Vertimill® - Metso Outotec

Vertimill® is typically arranged in closed circuit and fed by the cyclone underflow. The motor power turns the Vertimill® screw at constant speed to stir the grinding balls and slurry. As the particles are ground, they rise to the top of the mill and overflow into the separating tank.

Jan 14, 2004  Closed 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.

Cement mill - Wikipedia

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill
