① The vibration impact causes fasteners to loosen and fall, forming baffle plate or chute side plate fall.
(2) Materials mixed with foreign bodies, foreign bodies are hard, angular, falling coal tank plugging dead.
(3) Short roller, damaged or rolling failure.
④ The belt runs off seriously and scratches the frame.
2. Reasons for the cracking of the tape.
① Due to the constraint of space scale, the belt has many bending times.
② joints have been vulcanized for many times due to various reasons.
3. Reasons for tear of vulcanized joint
① The diameter of the reversing drum is small, and the belt bears large bending stress.
(2) The quality of vulcanized joints is poor, especially when the vulcanized joints have bubbles or cracks along the lap edges, the strength of the joints decreases significantly.
(3) Short operation cycle, frequent startup, instantaneous tension.
4. Cover up the damage cause of the rubber surface
(1) The open space between the guide groove liner and the belt is inappropriate, constituting abnormal wear, or the empty space is embedded with foreign matter, constituting abnormal wear or scratch.
② The flow rate of the material in the guide groove is inconsistent with the speed of the belt, and the drop is large, which accelerates the wear of the rubber surface.
(3) Rollers are damaged, constituting abnormal wear or scratches of the belt.
The cleaner is scratched.
(5) Belt slip, will also constitute belt abnormal wear.
