Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and ...

Introduction. The ball mill abrasion test (BMAT) is an industriallyrelevant multipurpose wear test method that enables tribologists and abrasion scientists to study the abrasive wear behaviour of materials for various service applications, particularly for grinding balls and mill liners, under conditions and contact mechanics very similar to the industrial ball mills.

The optimum ball mill parameters to achieve a small particle size of µm include a ball mill speed of 500 rpm, a milling time of 10 h, and a balltopowder ratio (BPR) of 10:1. These settings are sufficient for obtaining better results. However, the study does have certain limitations that could be addressed in future research.
