Paddle mixer VK-2000

verticalbatchpowder

Overview
The explosion-proof vertical kneader is an ultra-safe intelligent mixing system engineered by JCT Machinery for aerospace propellants and hazardous polymer composites. Fully hydraulic with intrinsic explosion protection and Industry 4.0 data logging. Available capacities: 10 L–5000 L.

Key Features

• 01 Inherent safety: Zero-electrical-spark hydraulic drive architecture — hydraulic motor direct drive eliminates electrical-spark and static risks in the mixing zone.
• 02 Ultimate mixing: Synergistic kneading using dissimilar twin shafts (low-speed solid paddles and high-speed hollow paddles) to combine macro-level turnover with micro-level shear.
• 03 Industry 4.0: PLC-based continuous monitoring and data mining enabling real-time automatic control of temperature, pressure, torque, speed and viscosity; full data logging and batch traceability.

Application Scenarios

• Aerospace propellant manufacturing: Engineered for high-uniformity mixing of solid rocket propellants with high viscosity and hazardous constituents.
• Specialty chemicals & defense materials: Safe processing of electrostatically active, flammable or explosive powders blended with viscous liquids.

Equipment Parameters
Model | Full Volume (L) | Useful Volume (L) | Min Volume (L) | Power (kW) | Pericentric Blade Speed (rpm) | Telecentric Blade Speed (rpm) | Revolution Speed (rpm) | Clearance (mm) | Vacuum Abs Pressure (kPa)
VK-2000 | 2000 | 1200 | 200 | 55 | 0~50 | 0~100 | 4~5 | 7±1 | <1.5

Additional Notes
The VK-2000 can be configured across the 10 L–5000 L range. Design focus: intrinsic no-spark hydraulic drive, high-torque hydraulic direct drive, hybrid paddle geometry for dead-zone-free kneading, explosion-proof hydraulic power unit and fully pneumatic control logic for defense-grade safety.
