Abstract

The invention relates to rotatable sieving apparatus for separating a mixture of at least one fine and one coarse component, comprising a number of sieving-surface (1,2) arranged on the same rotatable shaft (5) one above another and of which at least the outermost ones have the form of a conical mantle the apex of which is directed downward and in which one or more conical collecting vessels for the fine components are arranged under the sieving-surfaces, in which a conical divider (26)with an upwardly directed apex is arranged in the centre of each sieving-surface and in which the supply means for the mixture to be separated is located in the vincinity of the centre with the aid of a height-adjustable inlet-pipe arranged above the conical divider and the diameter of which inlet-pipe is equal to the diameter of the base of the conical divider. This type of sieving apparatus has as special characteristic that each sieving-surface is subdivided into an annular centre portion(1) in the form of a conical mantle-surface with an upwardly directed apex which follows up the divider(26) radially and with a reversible direction-of-rotation (d1) and an independent continuously-regulatable angular-velocity(w1) and a number of concentric members (2) arraranged to extend radially outward one outside of another each having the form of a truncated conical mantle the apexes of which are directed downward and each of which has a reversible direction-of-rotation(d2,dn) and an independent continuously regulatable angular-velocity(w2dn).
