Abstract The results of a detailed study on material flow through a grate-discharge (open-end) ball mill versus an overflow-discharge (constricted-end) ball mill are presented to emphasize the effect of discharge-end design on mill transport characteristics. The effect of feed rate to the mill, mill rotational speed and ball load on the residence time distribution of the flow regime, the

The fluid flow or the transport problem in the ball mill is intimately related to the porous structure of the ball charge. It is clear that if the voids in the bell bed are filled by the material being ground then the slurry will add to the pool formed beneath the ball bed.

Abstract The rod mill product is characterized by its narrow size distribution if it is compared with that of a ball mill operating under the same conditions in open circuit. This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes (the grinding kinetics aspect), and partly due to the nature of material flow through the mill with its rod load (the

Material is fluidised through a porous media with low-pressure air, and flow is achieved by sloping the Airslide conveyor to match the fluidised angle of repose of the powdered material. These air-gravity systems provide high-capacity material handling while offering many economic and environmental advantages.

In general, ball mills can be operated either wet or dry and are capable of producing products in the order of 100 μm. This represents reduction ratios of as great as 100. Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity.
