However, because the grinding force (centrifugal force) of grinding roller was limited by grinding roller diameter and speed limits, the mill was applied to soft, low ash content and easy to wear materials. While the coal in Germany is much harder, and ash content is high, it needed higher grinding force.
Centrifugal roller mills use the centrifugal force of cylindrical grinding rolls to crush material into a uniform particle size and grind, turning materials into small granules or fine powder. Some of its typical applications include the particle size reduction of coal, glass, gypsum, limestone, and more.
