TWIN-SCREW PVC PELLETIZING EXTRUDER

1. Screw and barrel are made of SACM-1 with heat and nitride treatment, each treatment is being carefully controlled. Given this, our screw and barrel are made with high resistance to acid and abrasion.
2. Barrel cooling: There are two types of cooling system for our customer, air cooling and oil cooling. Both cooling systems are able to stabilize the output quality and capacity during the production process
3. Gearbox: gears are made of steel alloy with heat treatment and are finished with surface precision grinding. By using oil injection cooling system, it reduces noise when operating under high RPM and enhances the life span of gears.
4. Degasification device can eliminate the moisture, gas and vapor generated by PVC resins during production process.
5. Control system is using SSR contactless switch, and PID system for temperature control.
6. Pelletizing Die Head: pelletizing dies are made of steel alloy with carbonizing treatment; it is fabricated with characteristic of high resistance to acid, abrasion and high temperature.
7. Vibration cooling unit: stainless steel machine frame and multi-hole cooling unit provide as pellet selection during the cooling process. It is also equipped with high power cooling vent.
