the basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, bond work index, bulk density, specific density, desired mill tonnage capacity dtph, operating % solids or pulp density, feed size as f80 and maximum ‘chunk size’, product size as p80 and maximum and finally the type of circuit open/closed
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

the test determines the bond ball mill work index which is used with bond’s third theory of comminution to calculate net power requirements*. various correction factors may have to be applied. w = wi (10/√p – 10/√f) where w = net power consumption in kwh/t
a mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. such comminution is an important unit operation in many processes.there are many different types of mills and many types of materials processed in them. historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
note the z axis setting is different because i am running a lower micro stepping count of 2x to get a little more power to lift the head of the mill. final thoughts. remember, these are just initial values to get you int the ball park. we will need to use a dial indicator and tweak the values to get the most accurate motion. more on that in the
thinner mill liners result in a larger volume inside the mill. this means you can have a higher charge level. using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill.
