Size segregation of bidisperse granular mixtures in rotating drum
网页2020年9月1日This parameter is significantly affected by the mixing and segregation state of the impacting media and the powder. Typical efficiency of a ball mill is 1 to 5%, i.e., only a small amount of supplied energy is used for breaking the particles [14]. This can be improved by a better understanding of the phenomena involved in the milling process.

A Review of Breakage Behavior in Fine Grinding by Stirred-Media Millingt
网页media, there is a tendency for segregation of the media in the mill. At a low rotational speed, the media tend to settle, leading an inhomogeneous distribution of media. On the other hand, at higher rotational speeds, a vortex is formed and the media are concen trated at the wall due to centrifugal forces. Therefore,

Size Distribution of Grinding Media (Balls) in a Mill
网页2011年3月21日At high speed, they are in the centre. This applies to all types of grinding media, e.g. pebbles, ball or rods. This segregation is a result of the fact that at low speed, the force of gravity is stronger than the centrifugal force, so that the grinding media move around the core of the charge.
