Prediction of product size distributions for a stirred ...

In this paper, the difference between ball mill grinding and stirred ball milling is discussed. A size-energy model is proposed for simulation of stirred ball milling. The product size distributions below 10 μm from a stirred ball mill were simulated by the model satisfactorily. The model is

1999-11-1  The mill used for this study is a DYNO-Mill KDL laboratory-scale stirred bead mill as shown in Fig. 4.This comprises a 600-ml cylindrical grinding chamber filled to 80% with ZrO 2 beads (diameter=0.4–0.6 or 1.25–1.6 mm) stirred by four disk-shaped slotted blades. A pulley drive system allows four different speeds of rotation to be used (2125, 3675, 3385 and 4435 rpm).

A study of comminution in a vertical stirred ball mill.

The energy input per ton of grinding media in the stirred ball mill could be 10 times higher than for the tumbling ball mill. Although during coarse grinds the media wear was higher in the stirred ball mill than in the tumbling mill, it became less so as grinding proceeded and for a product median size of 4.8 microns it

The main objective of batch grinding modeling is the estimation of the product particle size distribution over time or specific energy input to the mill. So far, the developed analytical methods require often complicated calculations which are time-consuming. Thus, more simple approaches that allow the reliable prediction of the complete product size distribution need to be developed.
