Description

A kind of extruding pelletizing dryer for plastic granules

technical field

The utility model relates to a drying machine, in particular to a drying machine for extruding and cutting plastic granules, which belongs to the technical field of plastic granule processing equipment.

Background technique

The granulator is a molding machine that can manufacture materials into specific shapes. The molten polymer is extruded from a hot die and cut into pellets by a rotating knife that rotates on the die surface. The special feature of this sugar granulation system is its specially designed water spray granulation chamber. The water flows around the cause in a spiral until it flows out of the grain chamber. After the pellets are cut, they are thrown into the water flow for preliminary quenching. The pellet water slurry is discharged into the pellet slurry tank to be further cooled, and then sent to the centrifugal dryer to remove water. After the plastic pellets are extruded and pelletized, they need to be dried. However, the existing drying device uses external circulation when used, and heat The amount of loss is large, which increases the cost of drying. The fixed heating source in the drying room causes a temperature difference inside, which affects the drying efficiency, and the practicability is poor.
