CG - 680 Hydraulic Powered Shown

The ChemGrout CG-680 series includes both skid and trailer mounted equipment.  The colloidal series easily mixes and pumps slurries of cement, fly ash, bentonite and lime flour.  Each grouting machine in this series is designed to provide a continuous mixing and pumping operation.   These units feature a 17 cubic foot high shear colloidal mixer, a 17 cubic foot agitated storage tank and a 45 GPM grout pump.  The colloidal mixer is equipped with a high speed centrifugal diffuser-type pump that disperses the cementitous 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 agitated storage tank is equipped with a variable speed high-efficiency paddle mixer that maintains a thoroughly mixed grout while waiting to be pumped.  The grout pump is connected directly to the agitated storage tank to provide a continuous pumping operation.  The grout pump is a 3 stage, size 8, progressing cavity, positive displacement, rotor-stator pump.  The rugged steel frame stands up to the toughest conditions on the construction site.  Operator controls are centrally located for efficient production.  All components are easily accessible for operating, cleaning and maintenance.

Applications include: tunnels, mining, dam foundations, soil compaction, soil & rock grouting, waterproofing, soil anchors, rock bolts, encasements, and post tensioning
