reasons belt breakage and repair

A conveyor belt longitudinal tear reasons:
(A), shock and vibration caused by fasteners loose and fell off, causing the coal chute liners, steel cement silo, etc. fall.
(Two), the material inside the inclusion of foreign, foreign body rigid, angular, coal chute blockage Jisi.
(Three), roller defect, roller frame cause scratches.
(Four), a serious deviation after rack conveyor caught.
(Five), Sweepers winding roll (return sweeper), loose bolts, there are a harbinger of spring.
Second, the belt cracking reasons:
(A), due to the limited spatial dimensions, concrete block machine belt more times.
(Two), the joint vulcanization due to various reasons more than twice sulfide.
Third, the conveyor belt vulcanized joints torn reasons:
(A) small diameter idler pulley, belt withstand large bending stress.
(Two), conveyor belt vulcanizing joint quality is poor, especially in curing more than twice, the joint strength decreased, or in the bonding layer when the canvas is cut or polished drain, where strength decreases.
(C), the reversing conveyor, lap top and bottom can only in one direction, it is easy on the belt cleaning device, and other equipment angular portion unloading scratches.
(Four), conveyor duty cycle is short, frequent starting, the instantaneous tension force.
