BALL MILL •Size reduction occurs by impact of balls in ball mill. •In a large mill the shell diameter is 3m length is The balls are of 25125mm in diameters. •During the time of rotation, the balls are picked up by the mill and carried nearly to the top, where they break contact with wall and fall to bottom and picked up again.

Size reduction is a process of reducing large unit masses into small unit masses like the coarse or fine particles. Size reduction is also known as comminution or diminution or pulverization. Generally this process is done by two methods: Precipitation method: In this method, the substance is firstly dissolved in an appropriate solvent and then after it is finely precipitated by the addition ...

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.

Impact, compression, shear, and attrition are the most common mechanisms associated with size reduction. One method of size reduction is the ball mill. The ball mill is a type of grinder that grinds materials into fine powder. When heavy balls of material fall on and crush the material being milled, grinding occurs.
