A ball mill typically consists of a cylindrical drum partially filled with balls, typically made of steel or ceramic. The drum is mounted on a horizontal axis and is rotated by a motor. The mill also includes a feed hopper, which is used to introduce the material to be ground, and a discharge chute, which is used to remove the ground material.
Ball mill is used in the pharmaceutical industry to produce the fine particles of the drugs. It consists of a metal cylinder that can rotate on a horizontal axis and grinding medium (i.e. stainless steel or porcelain balls). Grinding of particles is accomplished by the impact and attrition of the balls in the rotating ball mill.

Ball mills are among the most variable and effective tools when it comes to size reduction of hard, brittle or fibrous materials. The variety of grinding modes, usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications. Cooling, heating & cryogenic grinding.
The cylinder contains balls occupying 30–50 % of mill volume. The weight of ball is constant; Size depends on the feed quantity and diameter of mill. Determination of particle size and Shape . Size of ball. Feed rate. Speed of rotation of cylinder. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding ...
A ball mill consists of various components that work together to facilitate grinding operations. The key parts include the following: Mill Shell: The cylindrical shell provides a protective and structural enclosure for the mill. It is often made of steel and lined with wear-resistant materials to prolong its lifespan.

Considerable and selective formation of degradants occurs already after very short reaction times of less than 15 minutes and the nature of ... Ball milling – a new concept ...
In the ball mill the particles receive impacts from balls or stones and are subjected to attrition as the balls slide over each other. Principle of 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 ≈ 0.5 r.p.s
1. It produces very fine powder (particle size less than or equal to 10 microns). 2. It is suitable for milling toxic materials since it can be used in a completely enclosed form. 3. Has a wide application. 4. It can be used for continuous operation. 5. It is used in milling highly abrasive materials. See more
