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.

Calculate and Select Ball Mill Ball Size for Optimum Grinding
4/8/2021· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

rate at each screen size is calculated from a torquemill test as in the example that follows. Torque mill solids load during test: kg ( lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: rpm (65 percent of critical speed)
