High speed bentonite mixer

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.

The high-speed bentonite grouting mixer is a mixing device specifically designed for bentonite-based grouts (such as cement-bentonite grout). Its core features include:
High-efficiency mixing: High-speed vortex flow (typically driven by a special pump) achieves rapid slurry homogenization, reducing mixing time to less than one-third of traditional equipment.
Continuous operation: The integrated mixing tank and slurry storage tank supports simultaneous mixing and pumping, meeting the continuous construction requirements of underground projects and tunnel grouting.
Stable quality: Forced vortex circulation prevents slurry sedimentation, ensuring consistent slurry parameters such as density and viscosity.
The LMA750-1500E high speed bentonite mixer utilizes an integrated “mixing tank + slurry storage tank + high-pressure pump” design, achieving a mixing efficiency of up to 750L/batch and a slurry storage capacity of 1500L, making it suitable for large-scale projects.

High Speed Bentonite Mixer Typical Application Scenarios:
1. Underground Projects
Used for grouting to reinforce surrounding rock or to stop water from collapsing or seepage during subway tunnel and underground pipeline construction. Case Study: A subway project employed the LMA750-1500E equipment, completing over 200 m³ of grouting per day and increasing efficiency by 40%.
2. Foundation Treatment
In soft soil foundation reinforcement, high-pressure injection of bentonite slurry fills pores and improves bearing capacity.
Advantages: Slurry uniformity ensures precise control of foundation settlement and reduces subsequent maintenance costs.
3. Environmental Protection Projects
In landfill anti-seepage layer construction, bentonite slurry is used as a sealing material to prevent leachate leakage.
Features: High-speed mixing ensures full hydration of the bentonite, forming a dense colloidal barrier.
