sag mill design calculations
Stopping mill equipment is not a desirable alternative, so the best way to resolve SAG mill challenges is to use simulation technology for equipment design alterations. Replacing the SAG's worn-out liner can occur every six to nine months and cost between $30,000 U.S. and $200,000 U.S. per hour, and each repair takes between 40 hours and 120

SAGMILLING.COM .:. Mill Critical Speed Determination
The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed. Result #2: This mill's

DESIGN OF AG/SAG MILL CIRCUITS USING THE SMC TEST
PREDICTING AG/SAG CIRCUIT SPECIFIC ENERGY USING THE Dwi The power-based approach to design uses a methodology which, given certain ore breakage characteristics, predicts the specific energy for a particular AG/SAG mill circuit. The multiplication of the specific energy by the target throughput gives the required power draw of the mill. A mill
