A ball mill is a type of grinder 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. E.

A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. 15. † The hammer mill operates on the principle of impact between rapidly moving hammers mounted on a rotor and the powder material. 19. † The hammer mill can be either the horizontal or vertical shaft type.

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.

The high energy ball milling devices are of three types namely: shaker mills, attrition mills, and planetary ball mills (Suryanarayana 2001). Shaker mills have a vial where grinding media,, milling balls and sample are swung vigorously toandfro for several times causing an impact of milling ball against each other, with the sample and ...

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 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.

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. 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).
