Plastic Granulating Production Line (Energy-saving and Environmentally-friendly Model) is a machine that converts waste plastics such as polyethylene and polypropylene into plastic granules through extrusion, cooling, and granulating processes. The produced granules have wide applications and are for sale. It is an ideal investment project for farmers and laid-off workers. The water ring cutting granulator equipment is paired with a crushing and cleaning machine and granulator production line, featuring simple processes, advanced technology, automatic temperature control, electric heating, low electricity consumption, no pollution, and high automation.
