Method for producing aggregates and method for producing powders and granules

Abstract

To provide a novel method for producing aggregates of polymer fine particles which can provide powder granules having a low fineness ratio.SOLUTION: There is provided a novel method for producing an aggregate which comprises a first contact step of spraying and / or dropping a latex of polymer fine particles in the vertical direction and spraying a coagulant solution in the horizontal direction or a second step of spraying and / or dropping the coagulant solution in the vertical direction and spraying the latex in the horizontal direction, wherein in the second contact step, the horizontal distance between the nozzles is longer than the vertical distance.SELECTED DRAWING: None
