Abstract
A method for producing dispersions with a defined particle size includes following steps: A) Preparation of a mixed dispersion in a predispersion process, B) introduction of the mixed dispersion into at least one continuously operating separating device, C) separation of the mixed dispersion in the separating device into coarse particles of a coarse-part dispersion and into fine particles of a fine-part dispersion, D) discharging the fine particle dispersion from the separating device into at least one storage tank, E) discharging the coarse particle dispersion from the separating device into at least one disperser, F) grinding the coarse particles of the coarse particle dispersion in the disperser into a dispersed particle mixture and returning the dispersed particle mixture to the mixing tank in the predispersion process, and G) mixing the dispersed particle mixture returned to the predispersion process with the mixing dispersion produced in the predispersion process in the mixing tank.
