Failure and elimination of hammer crusher:
1、Bearing overheat: grease; excessive grease; grease contamination deterioration; bearing damage.
Removal method: the filling amount of grease; bearing grease should be the space volume of 50%; bearing cleaning; replacement of grease; replacement of bearings.
2, the delivery of large particles: hammer wear is too large; screen strip fracture.
Removal methods: change the hammer; change the screen bar
3, yield reduction reasons: screen strip gap is blocked, uneven feeding.
Removal methods: stop, clean the gap in the screen bar, adjust the feeding mechanism
4, the elastic coupling cause knock reason: pin loose; elastic ring wear;
Removal method: stop and tighten the pin nut; change the elastic ring
5, Cause knocking within the machine: the non broken material enters the machine; the lining fastener is loose; the hammer strikes on the lining; the hammer or other part breaks
Removal method: stop and clean the crushing chamber, check the fastening of the lining plate and the gap between the hammer and the screen bar, and replace the broken parts.
6, a sudden increase in vibration reason: replace the hammer head or because of cone wear, make the rotor static balance not meet the requirements; hammer head broken, rotor imbalance; pin axis bend, break; triangle or disk cracks; anchor bolt loose
Removal method: remove the hammer, hammer made by weight selection, a total weight of hammer shaft hammer and hammer shaft relative to the total weight of the hammer is equal to the static balance to achieve the requirements; replacing hammer; replacement pin; welding repair or replacement; tighten the anchor bolts.
