For rod, ball, or pebble mills the peak is usually near Vp = .50, while actual observations as low as V= .42 have bean made in some ball mills (Rowland, 1973). See Figure 2. Power draw is not significantly affected by the presence of the slurry in the mill.
There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:

I'm interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if

Capacity (tons) China: 2.3mill: North America: 700,000: South America: 750,000: Europe: 500,000: Russia & CIS:
Load torque calculation for rotary index tables uses the same formulas as a belt drive, but it requires a slightly different thought process to determine the necessary variables.In this case, friction occurs at points where the ball rollers (support bearings) and the table make contact, so radius (r) will be the distance from the center of the motor …
The impact breaking force, the grinding capacity and the ball mill capacity are relative with the size of steel balls. The experiment results show that, at the same amount, the size of steel balls is in direct proportion to the impact breaking force, the grinding capacity and the ball mill capacity.
SAG mill liner change-out life/cycle vs. tons/kg consumed. Ball mill liner efficiency based on liner geometry and its influence on kW-hours/ton, total tons/life cycle, and P80 transfer to cyclones. Ball mill grind is based on different principle; it has some attributes similar to SAG mill optimization.
