Chapter 10 Selection of Fine Grinding Mills -
2007-1-1 As for the selection of fine grinding mills, each mill has its own advantageous particle size range for the individual feed materials. Impact milling has generally its own grinding limit size of around 10 μm with typical minerals at even higher tip speed of 100 m/s . Compression milling with roll mills is usually effective in the range of several tens of μm but high-compression milling is capable of efficient finer grinding combined with an impact mill
