| 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. |

materials and the operating environment. This will help extending the service life of the conveyor
belt. |
