Crusher as the main equipment in the sand production process, its stable operation is the basis to ensure stable production. But after all, it is a machine, failure is inevitable. How to reduce the failure rate, reduce the failure generation, but we can control. So, what are the common failures of sand crusher? How to fix it? Here is a detailed introduction:

crusher
1, bearing frequent fever
Reasons: There are many factors that cause the bearing to heat, such as improper installation, frequent machine vibration, lubrication is not done, the working environment temperature is too high, the bearing itself quality and wear problems.
Solution: Install and reinforce the machine correctly according to the operation instructions, and add appropriate amount of grease; Clean the bearing; Replace bearings, etc.
2, equipment vibration is too large
Cause: The base is loose, the hammer head is replaced or the rotor static balance is not required due to cone head wear; The hammer head is broken, the rotor is unbalanced; Pin buckling and breaking; A triangular or disk crack; Anchor bolts are loose.
Solution: tighten the anchor bolt, remove the hammer head, select the hammer head according to weight, so that the total weight of the hammer on each hammer shaft is equal to the total weight of the hammer on the relative hammer shaft, that is, the static balance meets the requirements; Replace the hammer head; Replace the pin; Welding to repair or replace triangle or disc; Tighten the anchor bolts.
3, the discharge particle size is too large
Reason: hammer head wear is too large; The screen is broken.
Solution: Replace the hammer head; Replace the sieve strip.

• Production declines
  Reasons: uneven feeding, material viscosity humidity is too large, screen bar is blocked;
  Solution: Adjust the feeding speed, dry the material, stop the machine to check the screen, and clean up the gap blockage.

5, the machine produces foreign body sound
Reason: Foreign body into the machine; Liner fastener slack, resulting in plate hammer impact on the liner; Plate hammer or other parts are broken.
Solution: Stop the machine, clean the crushing chamber; Check the tightness of the liner; Replace broken parts.

6. The elastic coupling produces a tapping sound
   Cause: pin loose; Elastic ring wear.
   Solution: Stop the machine and tighten the pin nut; Replace the elastic ring.
   This article mainly introduces the common faults and solutions of sand crusher in the production process, mastering these can basically solve more than 80% of the problems in production, and doing these work is also a basis for ensuring sustainable and stable production.
