1 INTRODUCTION IJSER

An attritor is a ball mill capable of generating higher energies and consists of a vertical drum with a series of impellers inside it. The impellers are set progressively at right angles to each other and have the func-tion of energize the ball charge, causing the powder size re- duction because the impact between balls, between balls and container wall, and between balls, agitator shaft, and ...
