Size segregation of bidisperse granular mixtures in rotating

Sep 01, 2020 · 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 . This can be improved by a better understanding of the phenomena involved in the milling process.

A novel approach of evaluating crushing energy in ball

Oct 01, 2019 · In order to observe the axial segregation phenomenon in the ball mill, a simulation model is established based on discrete element method. The ball mill is simplified as a transparent cylindrical drum which contains a large number of balls as the grinding medium to observe the axial distribution of balls more intuitively.
