Conveyor belt in use and roller friction, generally the friction between the two kinds of equipment is inevitable. However, in actual use, the friction between the conveyor belt and the idler will become larger, so that the service life of both equipment will be reduced. Therefore, the friction between the conveyor belt and the idler should be minimized in the process of use. The following take you to understand the cause of abnormal wear between the conveyor belt and roller and preventive measures.

I. The causes of wear between roller and conveyor belt mainly include installation error, structural deformation of roller frame and roller corrosion. Sorted as follows:

1, roller frame installation is not correct; Under the support of the roller, the conveyor belt generates a certain friction force to ensure its normal operation. Due to improper installation, the shaft line of the roller is not vertical to the center line of the conveyor belt, and the conveyor belt slides relative to the roller, aggravating the wear of the conveyor belt.

2, aligning roller deviation correction wear; When the aligning roller is rectifying deviation, a certain tilt Angle will be generated. Due to the processing quality and rust, the rotary frame will not rotate flexibly, and the conveyor belt will be worn if it cannot rotate and reset in time.

3, roller rotation lag; Due to the quality problems of the idler itself (such as lax sealing, inflexible bearing rotation, etc.), the rotation of the idler lags behind the running speed of the conveyor belt, causing the relative sliding between the idler and the conveyor belt to wear the conveyor belt.

Two, belt machine roller and conveyor belt to prevent wear maintenance measures

1. First, ensure that the whole conveyor belt is on a Central Line; Secondly, both sides of the tilt roller and the middle horizontal roller have the same tilt Angle, all the middle roller in the same level, so that all rollers and conveying with good contact, to ensure that each roller uniform force.

2. Use aligning roller as little as possible.

3. Strengthen the daily maintenance of idlers, and replace the damaged idlers in time.

Conveyor belt wear is one of the more common faults, but if not paid attention to often cause more serious accidents, so take appropriate measures to reduce the wear of conveyor belt, prolong the service life, the normal operation of belt conveyor and reduce maintenance costs has a very practical significance.
