involve grinding). With Lloyd's ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyd's research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.

motor power to drive ball mill To match a ball mill size and its motor size, some math is required. The power requirement calculated above is the motor power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution.

•Decreasing the SAG mill diameter by 2 feet from 36 to 34 ft. causes a 2 MW reduction in installed SAG power or an 18% decrease from 11 to 9 MW. This energy can reduce grinding capacity by about 9%, considering the ball mill if it also has 11 MW of installed power.
