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.
