LDPE Film Granulating Line

LDPE film granulating line is mainly used for plastic film, woven bags and other waste plastic recycling granulation, fluffy film material through the dense bin cutting compaction can effectively dry the material moisture, compaction.

LDPE Film Granulating Line Description:

LDPE film granulating line is mainly used for plastic film, woven bags and other waste plastic recycling granulation, fluffy film material through the dense bin cutting compaction can effectively dry the material moisture, compaction. The self-friction material is fed into the extruder screw at high speed after heating and pre-shrinking, which improves the output and saves energy consumption. The whole line adopts high torque gear box and PLC linkage control system. At the same time, it is convenient for unified and centralized management.
For materials of different shapes, different feeding methods are adopted: for materials of different properties, the corresponding screw structure is set up. After one or more net changes, can better remove impurities. Water ring granulator makes the appearance of particles to be greatly improved, centrifugal dehydrator and air drying system to produce particles without water.

LDPE Film Granulating Line Applications:

1. LDPE film granulating line has good effect on problems such as large water content and impurity in materials;
2. Because the two machines are equipped with exhaust device and network filter device can be heated after the material gas discharged many times, and after two filtration can be filtered out of the material impurities, so that the particles made more solid, smooth and pure.
3. Hydraulic lifting of the die head can make the host machine change the filter screen without stopping and improve production efficiency.
4. Reducer: high torque design; No noise, smooth operation.
5. Special screw design, so that the mixing effect is better, better dispersion effectively improve the problem of black spots and color difference.
6. According to the particularity of the material can choose forced feeding device and oil pressure fast network device, so that higher capacity, less power consumption.
7. Vacuum or ordinary exhaust system, is conducive to the discharge of water gas, waste gas, impurities; The discharging material is more stable, and the colloidal quality is stronger.

Film Granulating Line Work Process:

Plastic → Belt Conveyor → Metal Detector (Optional) → Compactor / Compactor → Extrusion → Hydraulic Screen Change → Die Head → Cooling Water Tank → Centrifugal Dehydrator / Dewatering Vibrating Screen → Dewatering Fan → Storage Silo

LDPE Film Granulating Line Detail:

  • Extruder
    A specialized single screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in a 36D processing section. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiency, especially suitable to heavy printed film and material with water content

  • Compactor / Agglomerator
    The rotatory blades of compactor will cut up incoming scraps. Frictional heating which caused by high speed rotatory blades will heat and let scraps shrinking just below their agglomerating point. Optimal designed guide structure compacts the material and directs it into extruder screw. Crushes, dries and compacts the material which enables a fast and stable feeding from the compactor directly into the extruder.

  • Belt Conveyor
    As standard design, plastic scraps such as film, filament, raffias conveyed into the compacting room through belt conveyor; to handle rolls’ scraps, roll hauling off device is an optional feeding method. Motor drives of conveyor belt and hauling device cooperate with ABB inverter. Feeding speed of conveyor belt or roll hauling off is fully automatic based on how full the compactor’s room is. Metal detector can be combined with belt conveyor, and can interlock with contrl system, to warn and stop the system, in case that metal is found in feeding.

  • Water-ring Die-face cutting system
    Water-ring die-face/Strand cutting methods are usually adopted. In water-ring die-face cutting system, the rotary cutting blades will be pneumatically fit completely and closely to the die-face surface to ensure efficient cutting. Rotary speed of the blades is automatically adjusted by module system according to melt pressure at the die face.

  • Vibration drying system
    Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.Combine crushing, compacting and plletizing steps in one system, less-labor cost.Higher efficiency feeding, suitable to film, filament, raffia, foaming materials;Higher output and lower energy consumption
