Ball MillDesign. A survey of Australian processing plants revealed a maximumball milldiameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

The high unit capacity SAGmill/ball millcircuit 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).

Mill Steel Charge Volume Calculation
Mill Steel Charge Volume Calculation

We can calculate the steel charge volume of aballor rodmilland express it as the % of the volume within the liners that is filled with grinding media. While themillis stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of themill. The % loading or change volume can then be read off the graph below or ...

Add to this another 45% to 50% above the ball charge for total of 58% to 63% product loading. This level of liquid loading should leave some air space above the liquid to allow for expansion of the liquid as it heats up during the milling process. So as a rule of thumb we use a maximum of 60% liquid loading. See our Size Reduction Options

If you were to opt for something a little larger or with a digital readout, you could easily spend $1,000 on a micromill. If you're shopping for an entry-levelminimill– also known as a drilling/milling machine – you'll need in excess of $2,000. For a floor-standing milling machine, expect to spend $5,000 or more.
