Abstract

Today, in most of the mining projects, especially with high operating capacity, using of AG and SAG MILLs become more common, due to their special features, comparing with other conventional GRINDING mills. Usually in comminution process a small percentage of energy is merely consumed by GRINDING and crushing processes. Also, the comminution process is dependent on many parameters such as: ore hardness, charge volume, size and geometry of ore, charge and size of balls, percentage of critical velocity of mill and LINER PROFILE. Therefore, achieving the optimum mentioned factors and consumed energy is of particular importance. Since, it is impossible to consider interaction of all effective parameters simultaneously, by employing experimental methods because of their high expenses and being time consuming, so in this research the effect of LINER PROFILE on comminution process was investigated by changing the height and angle of liners using numerical method (finite element methods, FEM). In this approach the height and angle of liners were determined by estimating the stress of the particles impacts with liners. The results showed that a liner with a height of 140 mm and an angle of 15 degrees has the maximum impact and breakage of particles. The results achieved from FEM model for the Sarcheshmeh Copper Complex SAG MILL were in good agreement with the measured data from experimental SAG MILL.
