BALL MILL Meaning and
Definition
-
A ball mill is a type of grinder that is used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel, stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber.
The ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed. For systems with multiple components, ball milling has been shown to be effective in increasing solid-state chemical reactivity. Additionally, ball milling has been shown effective for the production of amorphous materials. It is used for solid-state reactions between reactive components of mixtures containing solids, such as ceramics. It is also used for cold welding of metals, where the deformation leads to a change in the material's structure.

Etymology of BALL MILL
The word "ball mill" originates from the combination of two words, "ball" and "mill".
The term "ball" refers to a spherical or oblong object, often made of metal, that is used in various activities, such as sports or games.
The term "mill" is derived from the Latin word "molina", meaning "a mill, millstone". In its original sense, a mill is a machine that grinds or crushes materials into smaller pieces by the action of rotating hammers, wheels, or other mechanical devices.
When combined, the term "ball mill" describes a machine that uses rotating cylinders filled with balls of various materials to grind or mix substances. This machine is commonly used in industries like mining, ceramics, metallurgy, and construction to reduce the size of particles and homogenize materials.
