2.1. Crushing mechanism and model The main working part of the double toothed roller crusher is two parallel installed crushing rollers, through which the material is broken by the compaction of the two broken rollers. The double toothed roller crusher is mainly divided into three stages to crush the material, as shown in figure 1-2:
Double roll crushing is a comminution principle that has already been deployed for more than 100 years. It is known for high throughputs of sometimes sticky materials such as overburden. However, its applicability for ore and hard rock processing has been underestimated in recent decades. The presented research results are suitable for drawing ...
