Friction plates for conveyor belts are manufactured from a metallic plate which is 2mm thick, covered by a layer of vulcanised rubber. Its surface is patterned with different shapes and the surface of the drive pulleys must be patterned.
Depending on the diameter of the drum, the metallic plate is curved, while the metallic surface is protected from the weather by a layer of paint.
Friction plates come in a choice of widths and two lengths: 180mm and 384mm – the rubber is 15mm thick. The client chooses the characteristics of the rubber mixture.
