Product overview In the mixing and kneading processes for pyrotechnic compositions, solid propellants, and flammable or explosive polymer composites, the vertical kneader is recognized as a core piece of equipment offering the highest level of intrinsic safety and excellent mixing uniformity. Vertical kneader eliminates the critical safety hazard inherent in horizontal designs — where the shaft seal is located beneath the material and is prone to heat generation caused by friction and compression — making it widely used in specialized military and high-end civil explosives sectors.
Product details Pyrotechnic compositions are classified as high-risk chemicals characterized by sensitivity, flammability, and explosiveness; exposure to impact, friction, compression, flames, high temperatures, or static electricity can trigger combustion or explosions. Consequently, serious accidents are highly likely to occur during the production and storage of these materials.
