A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.

Typical examples are the various ores, minerals, limestone, etc. The applications of ball mills are ubiquitous in mineral

Apr 01, 2012· In the current study, size reduction of the polymeric pellets was studied using a high and low energy mill. Since a majority of polymer pellets have a relatively large size (i.e., approximately 8.28 mm x 4.60 mm), high energy mills are logical choices for the milling process.

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.
