Grinding Ball Concentrate

Grinding the ore is ground into a fine powder by large rotating mills the two types used in the mission south mill are called sag semiautogenous grinding mills and ball mills sag mills use larger pieces of ore to break up the smaller pieces autogenous does it by itself the larger pieces break down as well

Grinding media such as steel balls ceramic pebbles or natural pebbles one inch in diameter or less are charged in the grinding chamber covering the screw flight agitator material to be ground is fed into the top center or bottom of the main body depending on the application and size of the feed
