Claims (1)

[Claims for Utility Model Registration] (1) A rotating chute for receiving and passing a lump, granular or powdered sample supplied from a feeder; The rotary chute includes a plurality of reduction tanks that receive and reduce the sample supplied from a rotary chute, and a driving means for rotating the rotary chute around the rotation axis; The reduction tank has a hollow inner cylinder and an inclined part that communicates with the opening, and an outlet provided at the lower end of the inclined part and opens to the reduction port of the reduction tank; an outer cylinder arranged concentrically with the cylinder and forming an annular space between the inner cylinder; and dividing the annular space in the circumferential direction;
a plurality of partition plates defining a plurality of reduction tanks; a lumpy, granular or powder sample characterized in that the top of the reduction tanks is close to the outlet of the rotary chute; reduction machine. (2) The plurality of partition plates include a pair of fixed partition plates disposed substantially perpendicularly at circumferentially opposing positions on the outer wall of the inner cylinder, and a pair of fixed partition plates arranged at inclined positions on the circumferentially opposing positions of the inner wall of the outer cylinder. It consists of a pair of movable partition plates, and a scattering/contamination prevention plate that is in contact with the movable partition plate at its top and is disposed at an opposite slope to the movable partition plate, and the movable partition plate and the scattering/contamination prevention plate are arranged at an angle opposite to the movable partition plate. Claim 1 of the Utility Model Registration Claim, characterized in that by rotatably arranging the plate, the opening area of the reduction port opening toward the lower end of the reduction tank can be arbitrarily changed. Reduction machine for bulk, granular or powder samples. (3) The discharge port of the rotary chute is characterized in that a part of the rotary chute is comprised of a movable plate that is hinged at a portion of the rotary chute, and that the movable plate is movable by contact with the falling sample. A reduction fractionator for lumpy, granular or powdered samples according to claim 1 or 2 of the utility model registration claim.
