Oct 05 2006 for ball milling you need the bond ball mill work index units are kwht knowing the bond work index and the feed and product sizes you can calculate the power input required if you post more detail about the application and ore we might be able to predict performance using values from similar ore types cheers
Power scale up is accurate because power is measured as power consumption at the agitator shaft to determine the specific energy requirements and size the mill and psd scaleup is accurate because of the horizontal isamill layout which eliminates any short circuiting and the classifying action of the product separator
