Features and application of single screw granulator
Features of single screw granulator
1. The single-screw granulator integrates compaction, conveying, feeding, extrusion, air-cooling and hot-cutting, and air-cooling to complete automatic continuous operations. Such a single-screw granulator has high production efficiency;
2. The single-screw granulator has internal mixing, feeding and extrusion sections, and electric heating or steam heating or hot oil circulation heating technology can be selected according to the customer's choice. According to its temperature control requirements, according to the different materials to be produced, the temperature is adjusted. The requirements are also different.
3. The mixing machine adopts the technology of 'four-edged synchronous wear-resistant mixing chamber', which has high efficiency, low energy consumption, sufficient plasticization and uniform dispersion;
4. The feeding equipment adopts the company's unique technology, which can assist in the mixing of the mixed materials, and force-feed the single-screw extruder to improve the granulation efficiency and quality;
5. Both the double-cone screw and the single-screw drive adopt the communication frequency conversion technology, which can be used to various technical skills requirements;
6. The front part of the machine head adopts hydraulic quick screen changing equipment, which saves time and effort and is environmentally friendly;
7. The granulator adopts rotary cutter head and fine-tuning equipment for air-cooled hot granulation;
8. The cooling of the pellets is carried out by cyclone separator, roller cooler or disc vibrating screen;
9. The electronic control system adopts PLC, visual interface and frequency conversion technology to complete the whole process of automatic control.
Scope of application
Single-screw extruding unit is mainly used for filling, blending, modifying, adding, chlorinating, polypropylene and superabsorbent resins of rubber, plastics and engineering resins; degradable masterbatch, polyamide polycondensation, polyurethane adding Extrusion of polymerization reaction; granulation of carbon powder and magnetic powder; preparation of insulating material, sheath material for cables, low-smoke halogen-free flame retardant PVC cable material and various silane cross-linking materials, etc. Small models are mainly used for scientific research and teaching
