Technical Field

[0002] The main components of aerosol fire extinguishing agent are strontium nitrate, potassium nitrate, resin and dicyandiamide. During production, they need to be screened, ground, wet mixed, granulated, dried and bagged for standby use. Granulation is done before drying, mainly to prevent the wet mixed material from agglomerating when drying, and to prevent the powder material from being lifted up when the spread material is dried. The existing granulator uses a swing granulator, which has low working efficiency and is difficult to meet production requirements under heavy workloads. At the same time, the swing granulator is prone to leakage when working, causing the leaked material to be dried in advance, making it easy for the drying gas to blow it up, resulting in an increase in waste.
