Planetary extruder is usually organized by "extrusion system" , rotation system , charging system and temperature control system. The extrusion system has a unique structure, the characteristics of planetary extruder is because of the extrusion system.

The most important part of planetary extruder is planet screw barrel, its main function is to make raw material molten , plasticizing and mixing. The item is organized by a central screw, numbers of planet screws and barrel with intramural hobbing, these three components is a key of planetary extruder. All the components (The center screw" planetary screw and barrel )are processed by high quality alloy steel material which is high tensile ,strength and abrasion resistance. The number of planet screws is in proportion to the diameter of planetary section, generally for 6 to 18.

Because of its high production, the planetary extruder is the best choice to process PVC and other materials, such as the the EVA sheet. Single screw extruder's production of same type product is 800 kg per hour, twin-screw extruder production is 1200 kg per hour, and the planetary extruder production is 2000 kg per hour.
