Grinding Mills and Their Types – IspatGuru
In a well designed fluid energy mill, there is usually almost no contact between the charge and the mill lining. These mills are suitable for hard or soft materials to be reduced to 0.02 mm or less. This method of milling tends to be energy intensive and slow but is suitable where the product is highly sensitive to heat or contamination from grinding media.
