| Abstract: | Three-product separation experiments were carried out with model materials and coarse coal particles in the fluidized bed. In the separation region of low density, the partition density is around 1.52 g/cm3' with probable error E. of 0.08. In the separation region of high density, the partition density is around 1.87 g/cm' and Ep value is about 0.11. |
