Problems solved by technology

The existing equipment for producing foamed resin microspheres for physical sensitization of emulsion explosives is mainly composed of a feeding device, a heating device, a single screw feeding rod and a feed pump. Foaming resin microspheres, but the equipment has the defects of complex structure and extremely low production efficiency, and the foamed resin microspheres produced for physical sensitization of emulsion explosives have a particularly small density, are very light, and can float in the air. , once the product leaks, it will make the production environment quite bad and seriously affect the health of the production personnel. Therefore, this equipment is not promoted.
[0003] In addition, the temperature of the foamed resin microspheres for physical sensitization of emulsified explosives processed by the existing equipment is very high. If the product is not cooled in time, the product will stick at high temperature and affect the quality of the product.
