As the jig tailings are sent directly to the flotation machine, a slightly finer mesh screen is required on the ball mill than when a closed grinding circuit is used. Even with this fine screen, a much coarser feed goes to flotation than when only classifier overflow is being treated. The gravity flow principle of the "Sub-A" Flotation ...

The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
