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.

Grinding roller, grinding ring and spring of TGM trapezium mill

The innovative design of the grinding roller and grinding ring. Compared with Raymond mill, the grinding roller and grinding ring are designed in multi-stairs shape, which can reduce the speed of the material gliding between the trapezium mill roller and the grinding ring, increase the time of the material being grinded, and improve the fineness and output of the finished product.

Effective balanced and loaded spring. The trapezium grinding mill absorbs the merits of the Raymond mill and the suspension mill. The grinding roller assembly is connected with the horizontal spring through the pull-rod, producing the radial force which can avoid the wear and tear due to the large block of material entering into the grinding chamber, thus prolongs the service life of the equipment.
