Cause:
Improper transition between troughed belt and terminal pulleys
Solutions:
Adjust in accordance with our recommendations
Problem:
Excessive edge wear, broken edges
Cause:
Off-center loading or poor loading
Solutions:
Adjust chute to place the load on the center of the belt; discharge material in direction of belt travel at or near belt speed
Cause:
Material spillage and buildup
Solutions:
Improve loading and transfer conditions; install cleaning devices; improve maintenance
Cause:
Belt hitting structure
Solutions:
Install training idlers on carry and return run
Cause:
Bowed belt
Solutions:
For a newbelt, this condition should disappear during break-in; in rare instances, the belt must be straightened or replaced;
check storage and handling of belt rolls
Problem:
Transverse breaks at belt edge
Cause:
Belt edges folding up on structure
Solutions:
Install limit switches; provide more clearance
Cause:
Improper transition between troughed belt and terminal pulleys
Solutions:
Adjust transitions in accordance with Continental ContiTech Handbook of Conveyor and
Elevator Belting
Cause:
Severe convex (hump) vertical curve
Solutions:
Decrease idler spacing in vertical curve; increase curve radius; consult us for assistance
Problem:
Short breaks in carcass parallel to belt edge, star breaks in carcass
Cause:
Impact of material on the belt
Solutions:
Reduce impact by reducing the chute design; install impact idlers
Cause:
Material trapped between belt and pulley
Solutions:
Install plows or scrapers on return run ahead of tail pulley
Problem:
Ply separation
Cause:
Insufficient transverse stiffness
Solutions:
Replace with the proper belt
Cause:
Pulleys too small
Solutions:
Use larger-diameter pulleys
Cause:
Heat or chemical damage
Solutions:
Use the belt designed for specific condition
