C, Specification of the Machine
1, GTE-65B twin screw host machine(L/D=40)
| Specification | Description |
| Main motor | 90KW (AC), which is produced by Siemens motor manufacture. The Japan YASKAWA frequency converter is used for speed adjusting. |
| gearbox | High speed and high torque gearbox, and reduction ratio is 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. The material of gearbox is 40CrNiMoAlA and the machining precision is 6 grade. |
| Screw | Screw diameter: Φ62.4mm, L/D = 40:1 and the screw is blocking type. The screw core shaft is made of 40CrNiMoA, and the screw thread components connect with easy disassembly and assembly. The screw components are made of high quality high-speed tool steel, W6Mo5Cr4V2, that receives heat treatment with vacuum hardening at high temperature. Whole hardness: HRC58~60. |
| Barrel | Barrel length: L = 240mm/section. 10 sections barrel body. The barrel body is made of #45 steel with alloy cover. Barrel cooling way: Water cooling. The first barrel is used for feeding materials; the 5.7.9th barrel is for atmosphere venting, the 10th barrel is for extrusion. The other barrels are of closed mouth type. |
| Heating system | 9 sections for heating (including screen changer and die). The cast iron heaters are used for heating. The heating efficiency is high and temperature maintaining effect is good as the the asbestus used outside the heater. The insulating resistance against ground of heater is more than 10MΩ and total heating power is about 40KW. |
