LGP400/1000/90DPL-E Automatic bentonite mixing plant and pump is an all-in-one bentonite slurry preparation system built on a single integrated skid frame, combining a high-speed vortex mixer, a continuous agitator tank, and a grouting booster pump into one compact unit. Its streamlined footprint makes it highly portable and easy to relocate between job sites with minimal setup time.
 
Purpose-built for bentonite slurry production, this plant is extensively deployed across both above-ground and underground civil engineering projects — including highways, railways, hydropower stations, building construction, and mining operations.
Powered by advanced high-speed vortex mixing technology, the system rapidly blends water and bentonite powder into a fully homogeneous, colloidal-grade slurry in seconds — ensuring consistent quality with every batch and eliminating the risk of clumping or uneven concentration. The mixer is designed with an auxiliary impeller, and the agitator is designed with a small, high-speed impeller.
 

The LGP400/1000/90DPL-E Automatic bentonite mixing plant and pump are primarily designed for bentonite slurry preparation and grouting. Specific application scenarios are as follows:
1. Pipe Jacking / Microtunneling: Lubricating slurry to reduce pipe-soil friction
2. TBM Tunneling (EPB/Slurry TBM): Face stabilization, cuttings transport, pressure balancing
3. Horizontal Directional Drilling (HDD): Drilling fluid management
4. Diaphragm Wall Construction: Trench stability slurry
5. Drilling Piles (Bored Piles): Wall stabilization during drilling
6. Grouting & Sealing: Injection into cracks, joints, and voids for waterproofing
7. Foundation Reinforcement: Soil consolidation, compaction grouting
8. Anchoring Systems: Rock bolts, soil nails, micro-piles

1. Compact and reliable structure.    
All-in-one skid-mounted design combining mixer, storage tank, and pump on a single robust base frame — space-saving yet built to handle demanding jobsite conditions.
2. Easy to operate and convenient to maintain.    
Fully PLC-controlled with an intuitive touch-panel interface — operators can manage dosing, mixing speed, and pump output with minimal training, while quick-access components simplify routine servicing.
3. Fewer spare parts are required, effectively reducing maintenance costs.    
Minimized wear components and simplified hydraulic layout mean fewer spare parts on hand, significantly cutting down both inventory costs and unplanned downtime on site.
4. The high-speed vortex mixer delivers fast and uniform mixing.
Equipped with a high-shear turbo vortex mixer that produces a fully colloidal, homogeneous slurry in seconds — eliminating clumping and ensuring consistent bentonite concentration throughout.
5. Wide range of applications.    
Versatile across multiple industries — from pipe jacking, TBM tunneling, and HDD drilling to diaphragm walls, bored piles, and ground grouting — one plant handles them all.
6. Specially designed for bentonite mixing.    
Purpose-engineered for bentonite slurry preparation with precision load-cell dosing and continuous agitation, reducing bentonite consumption by up to 50% compared to conventional manual mixing.
