grinding void volume mill Prenataal Screenings Centrum

In order to calculate the maximum volume of grinding zones in the mill, we assume that each media particle has twelve nearest neighbours (upper limit for hexagonal close-packing (HCP); a lower number will apply in practice) and calculate the maximum total volume of grinding zones in the mill as a fraction of the void volume between the media
