Wear-resistant ceramic roller is a new kind of ceramic roller, it is the perfect substitute of normal ceramic roller, metal roller, plastic roller and rubber roller.

1, High strength and good wear-resistance.

2, Long working life, and can reduce abrasion of straps.

3, High-temperature resistant, antioxidation and good corrosion resistance, can be used in all kinds of bad environment.

4, There is no static electricities on it, so it won’t bring sparks when be impacted or rubbed, so it is applicable to explosive environments such as coal wells.

5, Stable capacity, so it can well stop belt conveyer from running deflection, heating firing and slipping.
