Core Product Features
- Upgraded plasticization quality via three-machine linked process: Different from traditional single-stage and double-stage granulating equipment, the 180-type three-machine structure realizes three core processes including segmented melting, fine filtration and stable extrusion. Plastics receive more uniform heat and pressure, completely solving common problems of film, mixed materials and scraps such as incomplete plasticization, raw granules and excessive black spots. The finished granules are plump and transparent with greatly reduced defective rate, meeting the production demand of high-quality recycled granules.
- High-frequency wear-resistant core accessories for stronger durability: Core extrusion components adopt industrial high-strength materials plus high-frequency heat treatment process. The 180mm-diameter and 1800mm-length 40CR alloy steel screw features high hardness, wear resistance and deformation resistance, which is not easy to be damaged when processing waste plastics with sediment and impurities for a long time. The 232mm-diameter and 1800mm-length 45# steel high-frequency treated barrel is high-temperature resistant and corrosion resistant, keeping undeformed under long-term high-temperature operation. The service life of accessories is increased by more than 30% compared with ordinary small equipment, greatly cutting operation and maintenance costs.
- Powerful constant-speed feeding for low-noise and stable transmission: Equipped with an upgraded forced feeding machine, matched with a 200-type hard-tooth surface reducer with thickened feeding teeth and a dedicated 22KW feeding motor. It features firm material biting and stable constant feeding, eliminating slipping, material blockage and material breakage of light film raw materials. The main machine is equipped with a 250-type hard-tooth surface low-noise reducer with precise gear meshing and low transmission loss. The overall operating noise is lower than 70 decibels, far better than industry environmental protection standards, adapting to daily silent production in factories.
- Segmented energy-saving heating for precise temperature control and power saving: Adopts an independent two-stage heating system. The main machine is equipped with 4 sets of 80KW electromagnetic heating modules with fast heating speed, high heat conversion rate and strong temperature controllability. The secondary machine is matched with 3 sets of 60KW heating rings for zoned precise temperature adjustment. Operators can fine-tune temperature parameters according to different plastic materials such as PE, PP and PS to avoid raw material scorching and degradation. It achieves remarkable energy-saving effect, saving more than 25% power compared with traditional resistance heating equipment.
- Small size with large output adapting to lightweight production: Equipped with a 37KW high-efficiency main motor and a 3-6KW adjustable speed head motor with stable and sufficient power output. The machine has a compact body, small floor area and convenient installation without complex infrastructure transformation. Modular design simplifies operation and maintenance with low operation threshold, enabling new operators to get started quickly. It perfectly adapts to lightweight scenarios including small processing factories, workshop production and factory scrap self-recycling.

Application Fields
This 180-type three-machine plastic pelletizing machine adapts to small lightweight plastic recycling processing scenarios. It is widely used for recycling granulation of waste plastic films, agricultural mulch films, woven packaging bags, plastic runner materials, injection scraps and small waste plastic containers. It mainly serves small plastic recycling workshops, start-up recycling enterprises, plastic product factory scrap self-recycling workshops and regional waste plastic processing sites. The high-quality recycled granules can be directly used for secondary production including injection molding, blow molding and extrusion molding, applied in daily plastic products, packaging, small building materials and other fields to realize efficient waste resource utilization.
Working Process
- Raw Material Pretreatment: Crush, clean and dehydrate waste plastics, scraps and film raw materials to remove sediment, oil stains and impurities, ensuring raw material cleanliness for uniform plasticization.
- Forced Feeding: 22KW motor matched with thickened hard-tooth surface feeding reducer realizes powerful and constant feeding, solving slipping and empty feeding of light film raw materials with stable and non-stuck feeding.
- Segmented Melting Plasticization: Realize gradual plastic melting via main machine electromagnetic heating and secondary machine heating ring zoned temperature control to ensure full plasticization without raw granules or scorching.
- Fine Filtration and Extrusion: The head motor drives melt extrusion stably, and multi-layer filtration removes impurities and black spots to guarantee pure and uniform melt.
- Cooling and Pelletizing: Strip-shaped melt is shaped rapidly via water cooling and air cooling, then cut into uniform granules by pelletizer.
- Screening and Warehousing: Classify finished granules, store qualified granules for standby, and reprocess a small amount of waste materials in the machine.
