriate amount of grease; the grease in the bearing should be 50% of its space volume; clean the bearing; replace the grease; replace the bearing.

4. The discharge particle size is too large.

Reason: The hammer head is worn too much; the screen bar is broken.

Remedy: replace the hammer; replace the screen.

5. Production is reduced.

Reason: The screen bar gap is blocked; the feeding is uneven.

Remedy: stop, clear the blockage in the screen gap; adjust the feeding mechanism.

6. The elastic coupling produces percussion sound.

Reason: loose pin; wear of elastic ring;

Remedy: stop and tighten the pin nut; replace the elastic ring.

Seeing this, I believe you have understood the causes and troubleshooting methods of the hammer crusher. In the event of a failure, it can respond calmly and calmly.
