1)Main motor with a power of 22KW (AC motor), which is produced by Siemens motor manufacture. The Denmark Danfoss frequency control is used for speed adjusting.2)One set of main feeder,the power is 0.75kw, reduction ratio:17:1. The feeder with a horizontal agitator, feed trandsmission case with lubricant grease, hopper material is stainless steel
3)Hight speed hight torque gearbox, reduction ratio:2.5:1, 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:Φ35.6mm, L/D =44:1, 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: 11barrels in all, barrel length:150mm per section, which is made of #45 steel and lined with alloy bush, water-cooling for barrels. The first barrel is for feeding; the fifth barrel is open side barrel, the side feeder have blind block;the upper open is the mouth of liquid,the second ,fifth and seventh is liquid charging barrel ,and with liquid charging pin valve, the ten barrel is for vacuum degasification, and the eleventh one is for extrusion.,and others are for close barrels.
6)Heat system :11 sections in all which contain screen changer die .Cast copper for first and second section, cast copper heat for die,and cast aluminum for others, the heating power is high, the outside of heater is made of asbestus to keep the temperature, which effect is good, heater insulating resistance against ground is not less than 10 MΩ,heating power is ~20kw
