Optional equipment: the mill stops working when the hopper is empty. Stone mills are ideal for grinding any type of grain, rice, corn, chestnuts, herbs, etc. Easy to clean
The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ... short-range low-energy impacts within the tumbling charge are ... tracked by the feedback of impact sound from microphones mounted close to the mill. If mill speeds are increased above
Low-competency ores such as oxides are unlikely to have a problem with generation of pebbles. They are more likely to have a problem with slurry viscosity. For smaller plant in the 1980s, these ores were treated through a single-stage SAG mill grinding to 75 or 106 μm. This type of circuit is still straightforward in its design concept.
