A side by side study: RoM ball and AG mill with F80 around 50 mm and a mill product P80 of around 250um, indicated the OWI is also considerably higher, and although it is known to be biased against finer products, the difference is sufficiently large to indicate that the RoM ball mill is less efficient than AG milling.

The ball mill-hydrocyclone circuit and the ball mill-screen circuit were sampled in order to measure and compare the performance of the circuits. The ball mills are different in design. Therefore, simulation studies were carried out to eliminate the differences in factors affecting the performance of the circuits such as milling conditions.

The ball to charge ratio may be 5:1, 10:1, 15:1. This method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 40-10 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
