Selection and justification of a technology for improving the wear resistance of ball mill liners

Abstract

Under conditions of intensive abrasive and impact wear, typical of ball mill operation, the use of conventional high-manganese steel 110G13L as a lining material proves to be insufficiently effective. This study substantiates the feasibility of using M1-grade chromium-molybdenum steel as an alternative material for mill drum lining. Laboratory investigations of the composition, microstructure, and properties of M1 steel were conducted, along with an analysis of the production technology and heat treatment. The results confirm the potential of the proposed alloy in enhancing wear resistance and operational reliability of the lining.
