Pp pe film washing production line

Types of PP PE film washing production lines

There are three main types of PP PE film washing production lines based on the feeding or input method used to process different types of films and materials. These types are defined by the way in which films are fed into the production line for washing and recycling.

• Automatic PP PE film washing production line

  An automatic PP PE film washing production line is a fully automated system that washes and recycles plastic films, such as polypropylene (PP) and polyethylene (PE) films. These films are commonly found in packaging materials, agricultural films, and industrial films. The primary purpose of an automatic PP PE film washing production line is to remove contaminants from the plastic film and convert it into clean, recycled material that can be used for manufacturing new plastic products.

  Typically, the production line consists of several key components, including a film feeder, washer units, float separators, a granulator or pelletizer, and a storage system for the recycled plastic pellets. The film is automatically fed into the washer, where it is cleaned through a series of washing and rinsing processes. Contaminants are removed from the film, and the cleaned film is dried before being granulated into plastic pellets. These pellets can then be stored for future use in manufacturing.

• Manual PP PE film washing production line

  A manual PP PE film washing production line refers to a type of plastic film recycling process that requires some degree of human intervention or manual operation. Unlike fully automated systems, a manual production line may involve basic machinery where workers perform specific tasks to feed, wash, rinse, and process the plastic film waste. In general, it is less efficient and productive compared to the automatic type.

  In a typical manual film washing line, operators may be responsible for sorting different types of plastic films, removing contaminants, feeding the films into washing equipment, monitoring the washing process, and performing basic maintenance tasks when necessary. While the manual production line can still be functional and helpful in recycling plastic film waste, the manual operation typically makes the workflow slower than washing lines with full automation.

• High-capacity PP PE film washing production line

  A high-capacity PP PE film washing production line is designed to handle larger film inputs and produce more recycled materials in a shorter time. The primary function of this type of production line is to wash and recycle plastic film waste made from polypropylene (PP) and polyethylene (PE) on a higher capacity scale to meet larger industrial and commercial demands.

  The main features of a high-capacity film washing production line may include bigger film feeders, powerful washer units, float separators, granulators or pelletizers, and storage systems for the recycled plastic pellets, among others. Premium and heavy-duty features and components are used to accommodate the larger throughput, ensuring efficient washing, drying, and pelletizing of the plastic film. Basically, it can support the processing of higher quantities of plastic film waste, catering to larger-scale recycling operations and industrial requirements.

Specifications and Maintenance of PP PE Film Washing Production Lines

Considering the importance of proper maintenance of waste plastic film washing lines to ensure their efficient operation and the consistent production of high-quality recycled materials, here's a brief description of a set of maintenance tips and routines for each key component.

• MACHINE FRAME, RECYCLING CRUSHER, AND SINK BATH TANKS:

• - Use industrial-grade plastic film waste cleaning solutions to wipe all frames, sinks, tanks, crushers, and hoses thoroughly.

• - Carry out a visual inspection routine to see if there are any loose, damaged, or missing parts occurring across these machine components. Worn-out conveyor belts should be replaced immediately.

• - Ensure that all bath sink and tank parts are de-scaled to avoid any obstruction in the waste recycling process.

• - Grease all moving machine components that are friction-prone to help ease movement.

• - Ensure that the entire frames, sinks, tanks, crushers, hose, and pump motor components are corrosion-free and resistant to moisture that may cause rusting.

• - Carry out periodic checks to ensure no water leaks in the production line film washer occur.

• FLOATING DRUM SCRUBBER AND AIR DRYER:

• - Conduct a functional test to confirm whether the floating drum washer and the air dryer are operating effectively on schedule once they are started up.

• - Carry out physical inspections to observe both pieces of equipment for any signs of unusual vibration, noise, or overheating.

• - Ensure that all filters are cleaned or replaced following the manufacturer's instructions so as to ensure optimal filtration and drying functions.

• - Lubricate all moving parts of both the floating drum washer and the air dryer as per the manufacturers’ direction so as to reduce the wear and tear on these components.

• - Keep both the floating drum washer and the air dryer free from waste, debris, and plastic film residue that may accumulate, and monitor the performance of the washer detergent and that of the drying fan too.

• SUPPORTING HOPPERS AND SCREW EXTRUDERS:

• - For all supporting hoppers and screw extruders, carry out a preventive maintenance schedule as per the manufacturer’s maintenance and servicing requirements.

• - Ensure that the electrical connections, fasteners, and seals are checked regularly and that there are no leaks in the pipeline and the hopper silo part.

• - Lubricate the sliding and pivoting components of the screw feeders and motors as per the prescribed instructions so as to avoid friction-induced wear and tear and to ensure smooth obstruction-free operations.

• - More importantly, remove the residual plastic film waste from both the hopper and the screw feeder to prevent any form of bridging and material back flow that may occur over time.

• SANITISATION:

• - For preventing any form of contamination and the further build-up of plastic waste residues, it is very important to routinely sanitise all the components of plastic film recycling washer machines mentioned above every week.

Ultimately, in order to further extend the overall service life of the plastic film washer production line and its individual machine components as well as to prevent any reoccurring plastic waste holding-up issues from occurring, it will also be crucial to frequently train operators on machine maintenance knowledge and best practices.
