One way of fully utilizing a ball mill is to convert it from an overflow to a grate discharge. Consider mill power draw, product, throughput and conversion costs.
As can be seen from Fig. 7, the contents inside the pulp lifter are always in contact with the grate till they get discharged into the trunnion, and hence flow-back becomes inevitable. As the mill speed increases, the greeter influence of centrifugal force causes discharge to occur later leading to carry-over of a fraction of the fluid (Fig. 8 ...

Peripheral Discharge Ball Mills. The several layers of balls lying on top of those next to the shell follow a similar cycle except that, due to relative difference in the two forces, their paths become more nearly vertical. The outer layers, spreading more than the inner layers, increase the area in the zone of the falling balls.

The overflow ball mill is mainly used for the wet grinding various ores. In the grinding process, while continuously feeding materials to the mill, a certain amount of water is also continuously fed, so that the finely ground materials and water form a mixed fluid. The ore pulp is discharged from the mill in a self-flowing manner to complete ...
Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 25-75 microns. Both continuous and batch style ball mills use centrifugal force, gravity and hard media to break up industrial materials into fine pieces or powder. Ball milling systems grind dry material and wet slurry alike.
A ball mill is a type of grinder used to grind materials into extremely fine powder. It consists of a cylindrical container with grinding media, typically steel balls. The ball mill rotates around a horizontal axis, partially filled with the material to be ground plus the grinding medium. The centrifugal forces created by the rotating motion cause the media to grind …

How a Grate Discharge Ball Mill Works. Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is "pumped" out and discharged.
