Other factors. (1) Height of retaining ring. The height of the retaining ring directly affects the stability of the material layer and the grinding efficiency of the vertical roller mill. If the height of the retaining ring is too high, this is not conducive to the overflow of the material, leading to the thickening of the material bed.
The model consists of grinding and separation sections. For the modelling of the grinding operation, breakage rates of the particles are correlated with design …
The rotary tillage knife roller, as one of the typical soil-touching parts of the tillage equipment cutting process, is in direct contact with the soil. During the cutting process, there are problems related to structural bending, deformation, and high power consumption, caused by impact and load, and it is difficult to observe the micro-change …
