The invention relates to a dehydrating centrifugal sieve of small overall dimensions, small weight and big yield. The sieve is appropriated for dehydration, de-sludging, enrichment and classification of mineral grains. The sieve according to the invention has in a common housing (1) several conical sieve elements (2), (12), (13) disposed successively under each other and at the same time inside each other. Between particular sieve elements there are funnels (4) terminated at the bottom with a circumferential gutter (5). The circumferential gutter (5) is connected by pipe passages (6) situated in an offtake (7) of granular concentrate through a flow-off surface (9) with an offtake (10) of clarified liquid.

A dehydrating centrifugal sieve assembly for separating solid particles from liquids, comprising a housing and at least two generally conical shaped sieves in the form of inverted frustum cones mounted in the housing, disposed one below the other and substantially nested one inside the other, each two adjacent conical sieves being separated from each other by a funnel also of an inverted generally conical shape and nested therebetween, each funnel having a bottom center portion with a circumferential liquid collecting gutter, each conical sieve having an upper circumference and having an input nozzle connected approximately tangentially to said sieve adjacent said upper circumference, a particulate discharge conduit means situated in a central bottom portion of each conical sieve and being arranged vertically and interconnected to a single discharge, a clarified liquid discharge means being situated on a radially outward side near the bottom of the housing, each of said circumferential gutters having passage means vertically situated inside the discharge conduit means, and connected with a collecting chamber for the clarified liquids, said chamber being situated under the lowest conical sieve within the housing and above a flow-off surface on a bottom portion of the housing.
