Analysis of Grinding Roller Stress Distribution of

The quality of powder of non-metal materials directly relates to the force exerted on grinding roller, while the force on grinding roller relates to the thickness of the material layer. The uneven pressure distribution between the roller and material layer is caused by the drum-shaped characteristics of vertical mill grinding roller. This paper studies the pressure distribution of roller in

Comparison of grinding characteristics in high-pressure

Grinding is a process in which a coarser feed is ground to a specified fineness of x. However, an over-grinding fineness of y should be specified, and the size interval between x and y (-x+y) is a suitable size fraction for separation. Considering over-grinding in the grinding process, the grinding technical efficiency (E t) (Duan, 2012) is
