TECHNICAL NOTE CASCADING MILL - A PHENOMENOLOGICAL DESIGN FOR IMPROVED GRINDING

The need to improve the technology associated with traditional methods of crushing and grinding has been an undisputed area of debate. Yet, there is very little structural and design improvement for increased c apacity and energy utilization of the mill. This paper discusses the r esults of some of the design and test work done on a cascading type mi ll that is a modification of a ball mill. Basically, the cascading mil l is designed to operate at super critical speeds but the charge is re stricted to move in a cascading manner. Thus the number and intensity of collisions per unit time is increased. Results of laboratory experi ments show that the cascading mill performs better than a ball mill.
