High shear speed grout mixer for mixing bentonite

High speed bentonite mixers use a rotating head (e.g., a rotor-stator structure) to generate high shear forces, with shear rates reaching 20,000 to 100,000 s⁻¹, typically at rotational speeds of 10-50 m/s (up to 3,600 rev/min). This shear force quickly breaks down agglomerates between bentonite particles, dispersing them evenly in water to form a colloidal suspension.
In addition to bentonite, the equipment can also process immiscible liquids such as water, cement, and additives (e.g., oil-water interfaces). The multi-directional velocity components (rotational, longitudinal, horizontal, vertical, and radial) generated by the rotating head achieve uniform mixing and reduce droplet size to 2-10 µm.

High shear speed grout mixer machine is a high speed high shear colloidal grout mixer. It has been designed for use either in conjunction with a conventional paddle mixer and pump or, by virtue of its own built in impeller pump, as a stand-alone mix and place machine. The unit will rapidly and efficiently mix various types of grout which can include cement, bentonite and sand.

The 1200L automatic loading high-speed continuous grout mixing plant is a highly integrated and automated mixer equipment designed for efficient and continuous production of high-quality cement slurry.

A colloidal mixer with an agitator is a specialized piece of equipment designed for the efficient and uniform mixing of colloidal suspensions, such as cement-based grouts, chemical grouts, and other fine-particle materials.

High shear speed grout mixers offer high shear efficiency, rapid dispersion, uniform mixing, and anti-sticking properties in bentonite mixing. They can significantly improve the mixing efficiency and quality of bentonite slurries and are suitable for projects requiring high mixing uniformity.

Grouting mixing plant applications: Civil Engineering: Foundation stabilization, tunnel grouting, dam waterproofing. Mining: Sealing fractures, ground control. Geotechnical: Soil compaction, void filling. Infrastructure Repair: Crack injection, slab lifting.

The railway colloid grouting mixer is a special equipment designed for railway projects (such as bridges, tunnels, roadbeds, track slabs, etc.). Its core function is to efficiently prepare highly stable colloid slurry and achieve precise metering, automatic mixing and continuous grouting.

An electric grouting mixing plant is a piece of specialized equipment that mixes cementitious materials (such as cement, fly ash), water, and additives in a certain proportion to form grout, which is then used for grouting operations in engineering projects such as foundation stabilization, tunnel lining, and waterproofing.

The 750L cement grout mixer (with agitator) is a specialized engineering equipment designed for continuous cement mixing and grouting. Its dual-tank structure supports continuous operation, and high-speed mixing ensures slurry uniformity, making it suitable for projects requiring high quality, such as tunnel sealing and foundation reinforcement.

A Big Capacity Grout Mixing Plant (typically defined as plants with an hourly output exceeding 50m³ or single-batch capacities above 2000L) is designed for large-scale infrastructure projects, mining operations, or industrial applications requiring high-volume, continuous grout production.
