Application Areas:
PE/PP plastic film washing line of Wanrooetech is capable of processing a wide range of hard and soft plastic waste, for example, agricultural films, greenhouse films, package films and bags,Big bags (Raffia)， HDPE/PP bottles, barrels, box, etc.
Description:
It is mainly used to recycling the waste PP/PE film and woven bags..etc. The production line including the conveyor belt, metal detector (optional), wet crusher, floating washer, high speed friction washer, centrifugal dewatering machine, drying system and material collecting.
We have special crusher, grinder machine for the film, sack with special blades design; so the output material is smaller size but capacity is higher; It will help washing the materials more clean, and save labor cost and energy.
You can also choose use the shredder machine to reduction the material size, it’s according to your requirements, if use the shredder, the blades will lasting longer time and save blades changing labor cost.
This production can come with the plastic baler machine, to produce the plastic bales easy for transportation. Can also come with Squeezing Pelletizing Machine, to dry the materials and make granules. Instead of dewatering machine, drying system and agglomerator. Saves cost, it is an energy saving equipment.
We also have the trammel machine use to screening out the inside sand, rocks from the material.
We provide effective, customized proposals and cost-effective solutions by listening to and understanding our customer’s needs.
Process Flow:
NO | Process | Machine | Description |
1 | Send the film and bags to the wet crusher machine | Conveyor with Metal Detector(Optional) | It separates impurities such as metals in the films and bags,Send the materials to the wet crusher machine |
2 | Cuts the films and bags into small pieces size | Wet Crusher Machine | A wet crusher cuts the PP / PE film into small pieces approximately 10-20mm in size and moving onto the next piece of equipment. |
3 | Send the films and bags to the Floating Washing machine | Screw Feeder | Put the films and bags into the Hot washer to clean |
4 | The first time Floating wash the bags and films | Floating Washing Tank | As the PP / PE films enters the friction washer, the plastic film rubs against each other at high speeds getting rid of hard to remove contamination. |
5 | Feeding bags and film scraps to friction washer | Screw Feeder | Put the films and bags into the High-speed Friction Washer to clean |
6 | Separate the contamination from film and bags | High Speed Friction Washing Machine | After crushing material from enters the mouth, through the high speed on the axis of the blade flap and spray water to the common function of good cleaning effect. |
7 | The second time Floating wash the bags and films | Floating Washing Tank | It used in cleaning film and bags,make the film cleaner. |
8 | Dry the film and bags | Dewatering Machine (卧式) | The dewatering machine uses centrifugal force to spin water moisture off the films and bags. |
9 | Hot air to dry the films and bags | Pipeline Dryer | Using the hot air to take the humidity away from the clean material. |
10 | Storage dry pieces of films and bags | Storage silo | A storage tank for the clean, dry pieces of PP PE films and bags. |
11 | make film and bags into granules (Optional) | Pelletizer / Extruder | We offers both single-screw extruders and twin-screw extruders. Based on your requirements, we offer both one-stage and double-stage pelletizing setups where granules can be formed using a granulator or water-ring cutting. |
Features:
The PE/PP Film system is designed for washing films with contamination levels exceeding 80% Minimizing the recycling water flow rate and evaporation losses.
The pre-treatment module of the system is equipped wear resistant design to maximize system up time.
Pre-shredding and pre-washing system removes a large percentage of abrasive materials (sand, grit etc.) to protect the rest of the system.
Shredding system is designed specifically for film materials to create a uniform particle size which is easy for washing and drying.
High speed washing system optimized according to the specific material type liberates and separates contamination from film flakes.
Mechanical (centrifugal and squeezing) and thermal drying systems control the moisture content of the finished product. At < 5% moisture the material is suitable for high quality pelletizing.
Shredding, high speed washing and drying stages are optimized to avoid over processing which can cause material loss (fines creation).
