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.
