Zusammenfassung:	PCT No. PCT/FI96/00140 Sec. 371 Date Nov. 24, 1997 Sec. 102(e) Date Nov. 24, 1997 PCT Filed Mar. 7, 1996 PCT Pub. No. WO96/27443 PCT Pub. Date Sep. 12, 1996A method and apparatus for grinding granular solids in liquid slurry form within a mill. The solids density of the feed slurry is maintained below the solids density in the mill, thus causing the liquid to flush through the mill, preferentially carrying and discharging finer relative to coarser particles. Discharged solids thus have a smaller concentration of overground solids, and grinding capacity and power consumption by the mill are optimized.
