Planetary extruder is usually organizedby "extrusionsystem" ,rotationsystem , charging system and temperaturecontrolsystem. The extrusionsystem hasa unique structure, thecharacteristicsof planetary extruder isbecause of theextrusion system.
The most important part of planetary extruder is planetscrewbarrel,itsmain function is to make raw material molten ,plasticizingand mixing. Theitemis organized by a central screw, numbersof planetscrews and barrelwithintramural hobbing, these threecomponents is akey of planetary extruder.Allthe components (The centerscrew" planetaryscrew and barrel )are processedbyhigh quality alloysteel materialwhich is high tensile ,strength andabrasionresistance. Thenumber ofplanet screws is in proportion to the diameterofplanetarysection, 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'sproduction of same type product is 800 kg perhour,twin-screwextruderproduction is 1200 kg per hour, and theplanetary extruderproductionis2000 kg per hour.
