Master Batch Pelletizing Extruder

Master Batch Pelletizing Extruder

Suitable material: PA/PE/PP/PET/PBS/TPU/PVC/POM/ABS

Machine fearure:

1. High-efficient force-feeder ensures high capacity feeding, low energy consumption.

2. Twin screw extruder, equipped with specially designed screw & barrel, venting system, has a very good output capacity.

3.Pelletizing style: strand with extrusion mould, even cutting ensures good shape.

Details:

1) Screw diameter : 22~133mm.  L/D= 28~68

2)Main drive motor :AC 5.5~550kw,speed regulated by ABB transducer inported from switzerlad

3)Screw rotary speed:50~800rpm

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

5) Barrel is totally 6~17 pieces of barrels

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

7)Casting copper heaters or aluminum heaters for option.

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 7.5T/A3

The gearbox consists of:

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

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

• Bottom part of casing designed as oil Pump
