| Problem | Cause |
|---|---|
| Belt will not track Edge wear |
– Mechanical problem – Pulleys out of alignment/Bad Bearing – Crooked splice, belt out of square – Material build up on pulley – Off-center loading – Improper crown or pulley – Damaged belt – Uneven moisture absorption in belt from storage – Cambered belt |
| Lace or vulcanized splice failure |
– Wrong size fastener – Fasteners not properly – Belt too tight – Under belted – Belt speed too high – Poor tracking (see above) – Pulley too small for belt – Poor Splice |
| Cleat Failure | – Pulleys too small – Belt hitting return idlers – Poor tracking of belt – Product overload – Product or environment attacking belt – Pulleys too small |
| V-guide delamination/cracking |
– Pulleys too small – Belt/conveyor misaligned – V-guide and pulley grooves do not match – Temperature too high or too low – Chemical attack – Improper slack side tension or overall tension |
| Slipping or stalling | – Poor pulley lagging or not enough pulley wrap – Suction of belt or slider bed – Too low of drive horsepower – Too high of coefficient of belt to conveyor – Material jammed in chute |
| Top cover wear | – Improperly installed chute lining – Exposure to heat or oil – Belt slipping on drive |
| Bottom cover wear | – Frozen idlers – Rough or worn slider bed or pulleys – Material build up on pulleys |
