May 25, 2017 The “air-swept” method of operation of a mill eliminates the conveyor system which was often used in earlier types of plant to transport the product to the classifier and the oversize material from the classifier back to the mill. It is clear, however, that such a system can only be used successfully when the material undergoing treatment.
The above described mill construction affords a great advantage over prior constructions in that all ground product is cascaded through and contacted by the fluid stream at substantially its maximum velocity and good product removal is obtained with a minimum of power consumed in fluid blowing as compared with fluid swept mills in which the air.

In this respect, grinding performance of the air-swept ball mill was evaluated and modelled as a perfectly mixed single tank using the perfect mixing ball mill modelling approach (Whiten, 1974).
Oct 01, 1994 The grinding mechanism of a vibrating ball mill was examined by simulating the movement of the balls in a two-dimensional pot with circular vibration using a numerical calculation technique known as the discrete block method. The motion of the balls was also analyzed with the aid of video pictures.
