motion of chargein aball mill
It is also similar to a ball mill because it uses balls usually ceramic ones having 515 mm in diameter Because the motion of the balls is independent of gravity an attritor can handle thixotropic materials and slightly higher viscosity of millbases but the principle of action and type of forces operating are similar to those of the ball mill
