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 single-stage fine grinding, regrinding, and as the second stage in two-stage grinding circuits.

Thus, the motion of a simple pendulum is a simple harmonic motion with an angular frequency, ω = √ g L ω = g L, and linear frequency, f = 1 2π√ g L f = 1 2 π g L. The time period is given by, T = 1 f = 2π√L g T = 1 f = 2 π L g. Performing dimension analysis on the right side of the above equation gives the unit of time.

What is a Ball Mill? A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
