The function of vertical coal mill liner
The vertical coal mill liner is used to protect the coal mill cylinder and casing from the direct impact and friction of the grinding body and the material. At the same time, different forms of liner can be used to adjust the movement state of the grinding body. To enhance the crushing effect of the grinding body on the material, it is helpful to improve the grinding efficiency of the vertical mill, increase the output, and reduce the metal consumption. Conventional vertical mill wear-resistant liner types are corrugated, trapezoidal, T-shaped, etc.
Especially in the area of the inner mill barrel 2 meters above the grinding table, not only is the erosion serious, but also there are large particles of material impacted, and the traditional anti-wear treatment cannot achieve good results.
The sticky wear-resistant ceramic lining board can be installed within 2 meters above the grinding disc. This product is made of unique technology and has the characteristics of high hardness and high toughness. The screw is double fixed, especially suitable for use in places with high temperature and certain impact.
