Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a constant cascading of media at the surface. Because the media is falling the fastest and for the longest distance at the top of the pile, the majorityThat's exactly what you must avoid unless you don't mind the ball mill experiencing as much damage as the charge, and an end product that has been reduced to fine dust. The maximum ball size I ran was 2", along with an assortment of smaller balls, down to about 3/4", along with a number of rollers from a large bearing.

How does ball mill rotating speed influence grinding ... Request PDF on ResearchGate | Effect of Ball Size and Powder Loading on the Milling Efficiency of a Laboratory-Scale Wet Ball Mill | Alumina powder was wet-milled by zirconia balls with varying diameter at varying rotation speed, and the resultant particle size of the milled powder was analyzed.Milling says : Avoid interrupted cuts. An interrupted cut is one where the tool alternately enters and leaves the workpiece during the cut. Because cast iron has relatively low tensile strength, the tendency of the cutting forces it to break out the edge of the casting as the tool leaves the work.
