Experts from the twin-screw extruder service provider Nanjing Jieente Electromechanical Co., Ltd. said that the heat transfer of the power transmission and the external heating element is carried out by solid conveying, compaction, melting, shearing, and kneading extrusion of the plastic. The material is forced into the main screw by the air-cooled hot-cutting granulator, and the material is subjected to mixing and plasticization under the action of compression and shearing and external heating of the screw. The temperature and pressure are gradually increased, showing a viscous flow state, and passing through the handpiece and extruding the pellet at a certain pressure to obtain particles of a desired shape.
 
Experts from the twin-screw extruder service provider Nanjing Jie Ente Electromechanical Co., Ltd. said that the air-cooled hot-cutting granulator is mainly used for filling, blending and modifying rubber and engineering resins. Degradable masterbatch, polyamide polycondensation, extrusion of polyurethane polyaddition reaction, granulation of carbon powder, magnetic powder, insulation for cable, sheath material, PVC cable material and preparation of various silane cross-linking materials.
 
Twin-screw extruder experts say that the air-cooled hot-cutting granulator is suitable for plastic granulation such as PVC.EVA. Elastomer high-speed granulation plant equipment (air-cooled, water-cooled) features:
1. The production line integrates mixing, conveying, feeding and extruding materials, and the air is sent by hot-cutting and cooling. The automation is continuously determined, the production efficiency is high, and the plasticizing and mixing effects are good.
2. The air-cooled hot-cutting granulator is compact in structure, small in footprint and space, and easy to install.
3. The production process is carried out in a closed-loop temperature control. The mixing, feeding, and extruder have their own heating and cooling systems, and the respective temperatures are controlled according to the process requirements.
4. The feeding mechanism adopts the propeller double-pull type and has strong feeding ability. It is especially suitable for the extrusion of pelletized materials which are directly mixed by an internal mixer.
5, the barrel screw is made of 38CrMOALA high-quality alloy steel, after nitriding treatment, high hardness, wear and corrosion resistance /
6. The machine head adopts manual network change or automatic non-stop automatic screen change mechanism to improve production efficiency.
7. The air-cooled hot-cut granulation electrical control system adopts advanced PLC control technology and is composed of multiple frequency converters, so that multiple machines such as feeding, extrusion and pelletizing can be made with high precision and wide range of steps. Speed regulation. And with the whole machine process chain, sound and light fault alarm and other functional control, perfect and reliable.
