Size reduction by ankita yagnik
Working: The drug to be ground is put into the cylinder of the mill in such a quantity that it is filled to about 60% of the volume. A fixed number of balls are introduced and the cylinder is closed. The mill is allowed to rotate on its longitudinal axis. The speed of rotation is very important 26 27.

Working of Hammer mill
Working of Hammer mill: The hammers are allowed to be in continuous motion (8000 to 15000 revolutions per minute). The feed material is placed into the hopper, which flows vertically down and then horizontally, while hammers are in continuous motion. These rotating hammers beat the material to yield smaller particles.

How Does a Hammer Mill Work?
Hammer mills work in the principle that most materials will crush, shatter, or pulverize upon impact. 4. The Process: Material is fed into the mill grinding chamber through the feed chute, typically by gravity. It repeatedly is struck by ganged hammers which are attached to a shaft which rotates at high speed inside the mill chamber.
