Abstract

This invention discloses a pelletizing device for producing low-dust EVA foaming masterbatch, belonging to the field of EVA foaming masterbatch pelletizing technology. It includes an extruder and a water-cooling mechanism connected to the outer surface of the extruder. A dryer is connected to the outer surface of the water-cooling mechanism, and a pelletizer is connected to the outer surface of the dryer. A second water-cooling mechanism is connected to the outer surface of the pelletizer, and a discharge box is connected to the outer surface of the second water-cooling mechanism. The device is characterized by including an inlet fan installed on the upper surface of the dryer. This low-dust EVA foaming masterbatch pelletizing device uses an extruder and a water-cooling mechanism to extrude EVA material. The dryer and pelletizer work together to remove moisture and cut the EVA material, improving cutting stability and reducing dust generation. The exhaust from the dryer and the outlet from the pelletizer work together to form a gas flow circulation, removing dust generated by the pelletizer.
