The Mine to Mill (M2M) strategy is a clear example of manipulating the relationship between plant throughput and feed particle size distribution (Kanchibotla, 2000;Morrell and Kojovic, 1999; Scott ...
· The feed to the mill is —4½" and the discharge is —20 mesh. To reduce iron contamination, no rods or balls or other grinding media are used in the mill. Disintegration of the material is aided by large lifter bars inside the mill. Feed is introduced to the mill by a large drum feeder designed specially to handle the large feed sizes without clogging. The feed – end trunnion liner is ...
