The GS high-speed fine crushing roller machine is made of high chromium alloy and high manganese steel materials, with a hardness of up to HRC50-60. The hardness reaches the surface hardness of the gear after heat treatment, and the shear pin has an overload safety effect. The roller end face is sealed and specially processed with a convex shape, which effectively improves the service life and makes the entire roller width play a crushing role. The high manganese steel roller machine has a normal working life 3-5 times that of ordinary cast steel roller machines. Due to its exceptional wear resistance, it is one of our company's key recommended products.
