Abstract

The invention deals with continuous process mixing of pulverized solids and liquids. It offers a mixing process comprising: continuously introducing a liquid into a mixing container; continuously introducing a solid powder into said container at such a rate that specified proportions of solid and liquid in the mixture are maintained; rotating the products in the container in such a way as to establish a vortex; regulating the solid and liquid supply rate in such a way that a given level of filling of container is constantly maintained; continuously emptying the products mixture so that level of filling is maintained. It offers as well a mechanism to implement the process including a mixing container having an intermediate bottom and a runoff opening, a turbine mounted above the intermediate bottom, and mechanism for supplying a liquid and a solid. Advantageously, the liquid is used to wash down the walls of the mixing container and may be applied to parts of the turbine to avoid retention of solids in the container. It can be applied to hydraulic binders preparations and specifically to continuous process preparation of a plaster and water mixture.
