I have accomplished a similar continuous mixing task (albeit on 8 different solid raw materials plus one liquid raw material) utilizing a twin-screw extruder with the solid premix fed via a volumetric or gravimetric screw feeder, and in combination with a gravimetric liquid pump/dispensing assembly feeding also at the feed port. The final process equipment arrangement is dependent upon how many raw materials and teh nature of their respective bulk handling properties, but the layout of the proper equipment and control scheme will provide for a very flexible and efficient process arrangement. ■

Yes. There are numerous types of mixers to set up inline mixing...for ceramic-type slurries, a Pug Mill, for example; for liquid/solid polymer blends - various types of extruders exist. There are many other types of continuous [inline], continuous-batch [inline], or batch mixing processes [mulit-stage processing]. It is difficult to specify an efficient mixing process without more knolwedge of the raw materials, the degree of mixing intensity required (i.e., low intensity mixing with the raw material powders already at size vs. high intensity mixing with size reduction of the solids) and the upstream/downstream processing. My best guess, for what you describe - mixing mud with water - might best be a Pug Mill. ■

After reviewing the original post, a Pug Mill would not typicaly be used for inline mixing of concrete admixtures; same for the mud:water "slurry". A Pug Mill mixes much higher viscosity ceramic mixtures to produce a blank for forming greenware, not for slurries. A static in-line mixer, or semi-batch/continuous impeller [vessel or container] mixer could be used for mixing liquid admixtures before dosing to concrete batch. ■
