Hammer Crusher Breakdown And Exclusion

Origin:未知    Date:2017-03-02    Size:Small Medium Big
1. Bearing Overheating
Cause: Grease is low; grease is too much; grease is fouling; bearing is damaged.
Elimination method: filling the appropriate amount of grease; bearing grease should be 50% of its space volume;
cleaning bearings; replacement of grease; replacement of bearing.
2. The material size is too large
Reason: Hammer wear too large; sieve bar is broken.
Remedy: Replace the hammer; replace the sieve bar.
3. Production decreased
Reason: the screen gap is blocked; feeding uneven.
Exclusion method: stop working, clean up the cracks in the screen; adjust the feeding mechanism.
4. Elastic coupling produce percussion
Reason: pin loose; elastic ring wear;
Remedy: Stop and tighten the pin nuts; replace the elastic ring.
5. The machine produces a percussion sound
Reason: non-broken material into the machine; liner fasteners loose, hammer impact on the liner; hammer or other
parts broken.
Remove the method: stop, clean up the crushing chamber; check the tightening of the liner and the gap between the
hammer and the screen; replace the broken parts.
6. Machine vibration
Reason: Replace the hammer or due to the cone wear to make the rotor static balance does not meet the requirements;
hammer broken, rotor imbalance; pin bending, broken; triangular disc or disk cracks; anchor bolts loose.
Exclusion method: remove the hammer, according to the weight of the choice of hammer, so that the weight of each
hammer shaft on the weight of the hammer relative to the total weight of the hammer shaft equal, that is, static
balance to meet the requirements; replacement hammer; replacement pin; Repair or replace; fasten the anchor bolts.
