Description

Technical field

[0001] The invention relates to a vertical mill, in particular to a vertical mill used for grinding various materials in industries such as metal mines, non-metal mines, energy sources, and new materials. Background technique

[0002] The vertical mill commonly used in industry is a kind of roller mill. Its basic principle is to place the material to be ground between the grinding roller and the grinding disc, and use mechanical force such as spring force and hydraulic pressure or centrifugal force generated by rotation. It is crushed and crushed. This kind of grinding equipment using the principle of material bed extrusion and crushing has the characteristics of higher grinding efficiency, lower power consumption and less wear than the grinding equipment using shear and impact force. There are many types of vertical mills. Here, a widely used MPS vertical mill with a rotating disc and a relatively stationary roller (not revolving around...
