Reason：

  1. excessive wear of hammer head;

  2. fracture of sieve strip.

Exclusion methods:

  1. replacement of hammer head;

  2. replace sieve strip.

Fault 2: bearing overheating.

Reason：

  1. insufficient grease;

  2. excessive grease;

  3. grease pollution and deterioration;

  4. bearing damage.

Exclusion methods:

  1. add proper amount of grease;

  2. the bearing inner grease shall be 50% of its space volume.

  3. cleaning bearings and replacing grease.

  4. replacement of bearings.

Malfunction 3: elastic coupling produces knock sound.

Reason：

  1. the pin shaft is loose;

  2. wear of elastic ring;

Exclusion methods:

  1. stop and tighten the pin nut;

  2. replace the elastic ring.

Malfunction phenomenon 4: the machine produces a knock sound inside.

Reason：

  1. Non-broken matter enters the machine;

  2. the liner fastener is relaxed and the hammer hits the liner;

  3. broken hammer or other parts.

Failure phenomenon 5: reduced output.

Reasons: 1) the crevice of the sieve is blocked;

  1. uneven feeding. Elimination methods: 1) stop the car and clean up the clogging in the crevice of the sieve strip;

2)adjust the feeding mechanism.

Failure phenomenon 6: vibration sudden.

Reason:

  1. when replacing the hammer head or because of the wear of the cone head, the static balance of the rotor is not required.

  2. the hammer head is broken and the rotor is out of balance;

  3. bending and breaking of pin shaft;

  4. cracks in triangular or circular disks;

  5. loose anchor bolts.

The elimination methods are as follows:

  1. removing the hammer head and selecting the hammer head according to the weight so that the total weight of the hammer on each hammer shaft is equal to the total weight of the hammer relative to the hammer shaft, that is, the static balance meets the requirements;

  2. replacement of hammer head;

  3. replacing pin shaft;

  4. repair or replacement of electric welding;

5)fasten the anchor bolt.
