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.
