With the single-roller mills, brittle, soft to medium-hard materials can be reduced in size with a reduction ratio of approx. 1:5 to 1:5. The stepped arrangement of the crushing jaws on the crushing wall enables any material rolling off being minimised, so that, compared to the double-roller mill, coarser material can be drawn in. Double-roller ...

They are widely used after crushers for further size reduction or before the fine milling and pulverization. As a rough indication, the lowest size usually achievable by impact mills is around 0.1 mm. They traditionally have dealt with relatively soft materials such as limestone, phosphate, gypsum, shales, coals, etc.

It was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 µm to P 80 product size of 275.4 µm while stirred mill consumed 32.45 kWh/t of energy to produce the product size of 235.6 µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.
