- Reduced processing capacity and reduced output:
Reason analysis: the gap of the sieve bar is blocked by the material; the feeding is uneven.
Solution: Suspend the operation of the equipment to clean up the material blockages in the gap of the screen; adjust the feeding mechanism. - There is a knocking sound inside the machine:
Cause analysis: non-broken objects enter the inside of the machine; the fasteners of the lining board are loose, and the hammer hits the lining board; the hammer or other parts are broken
Solution: (1) Suspend the operation of the equipment and clean the crushing cavity; (2) Check the tightness of the liner and the space between the hammer and the screen, and adjust the spring to ensure that the gap between the two ends of the grinding roller is consistent. The tooth needs to be repaired. (3) Replace broken parts. - The bearing is overheated:
Cause analysis: shortcomings of lubricating grease; excessive lubricating grease; dirty and deteriorated lubricating grease; bearing damage.
Solution: add appropriate amount of lubricating grease; grease in the bearing should be 50% of its space storage; clean the bearing; replace the lubricating grease; replace the bearing.
- The discharge granularity is too large:
Cause analysis: the hammer is worn too much; the screen bar is broken.
Solution: Replace the hammer head; replace the sieve bar. - There is an impact sound on the elastic coupling:
Cause analysis: loose pin shaft; wear of elastic ring;
Solution: Stop and tighten the pin nut; replace the elastic ring. - Large amount of vibration:
Reason analysis: 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 or broken; the triangle disc or the disc is cracked; the anchor screw is loose;
Solution: Remove the hammer head and select 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 on the hammer shaft, that is, the static balance meets the requirements; replace the hammer head; replace the pin shaft; electric welding repair Or replace; tighten the anchor screws.
