 1) Screw diameter : 71mm.  L/D= 36:1/40:1/44:1/48:1

 2)Main drive motor :AC 132kw,speed regulated by ABB transducer inported from switzerlad

 3)Screw rotary speed:50~600rpm

 4)Screw shaft is made of high-strength alloy 40CrNiMoA.

 5)Lenght of each barrel is 290mm,totally 9 pieces of barrels

 6)The 1st barrel is the main feeding vent,the 5th is for degassing,8th is vacuum section,and the others are closed barrels.

 7)Casting copper heaters for 2.3th barrels.The others are equipped with casting aluminum heaters,All heating power:~50 kw

The extruder figure:

Feeding                        Degassing             Vacuum                                       










Four hinge style die section

8)Reducing and distributing gearbox:

   The gearbox reduces the motor speed to the speed of the screw shafts and distributes it to the 2 output shafts,

this gearbox output torque can reach 4.8T/A3


 The gearbox consists of:

l Involute gear teeth couplings between the output shaft and screw shafts

l Integrated thrust bearing assembly,radial bearings of the output axis are NSK products

l Bottom part of casing designed as oil sump
