摘要： The aggregated particles are manufactured through a method of manufacturing aggregated particles, which includes an aggregating step, a depressurizing step, and a cooling step. In the aggregating step, a slurry is prepared which contains aggregated particles obtained by flowing an aqueous slurry of resin fine particles having a volume average particle diameter in the range of 0.4 μm to 3 μm through a coiled piping in a heated and pressurized state and thereby aggregating the resin fine particles. In the depressurizing step, the slurry containing the aggregated particles is depressurized, and a particle size control is conducted by disintegrating coarse particles so as to homogenize particle diameters of the aggregated particles. In the cooling step, the slurry containing the aggregated particles of which particle diameters have been homogenized is cooled.

摘要： There is provided a method of manufacturing coalesced resin particles for obtaining coalesced resin particles by coalescing aggregated resin particles in a grain boundary-free state in a short period of time while keeping a grain size distribution within a narrow range. In a coalescence process, a slurry of aggregated resin particles is flowed through an inside of a pipe under predetermined heating and pressurizing conditions. In a before-cooling decompression process, a slurry of coalesced resin particles flowing through the inside of the pipe in a heat and pressure-applied state is subjected to pressure reduction before it is cooled down to a predetermined temperature in a cooling process. Then, in a decompression process, a coalesced resin particle slurry that has been cooled in the cooling process while being flowed through the inside of the pipe is decompressed to an atmospheric pressure.
