### Flow of materials in rod mills as compared to ball mills

25-01-2012· 1. Introduction. Comminution kinetics in tumbling mills involves two main sub-processes, namely, transport and breakage. Transport and breakage of materials in ball mills have been frequently reported (Abouzeid, 1989a, Abouzeid et al., 1974, Abouzeid and Fuerstenau, 1972, Abouzeid, 1973).The breakage kinetics in rod mills has been illustrated by several investigators (Abouzeid,

### Axial transport in dry ball mills - ScienceDirect

01-11-2006· Ball mills are used for grinding of rocks, cement clinker and limestone from 10 to 100 mm feed sizes down to sub-millimetre product. They are typically rotating cylinders with diameters from 3 to 6 m and lengths from 6 to 12 m. The flow of particulate solids within these mills can be modelled using the discrete element method (DEM).

### Flow of materials in rod mills as compared to ball mills

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

### Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

### Optimizing your SAG mill operation - International Mining

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal. In addition, operating mills at
