Predicting the product particle size distribution from a vertical stirred mill
The mineral processing industry has seen an increased use of vertical stirred mills, owing to the inefficiency of ball mills for fine grind applications. The difficulty encountered in fine grinding is the increased resistance to comminute small particles compared to coarse particles. As a result, increased energy inputs are necessary to raise the number of collisional events in a mill contributing to the comminution of fine particles. In this study, a research program was designed and implemented to predict the performance of a laboratory scale vertical stirred mill using a Bond ball mill. An ...
