Our Conveyor Belt
Rubber Grade: Wear Resistance
There are several wear resistance grades for conveyor belt ranging from the general purpose grade to the highly wear resistance grade. Which one to use is depending on the type of conveying materials and the operating environment.
  Grade: P
 
General Purpose
Widely use. Suitable for use in normal temperature environment. Not suitable for conveying oily materials, high temperature surface, sharp surface, or acid-alkaline materials.

   
  Grade: N
 
Normal Wear Resistance
Suitable for abrasive or heavy load materials like Asbestos, Ash, Bauxite, Cement, lime etc.

   
  Grade: M
 
Maximum Wear Resistance
Excellent abrasion and high impact resistance. Suitable for conveying bulk, heavy, sharp edged, high abrasive materials.
