The working of a ball mill is based on impact and attrition: the impact, caused by the balls dropping from top of the shell, breaks down the particles, thereby resulting in reduction in size. Ball mill includes a hollow cylindrical shell which is rotated about its own axis.

: 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 ...

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.

BALL MILL/TUMBLING MILL • Principle: impact b/w rapidly moving balls and powder material. At low speed balls roll over each other attrition takes place. • Construction : • 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.

6. The ball mill can be divided into wet ball mill and dry ball mill according to the use environment. The difference is that the structure of the dry ball mill is more complicated than that of the wet ball mill. The discharge port of the dry ball mill is straight and equipped with an air induction device, a dust exhaust pipe and a dust collector.
