How to Deal with Damaged Rollers and Idlers

Rollers and idlers are also crucial components of a belt conveyor. The normal operation of the belt mainly relies on the drive of the rollers and the support of the idlers. Whether the rollers and idlers can rotate normally and flexibly plays an essential role in the normal operation of the conveyor.

The main issues with rollers during the use of the belt conveyor are:

1. Wear of the roller surface rubber or detachment of the surface rubber;
2. Cracking of the roller surface;
3. Increase in temperature of the roller bearing housing or damage to the bearings;
4. Breakage of the roller main shaft. Once a roller encounters a problem, the belt conveyor will be unable to operate normally.

The main issue with idlers is that inflexible rotation increases the resistance of the belt operation, and when the idler surface is worn, it may also cause longitudinal tearing of the belt and other accidents.

Handling methods:

1. Inspect the condition of the rubber surface on the rollers at least once a day. If the rubber wear exceeds the standard or is abnormal, the operation should be stopped in a timely manner and personnel should be organized to re-rub the rollers.
2. Regularly organize maintenance to add lubricating oil to the roller bearing housing and measure the wear of the bearings. Before the bearing wear reaches the limit value, organize personnel to replace the roller bearings.
3. Organize maintenance workers to patrol the tunnels. If a damaged idler is found in the tunnel, replace it on the spot.
