The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs ... The product particle size distribution is narrow due to the vertical mill design coupled with the internal classification effect of the discs ...
The relative 'efficiency' of horizontal grinding mills compared to other comminution equipment is often debated, and efforts to improve the energy efficiency of these mills is an on-going area of attention for process engineers. The discharge arrangement design affects the material transport characteristics within a horizontal grinding mill.
separated and returned to the grinding zone, while acceptable material exits the mill to product collection in a cyclone or a baghouse. With the conventional roller mill design, when fine grinding, the classifier tails (rejected particles) are also quite fine and can be easily entrained into the airstream. However, the fine grinding roller mill is
