SJSZ Conical Twin Screw Extruder for PP, PE, PS, PVC, PET,

Zhangjiagang City B&E Machinery Co., Ltd

 Characteristic & Application

 

This series extruder with appropriate diemould and auxiliary machine can directly convert thermoplastic especial PVC powder into pipe, plate sheet, film and profile, and also provide function of modifying and pelleting.

 

The extruders are derived by D.C motor with a thruster to steeples regulate. It is also equipped with the over-load protection and stoppage alarming system. The screw’s core and the outside of barrel is cooled by circulation of oil, it includes vacuum venting and forced feeding.

Characteristics:

 

1. This machine can produce pipes, panels and profiles directly from PVC powder.

2. There are two kinds of electric controlling systems for this extruder, common instrument control system and computer

     control system.

3. For chief driving methods, direct current timing and converted frequency control timing are available.

4. It exquisitely designed screw and barrel have perfect plasticization effect.

5.The electric control system adopts the most advanced technology and there is an alarming system for every subsection failure.

6. It is convenient to examine and repair.

7. The high-performance distribution system for torque deceleration is wearable and easy to maintain.
