Conveyor Belt Problems & Solutions Continues...
Hello, Good Evening Everyone....!!!
Today we are continuing our earlier blog '' Conveyor Belt Common Problems & Solutions". We covered three points yesterday now let us move on to next.
4. Belt runs off at the head pulley:-
A. Material build- up on the pulley face or conveyor structure. Clean system, improve material containment, install cleaners, check skirting, install belt scrappers at head pulley.
B. The pulley and or the idlers are out of square with the belt centreline. Readjust pulleys and or idlers.
C. Pulley lagging is worn or not adequate to produce sufficient traction. Replace with new or correct pulley lagging.
D. Idler stands are not centred to the belt. Readjust the stands for proper alignment.
5. Belt runs off at tail pulley:-
A. The belt is running off centre as it comes around the tail pulley and/or through the load point. Re-track belt, install traning idlers on the return prior to the tail pulley.
B. Material build-up on the pulley face or conveyor structure. Clean system, improve material containment, install cleaners, check skirting, install belt scrapers in front of pulley.
C. The pulley and or the idlers are out of square with the belt centreline. Readjust the pulleys and or idlers.
D. Frozen, dirty or misaligned return idlers. Clean rollers, properly align rollers, install cleaning devices at head pulley, use self cleaning rollers, improve maintenance.
E. Inadequate belt tension is possible, recalculate tension requirements. If necessary increase weight on gravity take up or increase tension at screw take-up.
6. Belt runs to one side for a considerable distance, or the entire conveyor:-
A. The belt is running off centre as it comes around the tail pulley and/or through the load point. Re track belt, install training idlers on the return prior to the tail pulley.
B. Build up of material on idler rollers. Clean and maintain. Install scrappers, brushes and other cleaning devices.
C. The pulleys and or the idlers ar out of square with the belt centreline. Readjust pulleys and or idlers.
D. Idler stands are not centred to the belt. Readjust the stands for proper alignment.
7. Belt slip when conveyor starts:-
A. Insufficient traction between belt and driven pulley. Make sure drive pulley is free of build up. Lag drive pulley. Increase belt wrap on drive pulley. Increase belt tension.
B. Counter weight hitting bottom , not enough belt tension. Shorten belt and re-splice.
C. Pulley lagging is worn or not adequate to generate suffficient traction. Replace with new or correct pulley lagging.
D. One or more of the system pulleys are below the acceptable diameter. Replace pulleys with diameters. acceptable to belt requirement.
E. Conveyor is overpowered. Reduce HP or consider a soft start if applicable.
