The main machine of plastic granulator is extruder, which is composed of extrusion system, transmission system and heating and cooling system. The screw barrel is an important extruder component.
The screw barrel of the granulation extruder manufactured by our company is made of high quality alloy steel 38CrMoAlA, which can be customized with double screw or single screw according to customer needs. It has large extrusion capacity, low energy consumption, good self-cleaning ability, and high aspect ratio of the screw can reduce the molecular viscosity of plastic polyester, and solve the problem of unreasonable input and output ratio.
1. Can be used for multi-functional, multi-purpose polymer material processing. It can make full use of the limited space to design the new involute spline structure mandrel to ensure the large bearing capacity and achieve high torque transmission.
2. With good self-cleaning function and good interchangeability. The specifications include conveying block, mixing block, kneading block, countercurrent block and tooth disk. Through the appropriate combination, can realize the material transportation, plasticizing, shear, dispersion, homogenization, exhaust, pressurization, etc., to realize the processing of polymer materials.
3. Extrusion material uniformity, material loss is small; Finished material made of high rate, good compactness, beautiful; High production efficiency.
4. With a set of mixing, delivery, feeding, extrusion, air-cooled hot grain, air-cooled cooling in one, to achieve automatic continuous operation, such a single screw granulation production efficiency is high.
Scope of application:
EVA sheet extruder, low smoke halogen free cable material granulator, soundproof felt sheet extruder, rubber sheet extruder, PET chemical fiber recovery granulator.
