Roller adjustment：

Check the rotation of the roller regularly to ensure that there is no jamming or abnormal noise. For rollers that do not rotate, replace or repair them in time. At the same time, adjust the position of the roller to keep it in proper contact with the conveyor belt to reduce wear.

Fastener inspection：

Loosening of fasteners is one of the common causes of fireproof conveyor belt failure. Check whether fasteners such as bolts and nuts are loose regularly, and tighten them in time to prevent vibration and noise caused by looseness.

Transmission inspection：

Check the operation of the transmission (such as motors, reducers, couplings, etc.) to ensure smooth transmission and no abnormal vibration and noise. For aging transmission parts, replace them in time.
