Effect of media size and mechanical properties on milling
The effect of mill media material properties on grinding efficiency, media wear, and power consumption was defined. High density media with optimum sizing improved milling efficiency by approximately 30%. Mill media with a low coefficient of As the shapes of the three grinding media are different, in order to keep the same mass different media sizes must be used. Thus the results may only reflect Comparison of grinding media—Cylpebs versus balls

Stirred Mill an overview ScienceDirect Topics
In high-speed stirred mills the effect of mill tip speed, media size and density can be evaluated simultaneously using the grinding media 'stress intensity' approach and an illustration of this is summarised in Fig. 1.5 which shows a plot of product particles size (starting size 45 μm, product size ∼2–6 μm) versus stress intensity for a pin mill using a It was claimed by the manufacture (Doering International) that for a given charge volume, Cylpebs provide 25% more grinding media surface area for size reduction. The grinding performance of the Cylpebs should then be correspondingly higher compared with the steel balls (Doering website: doering-sinn.de ).Comparison of grinding media—Cylpebs versus balls
