Rubber conveyor belt failure analysis and solutions

1 , belt tear :

Rubber conveyor belt selection using steel cord conveyor belt , the intention is to enhance the strength of the belt. But at the wire toward the south along the longitudinal rubber sheet , practice confirmed rope conveyor inadequate transverse strength , once damaged ( such as pallets, scrap hoisting ) it is easy to be torn open in the lateral , causing the belt elongation , fracture. Coupled with high temperature waste , accelerated aging rubber surface cracks appear , a significant decline in tensile strength , easily pulled off . Another reason is that the claw hooks quantity, density, big belt injury also improves the chances of the rubber sheet is torn .


2 , the solution:

Find the cause of the failure of rubber conveyor belts , respectively, connections and belt material improvement.

( 1 ) for connection to improve, making the hinge plate connection buckle. Advantages Improved : Install more stable and convenient ; joints to increase the contact area with the belt , small damage, a protective effect.

( 2 ) the belt replaced by a multi-layer rubber material cotton canvas ( cotton cloth ) from top to bottom is covered with high-temperature or heat-resistant rubber , high temperature resistant vulcanized rubber sheet bonded together to eliminate the plastic cracking phenomenon , increasing the cross longitudinal tensile strength .
