Analysis of failure causes, prevention, and troubleshooting methods 1. Tape slipping. 1. The friction coefficient between the drive drum and the belt is low, or the wrap angle is too small ； 2. The tension of the tightening device is too low ； 3. The load capacity is greater than the design capacity. 1. Increase the friction coefficient and the wrap angle ； 2. Proofread and adjust the tensioning force ； 3. Reduce the load capacity to ensure it does not exceed the designed value. 2. A part of the tape suddenly deviates from its path. 1. The tape is partially bent ； 2. The centers of the joints are not aligned. 1. In severe cases, replace the bent section ； 2. Reconnect the joint. 3. Deviation when running without load. The tape has poor grooving capability. Replace it with tape that has good tracking properties or use self-adjusting idlers. 4. Excessive wear on the edges of the tape. 1. Excessive deposits on idler rollers and drums ； 2. The idler rollers or guide rollers are not properly adjusted ； 3. The bracket is not level ； 4. Automatic adjustment of idler rollers and guide rollers is faulty ； 5. The bulk material enters between the belt and the bracket ； 6. The unloader is not properly aligned. 1. Install a valid cleaner ； 2. Re-adjust ； 3. Re-adjust ； 4. Adjust or replace ； 5. Clean thoroughly ； 6. Inspect and adjust the unloader. 5. Abnormal wear of the upper adhesive. 1. When discharging material from chutes, materials such as limestone that have sharp edges move at a speed different from that of the conveyor belt ； 2. The return idler does not rotate ； 3. Chute blockage. 1. Adjust the chutes to change the speed at which the material slides down ； 2. Clean and replace the idler rollers ； 3. Improve the chutes. 6. The upper adhesive layer has long longitudinal splits. The chute isn’t installed properly. Readjust the assembly. 7. The edge wears down into strip-like shapes. The baffle is not aligned properly. Adjust the baffle. 8. Abnormal wear of the lower layer adhesive. 1. Tape slipping ； 2. Debris entering the return section ； 3. High moisture content in the material leads to a decrease in the friction coefficient ； 4. The idler rollers do not rotate. 1. Check the tensioning device ； 2. Clean and inspect the load-bearing section ； 3. Reduce material moisture ； 4. Clean and adjust the idler rollers. 9. Tape pleated skirt. The drum is slipping. Improve the grooving on the tape or increase the coefficient of friction. 10. Abnormal noise from the idler bearing. 1. The bearing has been in use for too long ； 2. Poor lubrication. 1. Replace and inspect the bearing ； 2. Apply lubricant after cleaning.
