The SMW series of pin mills was designed for fine grinding as well as de-agglomeration of soft and medium hard minerals up to 3 Mohs. On these pin mills, both sets of pin discs are driven, either in the same or in opposite directions. With counter-rotating pin discs, the resulting tip speed is over 200 m/s which enables grinding to a high fineness. Airflow through the mill assists the grinding, enables the control of the product temperature and provides a method for pneumatic transfer of the product. The SMW can also be used as an efficient method of coating ultra-fine fillers.
