The article analyzes virtual experiments of the lining of a ball-type drum mill depending on a number of factors: the diameter of a mill, the diameter of grinding bodies, the number and height of liner lifters. The numerical experiment was performed using the EDEM software; a parametric model of the mill housing with variable liner lifters was created and imported, studies were performed using the virtual simulation method. A virtual experiment made it possible to study the grinding process without interacting the equipment which eliminates the risk of injury during and allows for more accurate research data. As a result of simulation of virtual experiments, values of the average kinetic energy of grinding bodies and the number of their collisions were determined.
