Grout mixing machine for consolidation grouting in dams
This grout mixing machine for consolidation grouting in dams will continuously mix and pump the widest range of grouting materials from thin to thick consistencies. Materials that are used with this unit include Repair Mortars, Gel Mortars, Stucco, Fireproofing Plastering, cement/masonry sand, cement/fly ash, flowable and non-flowable grouts and bentonite waterproofing grouts. The optional air compressor allows the operator to continuously mix, pump and spray. The 850 mixing tank is equipped with baffles, bag breakers and variable speed high-efficiency paddles that provide rapid mixing. The unique mixing action allows rapid mixing and pumping of grouts containing sand, up to a sand/cement ratio of 4:1 and neat cement grouts with water/cement ratios as low as 0.36:1 without additives, or lower with plasticisers or super plasticisers. The mixers are also very efficient at mixing bentonite and other clay products as the process accelerate hydration and make a more stable product.
The range of mixers as detailed below cater for outputs from 1.5 to 8 cubic meters per hour as batch mixers, dependent upon mix design and material feed rated. Alternative pump rates can be specified if required.

Features of grout mixing machine for dams:
1. High mixing efficiency, motor directly driving impeller to get the high-speed liquid flow, about 2~3minutes to complete a mixing;
2. High reliability, vertical-mount motor, easy to seal, low failure rate and good seal;
3. Adopt the ordinary rubber pipe as consumable part for control valve, easy to get it on construction site;
Grout mixing machine for grouting is a skid mounted, colloidal grout unit. This system is designed to provide a continuous mixing operation. It is a combination consist of a steel sheet cylindrical mixer tank, heavy-duty slurry pump, and agitator tank, set-up on a strong base frame. For the power, also there is diesel engine motor for option. The water, cement and bentonite are mixed through a high speed vortex produced by a special pump. As soon as the mixing process is over, the mixing is transferred into the agitator. The slow stirring paddle prevents the grout from settling out of suspension and removes any air bubbles from the mix. Mixer and agitator is switch by using butterfly valve.
