Planetary extruder is usually organized by "extrusionsystem" ,rotationsystem , charging system and temperature controlsystem. The extrusionsystem hasa unique structure, the characteristicsof planetary extruder isbecause of theextrusion system.
The most important part of planetary extruder is planet screwbarrel,itsmain function is to make raw material molten , plasticizingand mixing. Theitemis organized by a central screw, numbers of planetscrews and barrelwithintramural hobbing, these three components is akey of planetary extruder.Allthe components (The center screw" planetaryscrew and barrel )are processedbyhigh quality alloy steel materialwhich is high tensile ,strength andabrasionresistance. The number ofplanet screws is in proportion to the diameterofplanetary section, generally for 6 to 18.
Because of its high production, the planetary extruder is the best choicetoprocess PVC and other materials, such as the the EVA sheet.Singlescrewextruder's production of same type product is 800 kg perhour,twin-screwextruder production is 1200 kg per hour, and theplanetary extruderproductionis 2000 kg per hour.
