The problems and solutions in belt conveyor use
(1)Belt slips when conveyor is started.
1. Insufficient traction between belt and drive pulley. Make sure drive pulley is free of build up.
Lag Drive pulley. Increase belt wrap on drive pulley. Increase belt tension.
2. Inadequate belt tension is possible, recalculate tension requirements. If necessary increase
weight on gravity take up or increase tension at screw take-up.
3. Pulley lagging is worn or not adequate to produce sufficient traction. Replace with new or
correct pulley lagging.
4. Counter weight hitting bottom, not enough belt tension. Shorten belt and re-splice
5. One or more of the system pulleys are below the acceptable diameter. Replace pulleys with
(2)Belt runs off at the head pulley.
1. Material build-up on the pulley face or conveyor structure. Clean system, improve material
containment, install cleaners, check skirting, install belt scrapers at head pulley.
2. The pulleys and or the idlers are out of square with the belt centreline. Readjust pulleys and
or idlers.
3. Pulley lagging is worn or not adequate to produce sufficient traction. Replace with new or
correct pulley lagging.
4. Idler stands are not centred to the belt. Readjust the stands for proper alignment
