ABSTRACT:
The inventive method uses a continuous mixer for making dispersions or suspensions of a solid phase in a liquid phase. The solid and liquid phases are fed continuously into the mixer at respective input rates resulting in a combined proportion of solid phase to liquid phase. The combined phases are continuously formed into a third phase as a plastic-consistency layer extending all around the mixing region. The third phase is thick enough in its plastic consistency for continuously receiving the solid and liquid phases and preventing their passage through the mixing region until they are homogeneously mixed together. The third phase is thoroughly mixed until it changes from its plastic consistency to a substantially more flowable fourth phase capable of continuous output flow from the mixer.
