Hammer Mill.
Construction: The mill consists of a metallic case, rotor, a central shaft with hammers, screen, feed and outlet. The metallic case contains a rotor at the middle which has attached four to seven swinging hammers. The motor is moved with the help of electricity and speed of which can be controlled with the help of panels.

CLASSIFICATION OF MILLS USED IN PHARMA INDUSTRY
Hammer Mill:-The hammer mill is one of the most versatile and widely used mills in the pharmaceutical industry. The principle of size reduction in the hammer mill is one of high-velocity impact between the rapidly moving hammers mounted on a rotor and the powder particles. These mills can produce a wide range of particle sizes, even down …

Ball Mill
A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.

SIZE REDUCTION
Working: At low speeds, the ball roll over each other and attrition (rubbing action) will be the predominate mode of action. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Advantages: It can produce very fine powder. Ball mill is used for both wet and dry grinding processes.
