High quality conveyor belt requires the following:
1) Selection of most suitable rubber cover compound, appropriate type of belt construction (i.e., cover thickness, number of plies and interplay rubber thickness), and material reinforcing type and weave to suit the customer’s application.
2) Stringent adhesion to procedures to ensure the quality of the compounds mixed, and the fabrics supplied are of high integrity.
3) Care in the Calendaring and build up process to ensure that there is no air entrapment, and consequently minimal need for post-cure repairs.
4) Proper curing and pressing of the belt, with precure and post cure stretching. This ensures the belt is produced to a consistent thickness and does not bow or warp or will not over stretch on the system. These properties ensure the belt will track and perform properly on the system once installed.
5) Post cure testing of total belt strength, fabric to rubber adhesion, and checking the physical properties of the rubber covers to verify that the belt meets the specifications as quoted to the customer.
