GMA400-700AW Auto Mixing Station is a combination of screw feeder, mixer, agitator and auto weighing system based on PLC in one base frame. The quality of a grout mix depends solely on the effectiveness of the mixer used. The colloidal grout mixer is the fastest way for mixing. Widely used for water and cement, bentonite, and additives.
Model explanation of GMA400-700AW auto mixing station:

High-speed, high-shear colloidal grout mixer cause a vortex flow to ensures mix quickly and evenly. Compared with the traditional manual operation mode, this station has added the automatic operation mode, which greatly improves the working efficiency. Auto mixing station has compact size and it is easy to operate. It also takes up a small space.

GMA400-700AW auto weighing grout mixer, using the high shear high speed colloidal technologies, is the leading colloidal mixer in the industry, recommended by most grouting experts world-wide.

GMA400-700AW auto colloidal grout mixer is mainly used to be made the cement or bentonite slurry in the highway, railway, hydropower, construction, mining and other ground and underground construction applications.

GMA400-700AW auto mixing station is a fully automatic grouting machine.

1. 3 sets of stable weighing modules auto mixing plant.
2. Simple operation interface.
3. Auto high shear grout mixer is with PLC machine control.

4. Visualization interface.
5. Lower charging material height for the mixer.
6. High-speed colloidal auto grout mixer,.
7. Manual mode and fully automatic mode.
8. Precision of the ultrasonic liquid level meter.

9. Auto high speed grout mixer has remote control of the hose pump.

10. Multiple formulations can be set up.
11. Variable output with the variable-frequency drive of all motors.
12. Smoothly outflow slurry through the pneumatic pinch valve.

GMA400-700AW Auto mixing station specification (with electric motor drive):
1. Pneumatic pinch valve: the slurry flows more smoothly.
2. Ultrasound fluid level meter: height of agitator can be accurately measured.
3. Variable-frequency drive: all motor can be output with variable-frequency.
4. PLC+touch screen : manual mode and fully automatic mode.
5. Remote control : control hose pump: start, stop, accelerate, deceleration.
