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.

To evaluate the effect of a stud diameter, which is placed on a roll surface, simulations were performed for three types of HPGR having 13-, 6-, and 3.75-mm studs. Simulation results show that the working roll gap increased when a smaller stud was used. This suggests that a roll surface with a smaller stud was likely to provide a stronger force.
