1.Applicable to grind and mill raw material. The roller body material adopts wear resistance iron and alloy steel, and rollers also are treated by quenching process.
2. Hardness value may reach HRC60°~62°, On the roller body is equipped with material distribution device.
3. Not only the entire roller body width may play the grinding role to enhance the grinding fineness and the output, also may cause the roller body uniform wear, effectively solved the middle wear phenomenon.
