The effect of processing parameters on energy
· Ball mills are vertical or horizontal cylinders (statio-nary tank) equipped with a rotating shaft with arms filled to as much as 70 of the available volume with grinding media (usually steel balls). The mass and the balls are agitated by a shaft with arms rotating at a variable speed. Generally size reduction in any practical machine is achieved by mechanical forces (compression impact or shear) that cause rupture while one of the forces is usually predominant. In the ball mill
