To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.
The concentrator is divided into a central transmission concentrator, a peripheral transmission concentrator, a high efficiency concentrator, a sludge concentrator, a batch concentrator, a vertical flow and a radial flow continuous concentrator.
8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill.
According to this definition, given that the energy utilization in a ball mill is between 1×10 −3 and 4×10 −3 m 2 /J, and that the crack resistance value is between 30 and 60 J/m 2, the theoretical efficiency of the ball mill should be in the range of 1.5–12%.
