AGGREGATE BREAKAGE METHOD AND DEVICE FOR PASTE

PROBLEM TO BE SOLVED: To obtain a paste from which aggregates are removed without generating a waste. SOLUTION: A turntable 2 with an upper surface formed into a flat surface is provided on a base 1 so as to be rotationally driven. A paste inward-feeding blade 3 whose outside end 3b precedes an inside end 3a in a table rotational direction R and a paste outward-feeding blade 4 whose inside end 4a precedes an outside end 4b in the table rotational direction R are disposed each in contact with the surface of the turntable 2 to be supported by a supporting structure 5 so that the paste outward-feeding blade 4 is offset nearer to a table center O. A portion of the paste 6 supplied onto the rotated turntable 2 is made to pass through a sliding part between the blades 3 and 4 and the surface of the turntable 2 while the paste is circulated in a state wherein the paste is raked up by the paste inward-feeding blade 3 to be fed in an inner peripheral direction and a state wherein the paste is raked up by the paste outward-feeding blade 4 to be fed in an outer peripheral direction. Thereby, aggregates in the paste 6 are broken. COPYRIGHT: (C)2011,JPO&INPIT
