Import substitution twin-screw extrusion granulator, easy to clean and durable.

I: SHJ-45 Twin-Screw Extrusion Granulator | Twin-Screw Granulator Manufacturer is primarily used for the filling, enhancement, chlorination, and processing of polypropylene and superabsorbent polymers in rubber, plastic, and engineering resins.

II: Working Principle of SHJ-45 Twin-Screw Extrusion Granulator | Twin-Screw Granulator Manufacturer:
Material enters through the feed port and, under the action of the rotating screws, is kneaded into clusters and propelled forward along the screw channels. Due to the shearing, compression, and mixing effects of the screws, the material undergoes further blending and plasticization. Temperature and pressure gradually increase, resulting in a viscous flow state. The material is then extruded through the die head under specific pressure and temperature conditions, ultimately forming products of the desired shape.

III: Main Configuration Description of SHJ-45 Twin-Screw Extrusion Granulator | Twin-Screw Granulator Manufacturer
1. Screw Elements and Core Shaft
1) The screw and core shaft are connected via involute splines. The modular barrel is made of wear-resistant bimetallic material, lined with α-101 hard alloy sleeves. Screw elements are crafted from wear-resistant high-speed tool steel W6Mo5Cr4V2 ( 6542), while the screw core shaft is made of 40CrNiMoA material. The first barrel section features a main feed port, the third section includes a glass fiber port with a blind plug, the fifth section has a vacuum vent port, and the remaining barrel sections are closed.
2) The threaded components are modularly assembled, including conveying elements, kneading elements, shearing elements,分流 components, toothed elements, and back-mixing elements, which can be arranged and combined according to any material process.
2. Gearbox:
1) The gearbox adopts a parallel design with a three-shaft configuration, integrating减速 and torque distribution. It utilizes imported SKF bearings.
2) An oil immersion lubrication system is employed, equipped with low oil level and overpressure alarm systems to promptly提醒 customers to add or change oil, ensuring long-term and efficient operation of the gearbox.
3) The gearbox is cast from ductile iron material, enhancing rigidity, operational stability, and safety factors. Overall reliability and load capacity are increased 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-faced gears, made of 20CrNi2MoA, HRC58—62.
3. The barrel is divided into five temperature control zones. The second and third barrel sections use cast copper heaters for heating; the其余 sections use cast aluminum heaters. Barrel cooling is achieved through soft water circulation cooling, with循环 cooling control electromagnetic valves using Italian CEME5510 products.
4. The barrel is equipped with a stainless steel integrated protective cover, ensuring safety, aesthetics, and energy efficiency.
5. A water-cooled strand pelletizing die head is used, with melt pressure and melt temperature sensors installed at the die head.
