Ball mill Wikipedia. Ball mill Wikipedia: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 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 It is partially filled with balls
Hammermills operate with close clearances between the hammers and the screen bars and they reduce by attrition combined with shear and impact reduction. Though attrition crushing consumes more power and exacts heavier wear on hammers and screen bars, it is practical for crushing the less abrasive materials such as low silica limestone or coal.
Mar 25, 2016 · 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. Fig: Ball mill .
The main mechanism of action in attrition mills is shear, due to friction between the particle and the pair of grinding surfaces. Unless the mill is cooled, the temperature rise may be considerable, particularly in the case of dry milling. A different kind of attrition mill .
Combined impact and attrition methods • Fluid energy mill * Jet energy mill: Air is injected as a high pressure jet through nozzles at the bottom of the loop. The high velocity of the air gives rise to zones of turbulence into which solid particles are feed. The high kinetic energy of the air causes the particles to impact .
