Abstract
Abstract An apparatus for subdividing a mass of small particles into a plurality of sub streams of relatively variable size comprising two disc-shaped members which between them define an interspace, and at least one of which rotates at high speed. The mass of particles is introduced at the centrum of the interspace and slung outwardly by centrifugal force into the interspace with substantially uniform peripheral distribution about the circumference of the disc-shaped members and into a circumferential annular chamber which is subdivided into sections by means of peripherally displaceable collecting shields; the length of the arc shaped sections being adjustable relative to one another determine the relative magnitude of the sub stream caught in each section by its associated shield which stream is discharged through an opening formed in the circular outer wall of the respective section.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
Apparatus for subdividing a mass of particulate material into a plurality of streams of relatively variable magnitude, comprising: a. a pair of rotatable disc-shaped members defining an interspace therebetween; b. means for rotating at least one of said disc shaped members; c. means for admitting the particulate mAterial into said interspace; d. means disposed in said interspace for radially dispersing said particulate material about the circumference of said disc shaped members by centrifugal force; e. an annular chamber defined between the periphery of said disc shaped members and an outer annual wall for receiving the dispersed material; f. said outer annual wall comprising a plurality of overlapping sections peripherally displaceable relative to one another and each having a discharge outlet; and g. a shield fixed to each of said wall sections adjacent each of said discharge outlets and extending across said annular chamber in relatively movable contact with said disc shaped members to define a plurality of relatively adjustable annular chamber sections.
Claim 2
Dependent Claim
162 words
Apparatus for subdividing a mass of particulate material into a plurality of streams of relatively variable magnitude, comprising: a. a pair of rotatable disc-shaped members defining an interspace therebetween; b. means for rotating at least one of said disc shaped members; c. means for admitting the particulate mAterial into said interspace; d. means disposed in said interspace for radially dispersing said particulate material about the circumference of said disc shaped members by centrifugal force; e. an annular chamber defined between the periphery of said disc shaped members and an outer annual wall for receiving the dispersed material; f. said outer annual wall comprising a plurality of overlapping sections peripherally displaceable relative to one another and each having a discharge outlet; and g. a shield fixed to each of said wall sections adjacent each of said discharge outlets and extending across said annular chamber in relatively movable contact with said disc shaped members to define a plurality of relatively adjustable annular chamber sections.
Claim 3
Dependent Claim
35 words
The apparatus as claimed in claim 1, in which said disc shaped members comprise a lower disc element supported by a vertical, rotatable shaft and a superimposed disc member which together define the annular interspace.
Claim 4
Dependent Claim
29 words
The apparatus as claimed in claim 2, in which the upper disc member is stationary and has a central opening for introducing the mass of particles into the interspace.
Claim 5
Dependent Claim
31 words
The apparatus as claimed in claim 1, in which at least one of the disc shaped members is formed with ridges distributed about the circumference and intervening grooves of curved shape.
Claim 6
Dependent Claim
26 words
The apparatus as claimed in claim 1, in which the outlets of the sections of the annular chamber are adapted to be connected with suction fans.
