PP Woven Bag Granulating Line
LIANGUAN high efficiency, one-step plastic recycling machine is designed for the reprocessing of PE polyethylene (HDPE, LDPE, LLDPE), PP polypropylene flexible packaging material (BOPP, OPP), PET film, printed and non-printed, and foamed material such as EPE EPP EPS, also filament, raffia, nylon, etc. This compactor integrated pelletizing system eliminates the need of pre-cutting the material, requires less space and energy consumption while producing high quality plastic pellets at a productive rate.
PP Woven Bag Granulating Line Main features:
1) Simple design, user-friendly operation.
2) Siemens original motors, ABB/Schneider converts.
3) Siemens PLC, Omron Temperature controllers, DELIXI air switch.
4) Lower investment cost for a high quality and durable machine.
5) Low energy consumption, High output capacity.
6) Engineers are available to do commissioning work abroad.
1. Belt conveyor
Plastic film, bags, filament, raffia are conveyed by belt conveyor up into the compactor. Hauling roller for feeding rolls of film. Speed adjusted by ABB/Schneider inverter.
Metal detecotor as an option, to detect and notify to remove metals.
2. Compactor Cutter / 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.
3. Plasticization (Extruder)
A specialized single-screw extruder applied to gently melt the pre-compacted material. The plastic scraps will be well melted, plasticized in the extruder. With double-zone vacuum degassing system, volatiles such as low molecular and moisture will be removed efficiently, especially suitable for heavy printed film and material with much moisture.
4. Melt filtration
The requirements on the filter technology depend on the characteristics of the input material as well as the planned use of final granules. Regular single-plate/piston double-station screen changer or non-stop double-plate/ piston four-station can be installed on the end of the extruder to present significan
5. 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.
6. Dewatering system
Advanced vibration sieve combining with horizontal centrifugal presents high performance of drying.
7. Electric control system
Siemens PLC intelligent control system, user-friendly operation.
International famous brands: Siemens, Omron, ABB, Schneider, etc.
