    Abstract Size reduction is the operation carried out for reducing the size of bigger particle into smaller one by external forces. This reducing in size is done by using ball mill. In the experiment, the stone are weight about 100g and mix with two handhelds of grinding ball into the ball mill. The speed control knob is adjusted each at 40 rpm and 90rpm

    Effect of lifters and mill speed on particle behaviour

    May 01, 2017 Fig. 10 shows the power of the ball mill, which is determined by using different methods with varying mill speeds. In this study, the experiment result is selected as the standard power. When the fill level is 35%, the ball mill works at a low-speed zone when ψ ⩽ 68 %, and when ψ 68 %, the ball mill works at a high-speed zone
