## The effect of processing parameters on energy

2015-2-10 · 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 refiner the feed material is comminuted between the grinding media, the stirrer and the cylin-der wall by compression and shear [7,8]. The factors affecting the grinding action of the ball mill are the mill speed and quantity, type and size of grinding media. The aim of this study was to examine the effect of agitator shaft speed and amount of grinding media (steel balls) on energy consumption of a laboratory ball mill.
