Common Faults In Parts Of Screening Machine For Coal Mining

Some parts of the Screening Machine For Coal Mining will wear out or damage even after a long time. Common faults include tube beam fracture, beam fracture, and screen frame fracture.

Tube Beam Fracture

Beam Break

The beam breakage is mostly due to the working time at the critical frequency is too long, the high-strength bolts of a large number of fastening side plates are slack, and the springs are severely deformed, so that the difference between the left and right heights is extremely large, and the weight error of the eccentric mass may be too large, causing damage to the structural parts. The beam is broken. At this time, the damaged structural parts and beams should be replaced, and the bolts should be tightened to adjust the quality of the eccentric block.

Screen Frame Break

The screen frame is prone to breakage due to tremor. The best way to solve this problem is to thicken the side panels or add attachment to the local area of ​​the side panels near the exciter to enhance the rigidity of the entire screen frame.
