The principle of the High Energy Mill (Simoloyer) is based on a horizontally borne rotor which allows an energy transfer in a homogeneous and high efficient way from supplied power to kinetic energy of balls (grinding media). The milling balls are accelerated by the rotating rotor and collide with each other at a relative velocity up to 14 m/s.

The Briggsian decay constant, here denoted as the attritional crushing strength, shows correlation with the Harwood–Pilpel crushing strength. Both crushing strengths show a correlation with the amount of granulating agent (povidone) added to the granulation, i.e., the more povidone added, the harder the granule.
A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.
In the mining industry, ball mill are used as grinding equipment at the comminution stage to liberate minerals from barren ores by reducing the feed material size. The most common types of grinding equipment are ball mills. A ball mill grinds material by rotating a cylinder with steel grinding balls, causing the ball to fall back into the cylinder and onto the …
