High Shear Colloidal Grout Mixer for Cement and Bentonite Slurry
The HWM300E, launched by Henan Wode Heavy Industry Co., Ltd., is a high-speed, high-shear colloid grout mixer designed for cement and bentonite slurry preparation. It can rapidly mix cement, bentonite, fine sand, and appropriate additives.
The impeller speed reaches 1450 rpm, and the mixing time for a single batch of slurry is approximately 3 minutes. This helps construction teams reduce slurry preparation waiting time and improves the continuous operation efficiency of grouting equipment. Actual mixing time will vary depending on the slurry ratio, material properties, and on-site process requirements.
Why is high-shear mixing necessary for cement and bentonite slurries?
Ordinary low-speed mixers rely primarily on blades to circulate materials. When processing cement, bentonite, and additive mixtures, this often requires longer mixing times, and fine powders may be difficult to disperse quickly.
High-shear colloid mixing technology uses a high-speed impeller to generate strong vortices and shear forces, allowing cement, bentonite, water, and additives to quickly contact and fully disperse, forming a more uniform and stable suspension.

Five Construction Benefits of Our High Shear Colloidal Grout Mixer:
1. Rapid Slurry Preparation in Approximately 3 Minutes: The shorter mixing cycle reduces grouting pump waiting time, making it suitable for foundation, tunnel, and hydraulic grouting projects with high construction speed requirements.
2. Improved Slurry Uniformity: High-speed shearing helps to fully disperse powder, resulting in a more uniform slurry of cement, bentonite, and water, reducing local concentration differences.
3. Improved Slurry Stability: Thorough mixing reduces slurry settling and bleeding, ensuring a more stable working state of the slurry during storage, transportation, and injection.
4. Adaptability to Various Grouting Materials: In addition to ordinary cement slurry, the equipment can also be used for bentonite slurry, cement-bentonite composite slurry, and engineering slurries containing appropriate amounts of fine sand or additives.
5. Compact Structure for Easy On-Site Deployment: The HWM300E weighs approximately 280kg and has dimensions of 1250×1050×1800mm. The equipment features a simple structure and convenient maintenance, making it suitable for construction environments with limited space or requiring flexible relocation.

What grouting projects is it suitable for?
The HWM300E High Shear Colloidal Grout Mixer can be applied to a variety of surface and underground projects, including:
Dam foundation curtain grouting and seepage prevention;
Tunnel lining backfilling and void filling;
Grouting for subways, shafts, and underground structures;
Foundation reinforcement and soil stabilization;
Micropiles, anchors, and borehole grouting;
Rock fissure filling and mine reinforcement;
Bridge foundations and existing structure repair;
Cement-bentonite waterproofing grout preparation.

For projects requiring continuous construction, a grout storage mixer can be added after the high-shear mixer to keep the mixed grout flowing and uniform, while simultaneously starting the preparation of the next batch of material, thereby reducing equipment downtime.
