Made of high-grade abrasion proof alloy steel through carburizing thermal treatment, roller shell feathures
Uniform hardness and long service life. There are various roller surface patterns such as open-end corrugation type, closed-end corrugation type and dimple surface type. The dimension of eccentric shaft and other parts in the roller assembly are precise, which facilitates gap adjustent according to user's requirement, and maks assembly and disassembly as wellas roller shell replacement much easier
