ChemGrout’s CG-600 heavy-duty, high volume colloidal grout plants are claimed to have provided the tunnelling industry with the standard for both water cut-offs and back-filling since 1963. The series is said to combine the latest advances in colloidal mixing with ChemGrout’s patented 3L6A pump, providing outputs of up to 20 gpm (75 lpm) and 261 psi (75 bar).
These grout plants feature a 13 cu ft capacity “Turbomixer”, along with a rotating bridge breaker, 13 cu ft capacity vertical shaft paddle agitator, and a three-stage, size 6, closed throat progressive cavity pump. Mixer and pump are mounted on a single skid “for quick, easy set-up and immediate operation”.
Water and solid materials are drawn through a diffuser type pump rotating at speeds of up to 2000 rpm to prevent flocculation and achieve complete particle wetness. Mixing time is said to be significantly reduced by the high shear action of the colloidal mixing pump, aided by a powered bridge breaker device to enhance induction.
Says ChemGrout: “These high shear colloidal mixers have been shown to increase apparent fluidity of slurry mixes by 20 per cent over paddle mixers, an important advantage for rock and soil grouting where the ability to penetrate tight formations is necessary.”
The colloidal series comes in several mix tank sizes with power options that include air, hydraulic, electric and diesel/hydraulic.
