bulk densities of grinding aid

Impact of grinding aids on dry grinding performance,

2018-2-1  For the grinding experiments, calcitic limestone Durcal 40 (98% CaCO 3) by Omya, Switzerland with a median particle size of x 50 ≈ 20 µm was used. Solid and bulk densities of this material are ρ S = 2.73 kg/L and ρ B = 1.074 kg/L, respectively.
