Single screw machine and double screw machine: a is a screw, a screw is two root. All is to use a motor driven. Power for screw different and different. 50 cone double power of about 20 kw, 65 is about 37 kw. Production and anticipates the screw related, 50 cone double output is about 100-150 kg/H, 65 cone double is about 200-280 kg/H. Single screw production is only half.

plastic recycle machine according to the screw quantity can be divided into single screw, twin-screw and screw extruder. At present by the single screw extruder used the most extensively, suitable for general material extrusion processing. Pp Pe Recycling Machinehas the fricative heat less, material by shear is evener, screw the transport capacity bigger, extrusion quantity is stable, material in the machine in the cylinder to stay long, mixed evenly.

Single screw extrusion machine whether as plasticizing granulation machinery or molding processing machinery plays an important role, in recent years, single screw extruder had the very big development. At present the German production of large granulation with single screw extrusion machine, screw diameter of 700 mm, production for 36 t/h.

Single screw extruder main mark is the key parts – screw development. Since in recent years, people on the screw had a lot of theoretical and experimental research, has been nearly kinds of screw, common separation type, shear, barrier type, FenLiuXing and wave type, etc.

From single screw development to see, although in recent years the single screw extruder has more perfect, but with high polymer materials and plastic products continuously development, will emerge more characteristics of the new type of screw and special single screw extruder. On the whole, single screw extruder to high speed, high efficiency, specialty direction.

Plastic Recycling Equipment feeding characteristic is good, suitable for powder processing, and than single screw extruder have better mixing, exhaust, reaction and the clean function, the characteristic is processing thermal stability poor plastic and blending material more shows its superiority. In recent years abroad twin screw extruder has very big development, various forms of double screw extruder has series and commercialization, the production of more also manufacturers.
