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 ...

3. The ball mill is very noisy machine, particularly if the casing is of metal, but much less so if rubber is used. 4. Relatively long time of operation. Critical speed of ball mill: The faster the mills are rotated the further the balls are carried up inside the mill and the greater the power consumption and capacity of the mill.

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
