High efficiency conical twin screw extruder SJSZ: 55/110
1) Extrusion system:
Screw diameter: Φ55mm,Φ110mm
Max. output: 120 kg/h
Screw material: using high quality alloy steel 38CrMoAIA, by nitriding treatment under high temperature, nitriding depth: 0.5-0.7mm, surface hardness: HV740-940.
Screw core temperature control: using internal recycle constant temperature device, for heat conduction then control the temperature of screw core.
Barrel material: high quality alloy steel 38CrMoAlA, by nitriding treatment under high temperature, nitriding depth: 0.6-0.7mm, surface hardness ≥ HV940.
Barrel temperature control system:
Heating zone: aluminium casting heating ring + stainless steel shell + cooling fan
Barrel cooling format: air cooling to control temperature in precision.
Heating zone qty: 10 zone, heating total power 16.5kw, temperature range 50~300°C
Barrel temperature control 4 zone, cooling fan power: 3x0.55kw/set, confluence core temperature control 1 zone, mold temperature control 5 zone.
Head connector: 38CrMoAIA, by hardening, tempering and surface nitriding treatment, runner surface is plated with hard chrome(Cr), using confluence format.
2) Transmission speed reduction system:
Using high torque reduction gear box
Water cooling temperature reduction device
Gear material of reduction gear box: 20CrMoTi, gear speed reduction apply with rigid tooth surface combining with oblique tooth surface; Gear nitriding & grinding treatment apply with Germany technology, which is with long life service, low noise, low energy consumption.
Horizontal reduction gear box: main motor is connected with reduction gear box through coupling device.
Distribution box: By hypercone gear, it changes from single shaft torque ouput to double shaft torque output.
3) Main motor system:
AC main motor:
Main motor power: 30 kw , 380V, 50Hz
Main motor speed regulation method: controlled by AC ABB frequency converter
