colloidal grout mixer pump

The Colloidal Grout Mixer Pump Unit is a compact grouting system developed for the preparation, storage and controlled delivery of cement-based and bentonite-based grout. By integrating a high-shear colloidal mixer, an agitating tank and a grout pump on one working platform, the unit provides a practical solution for contractors carrying out borehole injection, micropile grouting, foundation reinforcement and ground improvement work.

A complete colloidal grout mixing pump unit integrates high-shear colloidal mixing and pressure grouting pumping into a mobile or stationary system. It is used to produce and inject cement, chemical, or polymer grouts into rock fissures, soil pores, tunnels, and structural voids.

A small colloidal grout mixer with agitator is a compact, high-efficiency mixing system designed for preparing stable, homogeneous grouts—especially those requiring full hydration of bentonite, cement, or chemical additives—in small- to medium-scale ground engineering, piling, and grouting projects.

A colloidal grout mixer is a specialized type of grout mixer that uses high-speed shear mixing to produce ultra-fine, homogeneous grout mixtures. It is ideal for applications requiring smooth, lump-free grout, such as injecting microfine cement, chemical grouts, or resin-based materials into fine cracks, soil fractures, or rocky formations.

The working principle of continuous colloid cement mixing pump usually involves the following steps:
Material input: Cement, water and other raw materials are input into the mixing chamber in a certain proportion.
Mixing process: The agitator or impeller in the mixing chamber starts to rotate to fully mix the materials.
The specially designed mixing chamber structure helps to ensure uniform mixing of materials.
Conveying process: The mixed colloid cement is continuously conveyed to the designated location through the pump body.
The pump body is usually driven by hydraulic or pneumatic pressure to ensure stable conveying pressure.

Colloidal grout mixer pump can be used for bentonite suspensions for micro tunneling, pipe jacking, and directional drilling.
