colloidal grout plant

The High-Shear Colloidal Grout Mixer Pump Unit is a piece of high-efficiency grouting equipment specifically designed for cement-based grouts. Utilizing a high-speed rotating high-shear impeller or centrifugal dispersion device (operating at speeds of 2,000–3,000 rpm), it thoroughly disperses materials such as cement and fly ash into their finest particles, ensuring complete wetting. This process significantly enhances grout stability while minimizing the risks of bleeding and segregation. These units are widely used in heavy-duty construction applications—including dams, tunnels, post-tensioned prestressing projects, underground mining, and geotechnical anchoring—and are compatible with various grout materials, such as neat cement grout, bentonite slurry, and micro-cement grout.

The Colloidal Grout Plant for Micropile Injection integrates high-speed mixing, storage, continuous agitation, and pressure injection capabilities, enabling the continuous supply of uniform, stable, and highly pumpable cement grout for micropile construction.
Micropiles are characterized by small diameters, construction flexibility, and strong site adaptability; they are widely used in building foundation reinforcement, bridge maintenance, slope stabilization, underground space renovation, and construction in confined areas. Micropiles typically form load-bearing structures through processes such as drilling, the installation of steel bars or pipes, and cement grout injection, where the quality of the grout directly impacts the integrity of the pile and the bond between the reinforcement and the surrounding ground.

In underground mines, grout mixing equipment is a key piece of equipment used to prepare grouting materials. It mixes solid materials (such as cement, loess, fly ash, etc.) with water in a certain proportion to form a uniform slurry that meets the required concentration, which can be used for mine fire prevention and extinguishing, goaf backfilling, roadway reinforcement and other projects.
