Wet Granulation Plastic Pelletizing Machine , Twin / Single Screw Extruder

Wet granulation PVC pelletizing machine twin screw single screw granulator

The main working way of the PVC granulator is pelletizing with wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after the body is humidified in the cylinder. Under certain liquid phase conditions, the rotating movement of the barrel is used to make the extrusion pressure of the material into the ball.

The main advantage is to use steam to heat moisture, improve the temperature of the granulation material itself, reduce the granulation water, reduce the load of the dryer, and improve the working efficiency. The granulating rate of the rotary drum granulator can reach 70%, and the equipment is simple in operation, flexible in operation and convenient in maintenance. The equipment is lined with ultra high molecular weight polyethylene (UHMW-PE), which eliminates the sticky wall phenomenon of the material, reduces the labor strength of the workers, and greatly prolongs the service life of the equipment.
