CT series is single screw extruder for recycle PET flakes. PET flakes granulation line design as combination of single screw extruder and high efficient vacuum system streamlines the whole process, yet keeps the final pellets in good quality.

General Features:

The PET characteristic viscosity can be controlled very well without complicated precrystallization dryer system.

PURUI research and design new single screw with compactor especial for processing PET flakes.

double cutter and special insulation layer.

Adopt underwatering cutting system.

The IV drops a little during the whole production process. And the IV can be improved by adding some suitable additives.

Tech Features & Advantages

High efficient vacuum keeps the IV drop minor

Optimized screw design avoids yellowing

Streamline the process

Pre-drying-free technology saves energy up to 35%

Minimize the investment

Machine Technical Parameter

Double Layer Disc for excellent degassing

Double disc and mixing dryer, mixing and drying bottle flakes

Instruction: The strong friction and heat generated by the double blade plates cause the material to dry and shrink; the feeding amount is automatically controlled, and there are two sets of temperature monitoring systems.

Blade material: D2 Bi-metal

Steel thickness:8mm

Roots Vacuum Pump for compactor degassing

Fast start-up, low power consumption, low operation and maintenance costs, high pumping speed, high efficiency, insensitive to the small amount of water vapor and dust contained in the pumped gas, and a larger pumping rate in the pressure range of 100 to 1 Pa. Can quickly remove the suddenly released gas.

Under water cutting system

Since the plastic is scraped off by the blade in the melt state and solidified after being cooled by circulating water, the pellets under the melt will not form any dust, and the pellets are of regular shape and uniform size, and the packaging and transportation are more convenient.

The molten plastic is directly cut into pellets after flowing out of the die hole, and is taken away by the cooling water in time. As long as the temperature and flow rate of the circulating water are controlled, the crystallinity of the product can be controlled. The quality of the pellets is very stable, and the transparency and gloss are very stable. Degree is higher.

Since the pelletizing is carried out under water, the oxidation of the product in the air can be avoided.
