两阶排气型塑料挤出造粒机组由两台排气型塑料挤出造粒机串联成阶式的废塑料回收造粒设备，挤出机采用不同的螺杆设计，以适应不同种类的废塑料进行再生造粒。改机组可采用“丁字形”或“一字型”排列设计，以满足不同客户的需求。两台挤出机都设计有排气和快速更换滤网装置，可重复将物料加热后产生的气体排出，并经过两次过滤将物料的杂质过滤，使生产出来的颗粒更结实、光滑、纯净。改机组适用于ABS、聚苯乙烯（PS）、高压聚乙烯（HPPE）、低压聚乙烯（LPPE）、聚丙烯（PP）等废旧塑料的再生造粒，具有产量高、性能稳定、操作方便、经济效益后等优点；已被国内外广大客户所采纳。

Twice-Stage order vented style plastic extruding and granulating machine group with two venteed style plastic extrusion pelleting machine series into a cascade of waste plastics recycling granulation equipment, adopts different screw extruder design, so as to adapt to different kinds of waste plastics are recycled granules. The unit can be designed with "t-shaped" or "one-letter" arrangement to meet the needs of different customers. Two extrusion machine design have change exhaust and fast filter device, repeatable after heat the material produced by gas discharge, and after two filtering impurities filtration material, make the production of more solid, smooth, pure grain. Change unit is applicable to ABS, polystyrene (PS), high-pressure polyethylene (HPPE), low pressure polyethylene (LPPE), polypropylene (PP) and so on the regeneration of the waste plastic granulation, has high yield, stable performance, convenient operation and economic benefit after etc; Has been adopted by the majority of customers at home and abroad.
