Feed Size VS Ball Size - Grinding & Classification Circuits .Apr 4, 2018 . Does anyone have a chart to know if there is any relation between the feed size and the size of the ball needed to grind the ore in SAG and Ball mills?what is the feed size for 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.

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.

Effect of ball and feed particle size distribution on the milling .

In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material. The experimental parameters that were kept constant in this investigation.

The Effect of Ball Size Diameter on Milling Performance | OMICS .

The 30 mm ball diameter milling still performed better than the small ball diameters, but the performance for this ball size had decreased for the -2 mm +1.4 mm mono-size feed compared to the bigger -4 mm +2.8 mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller.
