Imported Veblen Twin-Screw Extrusion Granulator

Twin-Screw Extrusion Granulator | Main Configuration Description of Twin-Screw Granulator Manufacturer

1. Screw Elements and Core Shaft
1) The screw and core shaft are connected using an involute spline. The modular barrel adopts wear-resistant bimetallic material with an α-101 inner lining and hard alloy sleeve. Screw elements are made of wear-resistant high-speed tool steel W6Mo5Cr4V2, while the screw core shaft is made of 40CrNiMoA material. The first barrel section is equipped with a main feed port, the third barrel section has a fiberglass port with a blind plug, the fifth section features a vacuum exhaust port, and the remaining barrel sections are closed.
2) The threaded components adopt a modular combination, including threaded conveying components, kneading components, shearing components,分流 components, toothed components, back-mixing components, etc., which can be arranged and combined according to any material process.
2. Gearbox:
1) The gearbox adopts a parallel type design with a parallel three-shaft structure, integrating减速 and torque distribution. The bearings are imported SKF bearings.
2) It also utilizes an oil-immersion lubrication system, equipped with low oil level and overpressure alarm systems to promptly remind customers to add or change oil, ensuring the gearbox's long-term and efficient operation.
3) The gearbox is cast from ductile iron material, increasing the rigidity of the housing, improving operational stability and safety factors, with overall reliability and load capacity enhanced by over 25%.
4) The screw speed is 600 rpm, enabling high-speed operation.
5) Gears: Precision grade 7 high accuracy, high-speed heavy-duty hard-toothed surface, material 20CrNi2MoA, HRC58—62.
3. The barrel is equipped with five temperature control zones. The heating for the first and third barrel sections uses cast copper heaters; the其余 sections use cast aluminum heaters. Barrel cooling adopts soft water循环 cooling, with the循环 cooling control electromagnetic valve using the Italian CEME5510 product.
4. The barrel is fitted with an integrated stainless steel protective cover, ensuring safety, aesthetics, and energy efficiency.
5. Utilizes a water-cooled strand pelletizing die head, with melt pressure and melt temperature sensors installed at the die head.
