Optimum choice of the make-up ball sizes for maximum throughput .Abstract. A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.feed size ball mill,How can one select ball size in ball milling and how much.If the powder is feed for milling then smaller ball size is preferred for homogeneous mixing and milling by avoiding local impact between the balls. There should be atleast 25% empty place in the milling jar after feeding balls and the material while high energy impact. There is no such thumb rule for powder to ball ratio.Ball Mill - RETSCH - powerful grinding and homogenizationRETSCH's innovative Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding down to the nano range. . Mixer Mill MM 200. Feed material: hard, medium-hard, soft, brittle, elastic, fibrous; Material feed size*: ≤ 6 mm; Final fineness*: ~ 10 µm; Setting of vibrational frequency: digital, 3 - 25 Hz.
