Product Manual：1.Suitable for PET bottle flakes
2.The screw is made of high tool steel W6Mo5Cr4V2
3.double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficie
Parallel & tri-axial structure and dual rack drive system. Gear and shaft made of fine quality material, SKF bearing oil-immersion lubricating system, low oil position & overpressure alarming system. High rotating speed high torque high yield.
Screw Kneading block built on modular principle allows various L/D ratio of screw easily be changed to suit different material. Screw component made of high speed & wear-resisting steel.
By means of the replaceable screw barrel sections, the processing sections is devided into individual zones. The barrels are heated electrically. In addition, the barrels are provided with longitudinal bores for cooling with water. Uniform temperature distribution, namely on the circumference of the eight-shaped barrel bore, is achieved by a reverse force-flow temperature control circuit. Connections of pipes for temperature control are in groove-tongue design to balance alternating thermal stress and avoid leakage.
The screw barrels are made of nitrided steel. In order to increase the service life of the screw barrels, these are provided with wear resistant inserts.
