Representative Materials Working Capability Schedule of SP 65-150

Twin/ Single-screw Two-stage Extruder (Reference Values)

Typical work :

    It has been abroad applied to various thermo sensibility material series and great capability dehydration and volatilization work, such as PVC, XLPE, Zero halogen cable, shield material, high concentrationcarbon black masterbatch, after treatment of rubber dehydrating. 

Characteristic :

♦  The first stage is SHJ twin screw extruder without die. Through the combination of barrel and screw, the extruder can exert its strong ability the thermo sensibility material like PVC melting, compounding, dispersing and decentralizing under the condition of no back pressure.

♦  The second stage is SJ single screw extruder. Because of the lower rotating speed, it can melti, compound lengthways and form strands steadily, avoiding over heating.

The Characteristics of The TSE-75 Series Twin Screw Extruder :

1.The gearbox:

·  New-style project of parallel three-axises driving makes the convey axis, convey chain, decelerate and the torque assignment get together, which keep it compact, and the key bearings are imported.

· The select material of drive components is dainty, including super intension alloy cementiteing steel, cementiting and quenching, gear grinding technics, strengthening of tooth face. So they can ensure high torque, high precision and low noise.

· Soakage and coerce lubrication integrate smoothly. When the hydraulic circuit is over pressed, it alarms.

2.The feeding system

· Metering feeders are equipped with single screw, twin screw, hollow screw, forced-feeding, side feeding, liquid-adding system,etc.

3.Screw                  

· The screw elements and then kneading blocks are designed accurately, by precise processed, agile combination, with interchangeability, which can fulfill efficient self-cleaning, transmission, compounding, pressure-forming.

· The screw material is made of high tool steel 38CrMoALA or W6Mo5Cr4V2 by special heat-treament.

4.The barrel       

· Eurostyle rectangle barrel, reflux refrigeration is optimized and disposed, which makes temperature difference in C areas smaller.

· According to the material and special techinics demands, the material of cylinder can use high quality nitrided steel, corrosion proof or antifriction with corresponding process.

5.The heater

· Innovated design of heater tightened style insures high efficiency of heat transfer and high longervity of heater.

6.Pelletizing

· Variou modes of pelletizing, such as water-cooling strand, air-cooling pelletizing, water-ring pelletizing, under water pelleting, etc.

Auxiliary Machinery :

1.Electric cabinet 

2.Twin screw metering feeder (or Loss-in weight feeder) 

3.TSE-65 Co-rotating twin screw extruder machine 

4.Water cooling strand pelletizng line (includes water tank, air knife, pelletizer) 

 * According to your requirements, we can add high speed mixer, side feeder, Loss in weight feeder, etc.
