ensp0183enspthe mill. Maintain an adequate ball charge too low a ball charge is one of the leading causes of locked charge starts, especially in ball mills. Power draw should be maintained over 75 of mill rated power. A locked charge mitigating start procedure must be utilized if the mill is shut down for 15 minutes or longer.
Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and The center of gravity first starts to shift to the left as the speed of rotation increases but autogenous mill or a mixture in a semiautogenous mill, as well as the slurry that makes up the operating charge.
