Plastic Film Pelletizing Machine
The production line adopts European design and advanced technology. It is mainly used for clean PE PP films, scraps and crushed, washed, dried HDPE/LDPE/PP materials. The material is sent to the compactor cutter through the conveyor belt, and fed into the single screw extruder by high speed rotation of the compactor cutter;...
Material shape: Woven bags, pp pe film,printed LDPE film (rolls, loose, bundled), agriculture film, foamed plastics and raffia, etc.
Note: depending on material property, various downstream equipments are available.
Plastic Film Pelletizing Machine Advantages
1. Suitalbe for plastic film PP ,PE ,HDPE,LDPE,LLDPE and so on.
2. Equipped with the vertical and horizontal hopper feeding device to ensure high output.
3. Vent design on the barrel to evaporate the volatiles form the recycle material.
4. Hydraulic screen change unit and pressure gauge for easy operation and safety.
5. Water chamber with die face cutter simplifies the process.
6. The vertical centrifuge separates and dry the pellets faster.

Introduction:
Waste plastics are usually granulated by single-screw extruder or twin-screw extruder. The plastic debris prepared in the early stage is added to the extruder, and granulated by melting, plasticizing, filtering, mixing and exhausting.
The granulator is composed of extrusion system, transmission system and heating and cooling system. The extrusion system consists of screw, barrel, hopper, die-head. Waste plastics are plasticized into a uniform melt through the extrusion system. Under the pressure established in the process, the screw is continuously extruded to the die-head. Material needs to be filtered to extrude granulation after melting in the barrel. The filter device has a filter or a filter screen. Some filtering equipment can ensure continuous production without shutdown. The filtered material flows to the machine head and granulating device for granulation.
Common methods of pelleting: hot pelleting and cold pelleting
Hot granulation can be divided into underwater, water mist, water ring, air-cooled and hot granulation.
Cold-cut pellets are divided into flat-plate cold-cut pellets and draw-bar cold-cut pellets.
The underwater granulation equipment is suitable for the granulation of PE, PP, PS, PVC and other materials. It consists of the underwater granulator head, warm water circulation system, separation system and screening system. The underwater granules are beautiful and uniform in shape, not easy to bond, high in output, good in sealing and good in particle quality. However, the overall equipment is huge and complex, which requires a lot of energy and requires high operating conditions.
Water ring granulation is suitable for EVA hot melt adhesive, TPU elastomer, cable material and other physical miles. It consists of water ring granulator head, warm water circulation system, separation system, screening system and so on. Its advantages and disadvantages are the same as underwater granulation. Air-cooled hot granulation is suitable for thermoplastic and engineering plastics. The particle shape produced is generally cylindrical or waist drum, with simple equipment structure and low power consumption. The tool wear is small and the particles do not need to be dried. The disadvantage is that there may be adhesion between particles. The melt flow rate should not be too fast, so the output is relatively low.
Drawing strip cold-cut granules are suitable for polyolefin, nylon and other plastics. The granules produced are generally cylindrical. They have simple equipment structure and convenient operation and maintenance. The main drawbacks are large power consumption and serious tool wear.
The noise produced by equipment operation, the amount of dust produced during granulation and the size of odor are also the necessary hardware conditions for purchasing.
