Extruder:
Barrels and screws are both designed with building blocking principle. According to the material performance and tec

1)Main motor with a power of 200KW (AC motor), brand name is Siemens. 

The Japan FUJI frequency converter is adopted for the speed regulation system.

2)One set of the main feeder, the power is 2.2kw, reduction ratio is 17. The feeder with a horizontal agitator, feed transmission case with lubricant grease, hopper material is stainless steel.

3)High speed high torque gearbox, reduction ratio is 3, the compact host machine features integrated speed reduction and torque transfer with a design of parallel three axles. SKF bearings are used in the reducer, torque transfer device and as the radial bearing in the output shaft, which material is 40CrNiMoAlA, machining precision is six grade.

4)Screw stem diameter is Φ82mm, L/D =40, Screw stem with modular structure. The screw core shaft is made of 40CrNiMoA, and the screw thread components connect with the core shaft in an involute curve, which features high intensity, large load, and easy disassembly and assembly. The screw components are made of high quality high-speed tool steel, W6Mo5Cr4V2, which receives heat treatment with vacuum hardening at high temperature. The whole hardness is HRC58~60.

5)Charging barrels 10barrels in all, barrel length:320mm per section, which is made of #45 steel and lined with alloy bush, water-cooling for barrels. The first barrel is for feeding; the sixth barrel and eighth barrel are for vacuum degasification, and the tenth one is for extrusion, and others are for close barrels.

6)Heat system 10 sections in all which contain screen changer die . The cast copper heater is used for the first, second section and die, cast aluminum heater is used for the other sections. The heating power is high, the outside of heater is made from asbestos to keep the temperature, which effect is good, heater insulating resistance against ground is not less than 10 MΩ,the total heating power is ~85kw

7) Base adopts the high quality welding, which have speciosity, high strength, toughness and reliable ,the material of barrel cover is stainless steel.
