Abstract

In this article the new shape of lifters for Semi-Autogenous Grinding (SAG) and autogenous mills has been investigated. Lifters are designed for lifting, separating the grinding bodies (at SAG mill) and the grinding material to the required height of separation, crushing and grinding of the material in order to achieve the required output particle size. The main purpose of these mills is material grinding and crushing. Lifters are most used in the mining industry. Hence, attention is paid to analysis of different working regimes of mills with new lifter shape.
