This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions. Mathematical descriptions of the method to estimate the volume-based residence time of slurry are presented. A database consisting of 121 sets of ...

Undercharging your mill in this manner will increase the milling times Figure 4: Undercharged media with overcharged load. relative to a properly charged mill. One key to efficient milling is a properly charged milling jar. "Charge" refers to

If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.

Open Circuit Grinding. The object of this test was to determine the crushing efficiency of the ball-mill when operating in open circuit. The conditions were as follows: Feed rate, variable from 3 to 18 T. per hr. Ball load, 28,000 lb. of 5-, 4-, 3-, and 2½-in. balls. Speed, 19.7 r.p.m.

Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part located between them (Fig. 2.12).Such a ball mill body is expedient because efficiency is appreciably increased. Peripheral velocity along the conical drum scales down in the direction from the cylindrical part to the discharge outlet; the helix angle of balls is decreased …
