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.
Notes on Ball Mill Design - Power Draw. Power Draw is steady running power requirement ... ignoring drive-train losses and startup loads. Power Draw is reduced for regrinding ... ie. if 1.5 ; (Feed Size/Product Size) 3.0
Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation.
In the case of ball mills, this is certainly not straightforward. Let´s consider a simple example: the most common tumbling mill test used in the lab is the Bond ball mill grindability test, used for nearly 70 years to determine the Bond work index, which is a number used to estimate how hard it will be to grind the material of interest.
