colloidal-grout-mixer is a skid mounted, colloidal grout unit. This system is designed to provide a continuous mixing operation. This unit features a 13 cubic foot or 17 cubic foot colloidal mixer and a 13 or 17 cubic foot agitating holding tank. The colloidal mixer is equipped with a high shear centrifugal mixing pump that breaks the material down to its finest particle size to achieve complete particle wetness. The mixing tank is also equipped with a bridge breaker to break apart the material before entering the colloidal mixer. The agitating holding tank has a vertical shaft with horizontal blades that are in constant contact with the material to maintain a thoroughly mixed grout. There is no grout pump on this unit. All components are easily accessible for operating, cleaning and maintenance.
