High Efficiency Single Screw Extruder The Main Purpose
- Jun 01, 2017 -

High-speed single-screw extruder main purpose pipe extrusion: for PP-R pipe, PE gas pipe, PEX cross-linked pipe, aluminum-plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon core tube and various co- The Plate and sheet extrusion: for PVC, PET, PS, PP, PC and other profiles and sheet extrusion. Other kinds of plastic extrusion such as silk, stick and so on. Profile extrusion: adjust the extruder speed and change the structure of the extrusion screw can be applied to the production of PVC, polyolefin and other plastic profiles. Modified granulation: suitable for a variety of plastic blending, modification, enhanced granulation.

SJ series single screw extruder design concept: ◎ high quality on the basis of high-speed, high-yield extrusion. ◎ low temperature plastic design concept, to ensure the extrusion of high-quality products. ◎ two-stage overall design, strengthen the plasticization function, to ensure the adjustment of high-performance extrusion. ◎ special barrier, BM integrated mixing design, to ensure that the material mixing effect. ◎ high torque output, extra large thrust bearings. ◎ gear, shaft for high-strength alloy steel, carburizing, grinding teeth treatment. ◎ high hardness, high finish, ultra low noise. ◎ material for 38CrMoAL / A nitriding, wear. ◎ strict temperature control accuracy, fan cooling. ◎ unique inlet design, with a perfect water jacket cold device. ◎ with groove surface feeding the bottom of the barrel, with enhanced feed function for high-speed high-yield extrusion provides a guarantee. Single screw extruder parameters Single screw extruder is a plastic extrusion line in a model, its technical parameters and models are as follows: 1, single screw extruder technical parameters: 1) extruder production capacity Q: The amount of plastic extruded per hour 2) than the flow rate: one per revolution per week extruder production capacity 3) nominal specific power: how much kg per hour processing of plastic power required 4) screw length to diameter ratio L / D: screw work Part length and screw diameter ratio 5) screw diameter Db: refers to the large diameter, series of standard 20,30,45,65,90,120,150,165,200,250,300 6) drive screw motor power P: KW 7) Screw speed: the speed of the motor through the reducer after the speed: n min-n max rpm 2, model Txtsj-150 \ 33 said screw diameter of 150mm, aspect ratio of 33: 1 single screw extruder.

Product advantages: to achieve the material melt at a lower temperature extrusion. Through the isolation gap to determine the role of shear, so that the material up

To a good homogenization. The melt-plasticizing process is controlled, that is, only particles smaller than the isolation gap can enter the melt channel.
