This unique batch plant is used to produce cementitious slurry for use in ground stabilization. The main components of the plant comprise of a cement silo and screw conveyor, Bentonite feed system, four mill colloidal mixer, agitation tank, dust collecting system, PLC control system, motor controls, and progressive cavity pump.

Slurry is automatically produced in the colloidal mixer upon demand and stored in the agitation tank. Here it is discharged at a controlled rate as required by the crane operator. The crane may be several hundred feet from the plant. The crane lowers large augers into the ground to be stabilized, mixing the soil with incoming slurry piped from the plant. Radio controls provide the crane operator with both a digital readout of the slurry flow rate and flow adjustment control. As the slurry agitation tank is drawn down, additional batches are called automatically.

Cement is delivered into the silo pneumatically and bentonite is delivered either in hand bags or bulk bags. Following each batch, water is reweighed and the mixer and slurry discharge lines are purged clean. This water remains in the mixer (scale), ready for use in the following batch, minimizing water wastage.

The grout plant and crane are both relocated throughout the country, to ground stabilization job sites for relatively short periods of time. Team Mixing Technologies is again proud to have worked with an industry leader in another leading edge technology.
