Method for producing dispersions of a defined particle size

Method for producing dispersions of a defined particle size, wherein a mixed dispersion is continuously separated into a coarse fraction dispersion and a fine fraction dispersion, comprising the following steps:

• A) continuously or discontinuously producing the mixed dispersion in a predispersion process, in that a particle mixture of a disperse phase is mixed with a liquid continuous phase to form the mixed dispersion and is temporarily stored in at least one mixing tank,
• B) introducing the mixed dispersion from the predispersion process into at least one continuously operating separating device,
• C) separating the particle mixture of the mixed dispersion in the at least one separating device into coarse particles (Pg) of the coarse fraction dispersion and into fine particles (Pf) of the fine fraction dispersion according to a threshold value for the particle size,
• D) discharging the fine fraction dispersion from the at least one separating device into at least one storage tank,
• E) discharging the coarse fraction dispersion from the at least one separating device into at least one disperser,
• F) crushing the coarse particles (Pg) of the coarse fraction dispersion in the at least one disperser into a dispersed particle mixture (PDm), and returning the dispersed particle mixture (PDm) into the at least one mixing tank in the predispersion process, and
• G) mixing the dispersed particle mixture (PDm) returned to the predispersion process with the mixed dispersion produced in the predispersion process in the at least one mixing tank.
