Fractionation of pulp and paper particles selectively by size

effect of occ pulp fractionation on paper properties

this study sougth to the effect of occ pulp fractionation on produced paper strength properties improvement. using a pressure screen, occ pulp was devided to tow distinct fractions of accept ratio (short fibers) and reject ratio (long fibers) in accordance with optimum condition of fractionation based on the previous studies. in the next stage, long fiber stream was refined and recombined with ...

Particle size fractionation of soil containing coal and combusted particles

Standard procedure for dispersing natural soils for particle size fractionation can be too aggressive for soil containing coal and other organic particles from coal industries. We have investigated ultrasonic dispersion for the latter in four soils differing in pedogenesis (Phaeozem, Podzol, reclaimed mine soils), carbon content (27.5±138.6 g kg), clay content (80±153 g kg) and sources of parti...
