12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.

Principle: Works on the principle of Impact and Attrition. Construction: The mill consist of a hollow cylinder fixed on metallic frame in such a way that it can rotate around its horizontal axis. The cylinder contains metallic balls occupying around 30 to 50% of total capacity. The balls are usually made up of rubber, porcelain or metal.

BALL MILL Principle: • The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. • Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Working: • The drug is filled into cylinder 60% of the volume. A fixed number of ball introduced ...

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.

A section cutthrough of ball mills. A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser 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.

: 60% cylinder filled with material. Remaining balls are introduced to cylinder. And closed it with lid. Mills are allowed to rotate on axis. Speed of rotation play important role. At low speed, balls roll over each other and size reduction not occur at optimum level. At high speed, ball will stick to the wall of cylinder and no size reduction occur. At correct speed (optimum speed ...

BALL MILL Principle Th ball mill work on the principle of impact between the rapidly moving ball the powder materiel, both enclose in a hollow cylinder. At low speed the ball role over each other attrition will be predominant mode of action. Thus, in boll mill impact or attrition or both are responsible for size reduction.

Principle. Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

Principle of Fluid Energy Mill: It operates on the principle of impact and attrition. The inlet and outlets are attached with the classifier which prevents the particles to pass until they become sufficiently fine, (a). It helps in the determination of particle size and shape. The speed of air/inert gas is directly related to efficiency.
