Lm Description: 1. Groove roller with anti-corrosion characteristics: its acid salts are not corrode. 2. Groove roller hardness: wear resistance. 3. Groove roller ceramic surface: forming an oxide film on the surface is smooth, non-stick material, in contact with the belt friction coefficient is small, reducing the winch driving force. 4. Low operating costs: groove roller conveyor belt can reduce the overall cost, reduce maintenance man hours. 5. Sealing: groove roller sealed at both ends with plastic labyrinth seals, slick oil will not leak, can scroll long axis; groove roller running in sealed condition. 6. Groove roller Long life: groove roller than steel rollers 2-5 times using a long time, and can reduce belt wear, belt does not run side to extend belt life. Groove roller is widely used in large open-air dust, high corrosion environments such as mines, power plants, steel mills, stones factory, cement, coal washing, salt factories, soda, fertilizer plants, docks and other places all shipping frequent use of groove roller
