Abstract (en)

The present invention discloses a centrifuge that is not only suitable for a highly selective classification of fine-grained solids in very small increments, but can also be used for carrying out a sorting process and a classifying process simultaneously in one and the same machine so as to separate solid impurities from the fine grain to be obtained. According to the invention, a sorting zone (A) and a classifying zone (B) are integrated into this centrifuge, wherein the sorting zone (A) extends from the immersion disk (18) to the floats discharge (20) at one end of the centrifuge, and the adjacent classifying zone (B) extends from the immersion disk (18) to the sinks discharge (23) at the other end of the centrifuge. In this case, the coarse-grained solid (24) is discharged at the sinks discharge (23 or 26), while the fine-grained solid (25) is discharged from the centrifuge with the suspension fluid as a third phase. <IMAGE>
