The rate of ore addition was dictated by the need to maintain the mill at a constant total weight, which was measured by the loadcell mountings and shown on a large display in the pilot plant area. In order to shorten the period required to stabilise the mill, the desired weight of ore was loaded into the mill prior to each test.
