• ### Advanced Controller for Grinding Mills Results from a

The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the cyclone is returned to the ball mill. Balls are added periodically to the mill on a per shift basis or when

• ### Supervisory expert control for ball mill grinding circuits

Apr 01 2008 Hence this condition generates an increase in the solid circulating load to the mill feed because a larger portion of the solids goes to the underflow. Then the discharge from the mill slowly becomes coarser and consequently the hydrocyclone overflow particle size becomes coarser until the operation stabilizes at a particle size slightly .

• ### PDF Energy Efficient Ball Mill Circuit Equipment

Ball mill size and power selection As discussed previously ball mill circuit capacity could be increased by around 20 if cyclones are replaced with screens operating at high classification efficiency of 90 and low circulating load of 100. This means that a ball mill selected in Step 1 of the designselection process would have 20 higher .

• ### Ball Mill Circulating Load Mineral Processing amp Metallurgy

Oct 09 2015 The circulating loads generated in a typical ball mill cyclone circuit contain a small fraction of bypassed fines. The concept that high circulating loads will result in overgrinding can be refuted by regarding increases in circulating load in the same vein as multistage grinding. That is for every incremental increase in circulating load of .

• ### Mill Circuit Cyclones Multotec Classification Cyclones
