Propellant kneader is a high-safety mixing equipment designed for high-viscosity, flammable and explosive propellant materials or those that require precise mixing. It is widely used in aerospace, military, chemical and other fields to produce high-demand products such as solid rocket propellants and explosive binders.



Main Features of Propellant Kneader
  • 1. Structural design

  • Double-blade structure, mostly using Z-shaped blades, with strong shear force, mixing evenly and thoroughly.

  • 2. Material adaptability

  • Can handle high viscosity (>1,000,000cps), high solid content, high filler system materials.

  • 3. Jacket heating/cooling

  • Can pass heat transfer oil or water to accurately control the reaction temperature and prevent local overheating from causing safety hazards.

  • 4. Vacuum system

  • Can remove bubbles and volatiles in the material to improve product density and stability.

  • 5. Explosion-proof electrical system

  • Use explosion-proof motors, electronic control compoents and operation panels, suitable for flammable and explosive working environments.

  • 6. Discharging method

  • Usually bottom discharging to ensure that high viscosity materials can also be discharged smoothly.
