Technical Field

[0001] The utility model belongs to the technical field of flame retardant production, in particular to a flame retardant fine grinding device. Background Art

[0002] Halogen-free flame retardant production process flow: 1. Reactor synthesis reaction; 2. Centrifugal dehydration; 3. Centrifugal wet material flash drying; 4. Weighing and packaging. The product particle size D98≤25um, D50 is about 4um. With the development of the flame retardant industry, higher requirements are put forward for the particle size of flame retardants, and the original product particle size cannot meet the requirements. (Generally, the finer the particle size, the better the compatibility of the flame retardant with the plastic base material, and the flame retardant is not easy to precipitate from the material, so the material maintains excellent flame retardant properties for a longer time) According to the needs, a fine crushing device for further crushing the finished product after flash evaporation is crucial to improving the quality of the flame retardant, and a flame retardant fine crushing device is needed.

[0003] At present, the Chinese patent with the announcement number CN218394028U discloses a halogen-free flame retardant fine grinding device, including a feeding mechanism, the discharging end of the feeding mechanism is assembled and connected with a grinding mechanism; the grinding mechanism is connected with a powder collecting mechanism, and the powder collecting mechanism is connected with an air induction mechanism; the grinding mechanism includes a barrel, the bottom of the barrel is fixedly connected with a grinding barrel, and the grinding barrel is assembled and connected with a grinding assembly; the grinding assembly includes an outer crushing knife ring rotatably connected in the grinding barrel, and the outer crushing knife ring is assembled and connected with a plurality of outer end crushing parts; the outer end crushing parts include a mounting knife frame, and the two ends of the mounting knife frame are respectively fixedly assembled and connected with an inner crushing knife and an outer crushing knife located on both sides of the outer crushing knife ring; the crushing assembly also includes a rotating motor for driving the outer end crushing parts to rotate. The above-mentioned device component design is adopted to realize the full refinement and crushing of solid material flame retardant in the production and processing of halogen-free flame retardant.

[0004] However, when the above device is in use, it relies on the outer crushing knife and the inner crushing knife for combined crushing. When the flame retardant is crushed by the knife, the knife needs to break it apart, which makes it difficult to turn the flame retardant into powder. When in use, the particles are large, resulting in a small coverage area. Utility Model Content
