Selection of mill balls has to made based on the following factors 1 Material of mill balls has no impurity to grinding materials 2 Properties of balls material such as anti high temperature wear resistance and corrosion resistance have to meet request of grinding process
The grinding rate constant is one of the important factors needed to measure or evaluate a grind ing process. It has been found that the decreasing rate of the feed sie is described by a first-order equation in the initial grinding stage of various mill types. In this study we conducted grinding tests on silica glass using a ball mill and
