The machine is composed of the main machine, air handling system, heating system, slurry handling system, control system, etc. When it works, the materials enter the silo of the boiling granulator. Set the procedures and parameters according to process requirements and the machine will start working. After filtered by the air handling system and heated by the heating system, the air enters the main machine. The slurries are sent by the slurry handling system into the spray gun and sprayed onto the materials in the cavity to carry out agglomeration of powders and form granules. After the operations are completed according to the set procedures and parameters, the material silo is pushed out and assembled onto the conical hopper of the lifting material transferring machine for lifting discharging, or is pumped to a high position by the vacuum feeder for granule sizing by the granule sizing machine, so as to effectively control dust pollution and cross contamination.
