bentonite slurry grout plant

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.

A grout plant for tunnel projects is a specialized system used in underground construction, especially in Tunnel Boring Machine (TBM) or shielded TBM operations. Its primary function is to prepare and supply grout mixtures used to fill the annular space between the tunnel lining (segments) and the surrounding ground.

High pressure grout mixer plant is a kind of equipment specially designed for efficient preparation and delivery of high-quality grouting materials, suitable for application scenarios that require high-pressure injection. This type of equipment usually integrates an efficient mixing system and a high-pressure pumping system to ensure that the grouting material is evenly mixed and stably and accurately injected into the target area under high pressure conditions.

A bentonite slurry grout plant is designed to produce, store, and supply bentonite slurry for use in grouting applications, particularly in civil engineering, construction, and foundation projects. Bentonite slurry is a mixture of water and bentonite clay, known for its high viscosity, thixotropic properties, and ability to form a stable, impermeable barrier when hydrated.
