Two of the three data sets were used to calibrate the ball mill and hydrocyclone models. At first step, measured data were adjusted using NOR-BAL 3 mass balancing and data reconciliation software (Spring, 1992). Then, using adjusted data the selection function of tube ball mills was estimated by NGOTC software (Farzanegan, 1998).

Fine granulation and greater efficiency

2011-3-8  Compared with a fluidised bed jet mill, the high density bed jet mill offers more efficient processing of low density materials, as well as less risk of contamination from residual materials. The ultimate result of all of these factors is that manufacturers are able to achieve both a fine particle size and high throughput grinding.
