    The batch mill used has a diameter and length equal 254mm and eight charge lifters equally spaced. It was operated with a ball charge equal to 20% (J=), powder filling (voids between the balls) equal 50% (U= ) and ran at 70% of the critical speed. The breakage parameters were determined by Austin BII method (Austin et al., 1984). Five narrow size fractions were .

  • What is Void Fraction

     · The local void fraction refers to that at a one single point or very small volume. Therefore it takes the values of 1 or 0. For further purposes, we will assume a void fraction to be the fraction of the channel crosssectional area that is occupied by the gas phase ( crosssectional void fraction) defined as: The void fraction is of importance is the twophase flow, .
