Designed Around Your Mixing Challenges

Difficult-to-Mix High-Viscosity Materials

The low-speed frame agitator provides controlled bulk mixing while the scraper system helps improve material movement along the vessel walls and bottom.

Powder Dispersion

A separate high-speed dispersing system provides intensive shear for faster and more uniform dispersion.

Air Entrapment

The closed vessel is equipped with a vacuum system capable of reaching at least -0.09 MPa for vacuum processing and deaeration.

Difficult Discharge

This system is supplied with a dedicated hydraulic pressure discharge machine for controlled material discharge.

One Mixer - Multiple Processing Functions


Low-Speed Mixing

11 kW low-speed mixing motor

Frame-type agitator with PTFE wall and bottom scrapers for effective bulk mixing.

High-Speed Dispersion

15 kW high-speed disperser

Two toothed dispersing discs provide intensive dispersion with speeds up to 1,440 rpm.

Vacuum Processing

Vacuum down to -0.09 MPa

Designed for closed-vessel vacuum processing and air removal.

Hydraulic Discharge

Integrated pressure discharge

A dedicated hydraulic pressure unit helps discharge high-viscosity materials after mixing.

Concentric-Shaft Mixing and Dispersion

The concentric-shaft configuration allows mixing and high-speed dispersion to operate within the same processing vessel.
This design helps reduce material transfer between separate machines and provides a more compact solution for coating production.
For waterproof coating applications, the combination of low-speed bulk mixing and high-speed dispersion is particularly useful when the formulation contains powders, fillers, pigments or other difficult-to-disperse ingredients.

Built-In Safety and Protection

250L-Vacuum -Multi-Function- Mixer- for- Waterproof- Coatings (8)_副本

Emergency Stop

Pressing the emergency stop immediately stops the equipment.

Vacuum Interlock

The lifting system cannot raise the crossbeam until the vessel has returned to atmospheric pressure.

Vacuum Oil Backflow Protection

We stand for fair and affordable pricing policy and we have very beneficial regular discounts.

Motor & Drive Protection

The variable frequency drive provides protection against overload, overcurrent, overvoltage, leakage and phase loss.

Hydraulic Pressure Discharge for High-Viscosity Materials

After mixing, high-viscosity waterproof coatings can be difficult to remove from the mixing vessel by gravity alone.


For this reason, the system is supplied with an SXDYJ-250 hydraulic pressure discharge machine.


The pressure discharge unit uses a hydraulic cylinder and matching pressure plate to push the material out of the vessel, providing a more practical solution for viscous coating materials.
