In the entire beneficiation process of a concentrator, grinding operation cost accounts for a considerable proportion. The grinding fitness is one of the main factors affecting the mineral processing index,which will directly affect both the grade of concentrate and the recovery rate of product. Therefore, how to improve grinding fineness of the ball mill becomes an important part of ...

The grind index is calculated performing a mass balance around the ball mill circuit to estimate the cyclone overflow density (viscosity effect) and a correction factor due to specific power consumption (size effect). The grind cut index is maintained by controlling the addition of water to the cyclone feed. This water control method sets the ...

The efficiency of fine grinding in the second compartment is largely controlled by the size of grinding balls. Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range ...
