Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

operation The ball mill consists of a hollow cylinder mounted in such a way that it can be rotated on its horizontal axis with a rotational frequency depend upon the diameter of the mill ≈ The cylinder may be of metal, porcelain or of rubber, to reduce abrasion. The balls may be of metal, porcelain or stones (pebble mill).

IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of :1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge. Frictional wear or rubbing forces act on the particles, as well as collision energy.

An attritor mill, also known as a stirred ball mill, is a type of milling equipment used for grinding materials into fine particles. It is characterized by its unique working principle, which involves a highspeed rotating shaft with agitator elements. The agitator elements consist of impellers or discs that are mounted on the shaft and rotate ...

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.

Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]]. To produce the qualified size and high liberation of granule for the subsequent separation is the primary objective of the grinding operation [4,5].
