The cylinder of the PET bottle recycling granulating system is made of 45# forged steel inlaid wear-resistant alloy sleeves (or the overall 38CrMoAlA nitrided steel, nitrided).
The cylinder of the PET bottle recycling granulating system is made of 45# forged steel inlaid wear-resistant alloy sleeves (or the overall 38CrMoAlA nitrided steel, nitrided), the radial bearing of the output shaft of the reducer is made of German INA bearings, and the main shaft is made of special alloys. Material manufacturing, carburizing treatment, threaded elements are made of alloy steel, vacuum quenching or nitriding heat treatment, the heater is heated by cast aluminum or cast copper electric heater, Japan RKC dual-channel PID digital intelligent temperature control instrument, INVT constant torque AC variable frequency speed governor, vacuum exhaust, reduction box with oil cooling system, cylinder with soft water cooling system, stainless steel water tank, blow dryer, pelletizer, electrical control cabinet, etc.
The screw of the PET bottle granulator is generally divided into 5 sections: conveying section, melting section, mixing section, exhaust section and homogenization section.
1. Conveying section, conveying materials to prevent overflow.
2. Melting section, this section makes the material fully melted and homogenized through heat transfer and frictional shearing.
3. The mixing section further refines and uniformizes the size of the material components, forms an ideal structure, and has the function of distributing and dispersing mixing.
4. The exhaust section discharges impurities such as water vapor and low molecular weight substances.
5. Homogenization (metering) section, conveying and pressurizing, establishing a certain pressure, so that the material at the die mouth has a certain density, and at the same time further mixing, and finally achieve the purpose of smooth extrusion and granulation.

Extruder
A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content.
Noodle Cutter Strand Type Cutting System
The length of the sink is 4 meters, which can be adjusted up and down, and the stainless steel pipe is designed to change water.
The sink is made of 2mm thick stainless steel plate.
Vibration Drying System
Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
