Structural Considerations Affecting Selection of Major Components in Grinding Mill Design

MINING has been practised by mankind for over sixty centuries (1). In 1876, the "ball mill" was patented, and during the century that followed rotary grinding developed to the state where individual machines are treating tens of thousands of tons of ore per day. This paper gives a brief description of design practices prior to the availability of advanced facilities, followed by modern analytical design development at Dominion over the past ten years.
