Featuring a cantilevered structure with a "zero-bottom-shaft-seal" design and high-efficiency planetary kneading, propellant vertical kneader eliminates the risk of friction-induced detonation at the source; it is a core piece of equipment for achieving intrinsic safety and ultra-uniform mixing of high-viscosity, flammable, and explosive compositions.

Advantages of Propellant Vertical Kneader
- The kneading blades perform a planetary rotation within the vessel, eliminating dead zones and preventing material from sticking to the walls.
- Safety hazards and foreign object contamination caused by material corrosion of bearings and seals are avoided.
- Long-term, stable vacuum performance is maintained within the vessel, reaching levels as low as -0.1 MPa.
- The vessel jacket works in conjunction with a temperature control unit to effectively regulate material temperature.
- It can be used interchangeably with multiple vessels, facilitating easy discharging and cleaning.
To meet the high standards for safety, stability, and quality in the pyrotechnic composition manufacturing industry, JCT solid propellant vertical kneader incorporates multiple advanced design concepts and comprehensive safety measures:
1. Explosion-proof Rating
Ex d IIB T4 or the highest grade Ex d IIC T4; full-system explosion protection.
2. Sealing Structure
Magnetic seal or highly airtight multi-component seal; exceptional airtightness.
3. Control Method
Remote, isolated PLC centralized control; fully automated digital operation from an explosion-proof control room.
4. Discharge Method
Hydraulic lift-and-lower bottom discharge, or lateral transfer of the entire vessel to the casting station.
5. Material Requirements
Product-contact surfaces made of SS316 with mirror polish (high-precision electrochemical polishing).
We possess extensive experience in the R&D and manufacturing of high-viscosity, explosion-proof vertical kneader and can provide tailored solutions based on your specific process requirements (capacity, vacuum level, and explosion-proof rating):
