Two Stage Extruder
ZL series, that’s two stage compounding extruder consisted of two parts. Mainly there are three types of two stage extruder combination:

1. Single screw main extruder machine-single screw submachine

2. Single screw main pelletizing machine-twin screw submachine

3. Twin screw main pelletizing machine-single screw submachine

The first two types are widely used for recycled plastic granulating.

And the third type for heat-sensitive material like PVC, POM, XLPE etc.

The twin screw extruder (SJSL-) at the first stage is to realize good shearing and compounding for material, and then the extrusion and pelletizing by YD single screw extruder (second stage). The new, scientific and advanced design and structure can avoid material decomposition caused by material overheating

Application of Twin-Single Screw Extruder

Carbon black master batch

PVC cable, PVC transparent bottle and blood transfusion tube materials

PE silicon hydride crosslink cable material, peroxide crosslink cable material

Wood- plastic blending material

Heat-sensitive polymeride.

Technical requirements:

Dynamic data: low voltage power supply standard(DIN/IEC38): 380ｖ

-5+10%, 50Hz-/+2% phase/N/PE 50Hz.

control voltage standard (transformed): 220V

AC( contactor, meter, electromagnetic valve ).

　　Temperature: 10-40℃.

Humidity: max.80%, no condensation.

Total wattage:～300 KW.

Water requirements: circulating water: The cooling recycling water in the barrel must

be soft water (distilled water).

Water sources: 1. Creating a pool (4-6㎥) outside the

workshop, using water pump to make

recycling water.

2. Using tap water directly, but it’s wasteful.
