Optimum choice of the make-up ball sizes for maximum throughput 27 jun 2013 the ball size is one of the critical factors for determining the mill performance become too large to be broken efficiently by the grinding media.
In the case of ball mills, this is certainly not straightforwardets 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.
During the proposed 18 year life of the mine the mill design was then made with consideration for the estimated amount of sample testing data to the hardness estimate of each block of ore in the mine plan the final design grinding plant design the plant design was conducted using alculates the grinding charge of a ball mill mining.
