Good flowability of granular solids depends mainly on the container itself rotating, or packed in containers within the moving parts function repeatedly flipping, mixing and mixing, these items also available air convection or turbulence in the mix. Solid particle convection causes eddy currents or turbulence, mixing speeds well below the liquid mixture, mixing only random mixing. Poor mobility, mutual adhesion of granules or powdered solids, is often needed with mechanical turning and pressure, forging hybrid machines. Common mixers are: horizontal PEAR cutter mixer, Ribbon mixer, weightless mixer, v-type mixer, double screw cone mixer
