Material of vertical roller mill grinding ring

When the vertical roller mill works, the rolling distance between the skin mill and the center mill is very different, and the radial run out has little effect on the uniformity of the skin mill. According to the specific situation of our country, we can consider the mill for skin grinding and core grinding, and stipulate different radial runout. Due to the fluctuation of raw material composition and the shortage of testing instruments, the stability of quality needs to be improved. If we can strictly select the quality and then assemble vertical roller mill, the advanced grinding of the equipment will not be affected.

 

In addition, there are many problems to be solved, such as crown and roughening treatment. Due to the limitation of machine tools, taper is usually used instead of convexity to compensate for the effect of uneven grinding in the lengthening direction due to the bending deformation of the grinding roller. How to ensure the radial runout of the grinding roller needs to be studied and solved.

 

The material of the grinding ring of vertical roller mill is generally made of high manganese steel and other wear-resistant materials. Once the vertical roller mill is put into production, it will continue to work for a long time. Under the influence of the operation of vertical roller mill itself, when choosing the vertical grinding ring, we must choose the good material. Next, we will introduce the relevant knowledge about vertical grinding ring. For example, the manufacturing process of the grinding ring of v mill, higertical roller mill manganese steel is a kind of wear-resistant steel, which can obtain high plasticity and impact toughness after water toughening treatment.

 

High manganese steel has high wear resistance, high plasticity and toughness. When the high manganese steel of vertical grinding ring is subjected to external pressure and impact load, it will produce large plastic deformation or serious work hardening phenomenon. The hardness is significantly improved, so it has high wear resistance. In vertical roller mill, the products needed can be produced only by the mutual extrusion of grinding roller and grinding ring, so the materials of grinding roller and grinding ring are generally made of high manganese steel and other wear-resistant materials

 

Although it can't guarantee that vertical roller mill won't be damaged, we can take some measures to effectively extend its service life. The above is the explanation of the reason why the grinding ring is easy to be damaged in the vertical mill. During the working process of vertical roller mill, the grinding ring is seriously worn, and there will be huge friction between the two, because the squeezing and friction of the two are more serious As a result, a lot of vertical roller mill machine parts are seriously damaged.
