Study the effect of number of balls and speed of ball mill on the particle size reduction using ball mill. 4.
Attrition: Attrition occurs when particles are rubbed or sheared against each other, resulting in size mills, ball mills, and fluid energy mills mainly use this mechanism. Cutting: Cutting mechanisms involve using sharp blades or knives to slice or shear the mills and knife cutters are commonly used in this type of size reduction.
A pharmaceutical ball mill is a specialized machine used in the pharmaceutical industry to reduce the size of pharmaceutical materials.....
A hammer mill is essentially a steel drum containing a vertical or horizontal rotating shaft or drum on which hammers are mounted. 15. † The hammer mill operates on the principle of impact between rapidly moving hammers mounted on a rotor and the powder material. 19. † The hammer mill can be either the horizontal or vertical shaft type.
A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

Fundamentally, a ball mill comprises a vessel or vial filled with balls, or rods, constructed from a variety of materials such as ceramic, agate ...
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.
