Ⅱ、Technical Data
1、Dehumidifying and Crystallizing Equipment
Other companies use a vertical system, and it is only for drying, and our system is for dehumidifying and crystallizing. Because the molecular chain of the PET bottle flakes is broken, and our system can link them and plays a physical viscous role which can greatly improve the tensile strength of the final products
Main technical parameters:
Capacity: 600 kg;
Quantity: 2pieces
Blender motor power: 4kw
Fan motor power: 2.2kw
Heating power: 18kw (can switch)
Automatic feeding machine 1 piece Motor power: 2.2kw
2、SJ-75/33 Single Screw Extruder
This machine is equipped with specialized reducer, and the gear and axial parts adopt high strength alloy steel and are treated by the carburization, quenching, gear grinding and other workmanship, and are matched with super thrust bearing which has the traits of high bearing capacity, stable transmission, and excellent efficiency etc. The material of screw and barrel is 38CrMoAlA, nitriding treatment, lower noise, corrosion resistance, wear resistance. Barrel is cooled by wind, heated by cast aluminum heating circle. The whole machine is equipped with automatic temperature controlling switchboard, digital display intelligent temperature controller.
