The ball mills are rotary equipment used in mining plants in grinding, which uses steel balls to reduce the particle size of the ore as shown in Fig. 1. The rotating assembly of the mill is supported by two bearings, called trunnion bearings indicated in Fig. 2. The bearings are static components having bushings, on which the mill rotates.
