In June 1998, the world's largest grinding mill, the 40 ft (12.2 m) diameter 20 MW Cadia gearless SAG mill, was commissioned. This was a leap of over 40% above the largest operating SAG mill. A significant saving in capital cost gave the incentive necessary for a single mill line at Cadia, resulting in the selection of the 40 ft (12.2 m ...

A SAG mill, or semi-autogenous grinding mill, operates on the principle of autogenous or self-grinding. It uses a combination of ore and grinding media to break down larger rocks into smaller pieces. Understanding the working principles of a SAG mill is crucial for anyone involved in the mining industry. In this section, we will delve deeper ...
