Milling is a widely used industrial operation common for cases where size reduction of particles is required. It involves the size reduction of particles smaller than 10 mm. There is a vast range of mill types available, such as ball mills, vibratory mills, rod, jet, and cage mills. For a larger diameter, planetary ball mills can be used.

ball to powder ratio in ball mill
The ball milling of metallic powders using a high planetary mill in inert atmosphere leads to many modifications of particle microstructure. Indeed, during the ball milling which can be performed in various types of high energy mills, powders are trapped between colliding balls and/or balls and vials are subjected to high stresses.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%

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.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
