Bentonite clay grouting mixing plant
Bentonite clay grouting mixing plants use high shear forces to break up bentonite particles and ensure they are thoroughly mixed with cement and water to form a uniform slurry. Some equipment, such as AMIX Systems’ colloid mixers, utilize high-shear mixing technology to fully hydrate the bentonite in under two minutes, improving slurry quality.
A bentonite clay grouting mixing plant is an integrated device that combines slurry production and storage functions. It is designed for rapid mixing of bentonite, cement, water and other media. It is widely used in waterproofing and leak plugging, tunnel lining, foundation reinforcement and rock filling in road, railway, hydropower, construction and mining projects.




Typical applications of bentonite clay grouting mixing plant:
Tunnel and Underground Engineering
Bentonite slurry is used for tunnel lining grouting, forming a waterproof layer and preventing groundwater infiltration. Bentonite can be quickly mixed with cement and pumped behind the lining using high-pressure pumps to provide a seal and reinforcement.
Foundation Reinforcement and Rock Filling
Bentonite slurry is injected into foundation cracks or rock voids to improve bearing capacity and stability. High-pressure grouting is used to fill mined-out areas and prevent surface collapse.
Waterproofing and Crack Repair
Bentonite slurry is used to repair cracks in buildings, forming a flexible waterproof layer. Ultrafine cement and bentonite can be mixed and injected at low pressure to fill concrete cracks and prevent water infiltration.
