Double roll crusher (also called twin roll crusher) is composed of two cylindrical rollers as the main working mechanism (Figure 1). When working, the two round rollers rotate in opposite directions, and the material (ore) is crushed by the friction between the rollers, which rolls the material into the crushing cavity formed by the two rollers.

Nip behavior depends substantially on kinetic friction factor. Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the
