### A study of comminution in a vertical stirred ball

The median size of the products from the batch stirred ball mill experiments closely matched those of the continuous grinding experiments under similar grinding conditions. Using a salt solution as a tracer material, an attempt was made to estimate the residence time distribution based on a simplified analysis of the motion of the water in tile mill.

Get Price### Predicting the product particle size distribution

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

This accurate scale up is different than scale up for ball mills or other stirred milling technologies. In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill. Additionally while techniques like the Bond Work Index and "scale up factors" are

Fig. 2 shows the average particle size distribution of products obtained for grinding additives dosage. The average particle size of ground products was decreased with the increase of additives dosage from 0.05 to 2.4% by weight of the solids. Beyond this dosage for two chemical additives an increasing trend of fineness was observed. Hence 2.4% of additive concentration can be chosen as the
