How the Circulation Process Works
The unique principle of the circulation mill is the high circulating (pumping) rate. The entire contents of the holding tank are passed through the mill at least once every 7-1/2 minutes, or about 8 times per hour. This high pumping rate results in a faster grind and a narrower particle size distribution. This phenomenon is explained by the ...
