Before most materials can be made into final products, they must be compounded and then granulated to become salable raw materials. There are many different designs of waste recycled plastic extrusion granulator, but all plastic granulator machine can be divided into two main categories: cold pelletizing systems and die face hot pelletizing systems. The main difference between the two lies in the timing of the pelletizing process. Cold pelletizing systems cut pellets from the solidified polymer at the end of the process; while hot die-face pelletizing systems pelletize the polymer as it emerges from the die in a molten state and the pellets are processed downstream cool down.

Cold pelletizing system:

The pelletizing system includes a die, a cooling zone (air-cooled or water-cooled), a drying zone (if water-cooled) and a pelletizing chamber. There are two types of cold pelletizing systems, namely flake granulator and strip granulator.

Die surface eager cutting system:

There are three basic ways of die face cutting system, namely air flow granulator, water ring granulator and underwater granulator. While such systems can be of various designs, a typical system includes a die, cutting chamber, motorized rotary blades, cooling medium, and method of drying the pellets.

According to the special requirements of the size, shape, quantity and model of plastic leftovers, different plastic granulator can be designed and manufactured. Depending on the application, such as films, profiles, pipes, and sheets, extrusion processing machines can use side-mounted granulators or central plastic extrusion granulator.
