The fineness of the processed material depends on the time the material stays in the grinding chamber ("dwell" time). Dwell time is controlled by the pumping rate. The slower the pumping rate, the longer the dwell time and the finer the grind. The grinding media used in continuous grinding mills range in size from 2mm to 10mm in diameter.Web
