This self-contained high volume dry mix unit produces the slurry (portland cement type I and water) on-site. The slurry is combined with pre-formed foam during the mixing process. Its special design progressive cavity pump has gentle pumping action "minimizing cellular breakdown" producing high pumping pressures and output rates at low rpm. The proportions of cement, water and foam are calibrated to achieve required densities. The ratio of slurry to foam determines the Pound-Force per Cubic Foot (PCF) of the product. The silo stores the cement which is then augered into the weight batch hopper, then transferred to a mixing chamber where water and foam are added. After material is completely mixed, it is transferred to the pump hopper and pumped through a 2” grout hose while the next batch is being produced. This allows for continuous production. This unit has successfully completed many high profile projects.
