Nanjing Yongjie started to make water strand twin screw extruder pelletizing machine since 2001,our twin screw extruders are widely used for enforcing modification, degradab le master batch, anti-flame master batch etc.
Water strand plastic pelletizing machine application
Reinforcement and modification: filling glass fiber or carbon fiber for :PP, PA, PBT, ABS, AS, POM, PPS, PET etc.
Compounding and blending: PC+ABS, PA,+ABS, PP+EPDM, PA+EPDM, PP+SBS, etc.
Filling modification: filling Caco3, Talc, Titanium, carbon black for PVC, PE, PP,EVA etc.
Cable material: LDE, HDPE, LLDPE, MDPE, drive pipe, insulation material, crosslinking material, cable coating material, thermal contraction material etc.
Special application material: PPR pipe compounds, PE crosslinking tube material, cigarettes filter tip material, acetable fiber material etc.
Thick color masterbatch: PE, ABS, PS, EVA, PET, PP+ pigment + additives, etc.
Flaming retarding material: PVC, PP, PA, ABS, EVA, PBT + fire retardant, etc
Special functional masterbatch: double protection masterbatch, antistatic masterbatch, anti-bacteria masterbatch, thermal insulation masterbatch, hypothermia material etc
The biodegradable masterbatch: PP, PE, PS+ starch + additives etc.
Quick details of the machine
Barrel&screw material:W6Mo5Cr4V2 high speed tool steel
Length of barrel:360*9 section=3240mm
Special screw array with wear shear of flake material, super power vacuum system to reduce IV loss maximumly.
Safety Clutch: Connected gearbox with motor to transmit power. High safety coupling with torque limit. When beyond setting torque, it will slip off to stop the machine running as a way to protect it.
Transmission gear: parallel tri-axial structure is combination of reduction and matrix. The gear is made of high quality alloy (20CrNi2Mo). It had been treated by cementation heat process, and the precision grade can reach 6th. It guarantees the tooth surface is high speed, low noise and high torque. Torque level up to 10.3 N.m/cm3
Drive bearing: Japanese NSK.
Lubrication: Gear bearings in the gear box will be of oil immersed. There is hydraulic lubrication in the gear engagement and gear bearings.
One temperature sensor: if the oil temperature more than 60 degrees Celsius, the extruder will stop automatically.
One pressure sensor: if the oil pressure less than 0.2 MPA, the extruder will stop automatically.
One pressure indicator meter for the operator to see the pressure easily.
Cooling: Lubricated cooling adopts shell and tube cooler and circulated water cooling method.
Fin-plate heat exchanger for good cooling
One vane pump to make less noise
Input/output rotary speed:1480/300 rpm
