The truth about population balance modeling

This wet ball mill model, comprising the assumed breakage function, solids residence time assumed to be that of liquid, and back-calculated breakage rates, works quite well in circuit simulations. All three individual elements, however, are false. The model cannot be used to assess changes to the mill itself. While shrouded from proper vetting ...

Ball Mills

To facilitate this process, Retsch displays the strength and efficiency of each ball mill model in a spider-net diagram, see Figure 3. A planetary ball mill, for example, offers a big jar volume compared to a mixer mill and shows a high value on this diagonal. A mixer mill in contrast offers various possibilities for temperature control and has ...
