Crushing Principle and Theory Large Capacity double

2021-1-1  Crushing Principle and Theory. Material crushing is a long-standing topic. Crushing is quite complicated. It is not only related to the nature of the material being crushed (homogeneity, hardness, density, viscosity, block shape and moisture content), but also to the selected mechanical equipment.

Gyratory Crusher an overview ScienceDirect Topics

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the
