Open and closed circuit dry grinding of cement mill

2004-1-14 · Closed circuit grinding testsClosed circuit experiments were carried out at a constant mill stirring speed of 600 rpm. The product from the mill was conveyed to an air separator via a spiral conveyor. As an adjustable parameter the spiral's conveying capacity was used at three levels, namely 800, 1700 and 2800 g/min.

2011-2-1 · Tube mills having multi-chambers are traditionally used for cement grinding either in open or closed circuit operations. In the first chamber, larger balls (100–60 mm) are used for coarse grinding while the smaller balls (40–15 mm) are used for fine grinding. The chambers are separated by an intermediate diaphragm which allows the passage of the fine particles to the second chamber while
