  • Q
    What is solid propellant?
    Solid propellant is a fuel used in rocket and missile propulsion systems thatt has the ability to directly convert chemical energy into kinetic energy. It is a pre-mixes solid chemical substance that, once ignited, can continue to burn and produce a large amount of high-temperature and high-pressure gas.
Characteristics of Solid Propellant
  • 1. Good Storage Stability

  • Solid Propellant is stable at room temperature and easy to store and transport.

  • 2. Simple Propulsion System Design

  • No complex fuel and oxidizer delivery system is required, the propulsion device has a simple structure and high reliability.

  • 3. Easy to Start and Operate

  • Once the solid propellant is ignited, it can be burn continuously, the propulsion device starts quickly and is easy to operate.

  • 4. High Energy Density

  • Solid propellants have high energy density and can generate a large amount of thrust per unit mass of fuel.


Application of Solid Propellant

Solid propellant is widely used in the military and aerospace fields, providing powerful power suport for various rockets and missiles. By optimizing the composition and structure of the solid propellant, its performance and safety can be further improved to meet the needs of different missions.

Why is vertical kneader suitable for producing solid propellant?
  • 1. Efficient Mixing and Kneading Capacities
    • Uniform Mixing: Vertical kneader can evenly mix the various components of solid propellants, including oxidizers, fuel, binders and additives, ensuring the consistency and uniformity of the final product.
    • High Shear Force: Vertical kneader provides high shear force, which helps to thoroughly disperse and evenly distribute fine particles, especially suitable for mixing high-density materials such as metal powders.
  • 2. Handling High-viscosity and High-density Materials
    • Strong Adaptability: Vertical kneader is particularly suitable for handling high viscosity and high density materials. Solid propellant usually appears as high viscosity pastes during the mixing process, and vertical kneader can effectively handle such materials.
    • Powerful Kneading Action: Kneading blade design of vertical kneader can exert sufficient kneading action on high viscosity materials to ensure that the materials are mixed evenly without "dead corners".
  • 3. Temperature and Pressure Control
    • Temperature Control System: Vertical kneader is equipped with an advanced temperature control system that can accurately control the temperature during the mixing process, ensuring that the chemical reaction is carried out under optimal conditions and preventing local overheating or uneven temperature.
    • Pressure Control: Some vertical kneaders can operate under controlled pressure to further optimize mixing and reaction conditions.
  • 4. Sealing and Safety
    • Good Sealing: Vertical kneaders usually have good sealing performance to prevent the leakage of flammable or toxic substances during the mixing process, improving production safety.
    • Safety Design: High safety is taken into account in the design of vertical kneader, including explosion-proof measures and automated control systems, which can monitor and control key parameters in real time during the production process to prevent accidents.
  • 5. Easy to Clean and Maintain
    • Design for Easy Cleaning: The design of vertical kneader makes it easy to clean and maintain, especially when handling different batches of propellants. Easy cleaning can reduce the risk of contamination and cross-mixing.
    • Durability: Vertical  kneader is made of wear-resistant and corrosion-resistant materials, which can withstand high-intensity working conditions for a long time and extend its service life.
  • 6. Automation and Control System
    • High Degree of Automation: Modern vertical kneader is usually equipped with automated control systems that can accurately control mixing time, temperature, pressure and stirring speed to improve production efficiency and consistency.
    • Data Monitoring: Real-time data monitoring and recording functions can help operators adjust parameters in time to ensure product quality.
