Product Description
Double stage pelletizing line is especially good for the raw material which contain high moisture, high impurities.
The first stage extruder adopts exhaust type barrel screw, which can effectively de-gassing and eliminate the moisture and contamination;
And the second extruder usually adopts small L/D extruder, further plasticizing the material and filter contamination which can achieve stable extrusion.

>>Gearbox
Reduction transmission: High torque gearbox
Germany HENSCHEL / ZAMBELLO
Reduction ratio: I = 2.5:1.
Output power: P1 = 200 kW
Input speed N1 = 1500 rpm
>>Screw
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.
>>Barrel
By means of the replaceable screw barrel sections, theprocessing 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 eightshaped barrel bore, is achieved by a reverse forceflow temperature
control circuit. Connections of pipes for temperature control are
in groove-tongue design to balance alternating thermal stress and avoid leakage.
