Raymond mill parts: grinding roller, grinding ring

Raymond mill parts includes grinding roller and grinding ring. And grinding roller and grinding ring are mainly made of the following two kinds of materials:

a) 65Mn

The durability of grinding roller and grinding ring made of 65Mn can be improved remarkably. 65Mn is characterized by high hardness, high wear resistance, and being magnetic. It’s mainly used in deironing-required powder processing industry. In addition to the major needs for iron. And its mechanical properties can be greatly improved after heat treatment, which makes it have high wear resistance and greatly improved toughness.

b) Mn13G2
Compared with 65Mn, the durability of grinding roller and grinding ring made of Mn13G2 is also improved. The water toughening treatment is conducted after casting pouring. Then, the casting becomes non-magnetic and has high tensile strength, toughness, plasticity, which makes the toothed plate more durable. When it is deformed due to severe impact and strong pressure during use, the surface hardening and the martensite takes shape to form a high wear-resistant surface layer. While with good inner toughness, even if worn to very thin, it can also withstand greater impact loads.
