The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment). This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.

Comminution Wikipedia
Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
