Core Technical Advantages

• 01 Inherent safety: Zero-electrical-spark hydraulic drive and explosion-proof hydraulic power unit with pneumatic control remove ignition sources associated with electric drives and static.
• 02 Mixing concept: Hybrid twin-shaft system pairing hollow high-speed paddles with solid low-speed paddles to combine intense micro-shear and robust macro transport.
• 03 Dead-zone-free processing: Low-speed solid paddles (0–50 rpm) provide bulk turnover; high-speed hollow paddles (0–100 rpm) provide dispersion; 4–5 rpm orbital revolution ensures uniformity without dead zones.
• 04 Industry 4.0: Industrial PLC provides real-time control of temperature, pressure, torque, speed and viscosity with comprehensive data logging and traceability for R&D and production optimization.

Application Scenarios

• Aerospace propellant manufacturing: Uniform mixing of high-viscosity, high-hazard solid rocket propellants.
• Specialty chemicals & defense materials: Safe processing of electrostatically charged, flammable or explosive powders with viscous liquids.
