METHOD OF SIZING POLYDISPERSE MATERIALS IN LIQUID MEDIA Russian patent published in 1999 - IPC

Abstract RU 2130806 C1

FIELD: powder technology. SUBSTANCE: abrasive suspension stream is passed at specified velocity in direction inverse to force field direction. Separation is carried out in centrifugal force field as follows: fine fraction stream is freed from material and remaining liquid stream is combined with coarse fraction stream and returned into separation stage. Process is circuited with respect to liquid streams and is resumed until complete separation into coarse and fine fractions. EFFECT: achieved automatic-mode accurate and intensive sizing of materials over a large size range. 1 dwg
