grout unit for backfill

Bentonite compaction cement colloidal backfill grout mixer is a mixing equipment for grout injection in the fields of foundation engineering, soil reinforcement, tunnel construction and excavation. The equipment is mainly composed of mixing tank, conveying system, electric control system, hydraulic system and other parts.

Bentonite compaction cement colloidal backfill grout mixer can mix cement, mortar, bentonite and other materials into a viscous liquid, so that it can form a solid connection between the soil and stone that need to be consolidated. The equipment has the advantages of automatic control, high efficiency and energy saving, convenient movement and easy operation, etc., and can meet the precision and time requirements in construction.

Backfill grout batching plants is a combination of agitator, agitator, and grout pump in one piece of equipment. The special mixing effect of cement or bentonite with water is achieved in the mixer by the high turbulence generated in the pump housing. This turbulent flow with high shear forces separates cement or bentonite particles, resulting in a fully hydrated suspension.
As soon as the mixing process is over, the mixture is transferred to the agitator. A slow stirring paddle prevents the grout from settling out of the suspension and removes any air bubbles in the mixture. Each machine is equipped with a mixer and pump with matching capacity, plus a mixing tank that allows for almost continuous operation once work begins.
