Conveyor Belt Common Problems & Solutions
Hello, Good Evening Everyone....!!!
Today we are back with a most general topic'' Common Problems of Conveyor Belts & Solutions''.
1. Excessive top cover wear over entire top surface or in load carrying area:-
A. The top cover quality is not adequate for the system/material being conveyed. Upgrade to a heavier top cover. Upgrade to a better cover compound.
B. Off centre loading or improper loading of the belt. Make sure loading chute places the load in the centre of the belt. Make sure the direction of the material down the chute is in the direction of the belt travel.
C. Material build up on the pulley faces of the return idlers,or on the conveyor structure itself. Clean system, improve material containment, install cleaners, check skirting, install belt scrappers after the head pulley.
D. Frozen, dirty or misaligned return idlers. Clean rollers, properly align rollers, install cleaning devices at head pulley, use self cleaning rollers, improve maintenance(alignment, lubrication and cleaning.)
E.Too much distance in between the idlers causing excessive material movement as the load travels up and over the idlers. Decreases the distace between idlers, increase tension in the belt is under tensioned.
2. Excessive pulley cover wear:-
A. Frozen Idlers. Replace or repair frozen idlers. Replace or repair frozen idlers. Improve maintenance of idlers (Lubrication, cleaning, alignment).
B. 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 if the belt is under tensioned.
C. Material build up on the pulley face or conveyor structure. Clean system, improve material containment, install cleaners, check skirting, install belt scrappers in front of pulleys.
D. Material is getting trapped between belt and pulleys. Improve containment at load point. Improve containment along the conveyor. Install ploughs or scrappers in front of tail pulley. Practice good house keeping.
E. Bolt heads from pulley lagging or from slider bed material hold down on the bare backs, are sticking up and catching the belt. Inspect and replace or tighten as required.
F. A condition of tilted or over tilted troughing idlers exists. Idler frames should be located per manufacturer recommendations, usually at 90 degrees to the belt and conveyor frame. Align idlers per manufacturers recommendations.
3. Excessive edge wear:-
A. The belt is misaligned. Track and train belt.
B. Belt is coming in contact with the conveyor frame and or hardware. Make sure belt is tracking properly. Make sure there is proper clearance between belt and any hardware. Make sure load is centred of the belt. Clear any jamed material. Install training idlers on carry and return side of belt.
C. Off centre loading or improper loading of the belt. Make sure the load chute places the load in the centre of the belt. Make sure the direction of the material down the chute is in the direction of the belt drive.
D. If the edge wear occurs in the splice area, the splice may have been installed crooked. Resplice belt.
