Woven Bulk Bag Recycling

Woven bulk bag recycling machines can treat with pp woven bags such as rice bags, cement bags, etc. The whole bulk bag recycling machine process includes shredding, water rinsing, friction washing, dring by washing system; compacting, plasticization, pelletizing and drying by the pelletizing system. PLC intelligent system realized high automatic, the whole line just needs 3-4 man to operate. With over 20 years of experience in recycling, WANROOETECH not only mastered the key technology but also improved machine designs to address specific product features. WANROOETECH offers bulk bag recycling machines that are high output and low energy consumption.

Why Recycling Bulk Bags?
Currently, the PP material that bulk bags are made of is one of the most frequently used plastics for packaging. However, despite its prevalence and the fact that it can be melted and repurposed multiple times, it doesn’t often make it to recycling centers. Only about 1% of PP used worldwide is recycled, leaving the rest in landfills. The slow decomposition and incineration of PP harm the surrounding environment, releasing hazardous chemicals.

 

Reusing and recycling super sacks helps keep these harmful chemicals and plastics out of landfills and helps keep them circulating in manufacturing new products. It also benefits the environment in other ways. Manufacturing products from virgin materials call for a lot of energy consumption. By recycling PP and using it in blends, there is less of a need for those virgin plastics, which reduces energy use, sometimes by as much as 88%.

 

Lowering the need for virgin materials also helps conserve the finite resources used to manufacture PP plastics — namely, oil and propane gas. Recycled PP is versatile, making it suitable for use in manufacturing clothing and industrial fibers, containers, bins, dishware, speed humps, gardening tools and more.

 

Choosing to reuse and recycle bulk bags is essential to keeping PP and its chemicals out of landfills and reducing the number of energy manufacturers use. By giving your bags a second life, you’re reducing the impacts of manufacturing on the environment and helping preserve resources.

 

Woven bulk bag recycling machine selection guidance:
For the recovery of the woven bulk bag, it is necessary to determine the clean situation of the woven bulk bag. If the woven bag you recover is a clean waste, you can use double shaft shredder machine + woven bag granulator machine, or use double single shaft shredder machine + woven bag pelletizer granulator, double single shaft shredder, and the woven bulk bag will not be wound on the shredder shaft; if your recycled woven bag is dirty, then choose the woven bag washing machine + woven bag squeezing granulator machine.

 

How to recycling Bulk Bags?
Most modern bulk bags start as virgin PP plastic, made into woven fabric, then shaped or sewn to form bags. Because they are made almost entirely of plastic, the totes are fully recyclable and reusable. Not only do they last through multiple uses and environmental wear, but the PP material can be processed again and again without losing much structural integrity.

The entire woven bulk bag recycling machine is controlled via a central electric control panel and cabinet. Each piece of equipment is connected using conveyors.

 

Plastic Shredder Machine: As long pieces of woven bulk bag easily tangle (imagine saran wrap) and clog conveyors and rotary-based machines, the first step is to cut the woven bulk bag into smaller pieces using a plastic shredder machine. The resulting plastic pieces from the plastic shredder is around 1-5 inches.

 

Wet Plastic Granulator: The plastic granulator cuts the woven bulk bag into even smaller pieces approximately 10-20mm in size. With water constantly injected into the cutting chamber, our wet granulation process also “pre-treats” and partially cleans the woven bulk bag before moving on to the next machine.

 

Friction Washer: A high-power washing machine, our cold water friction washers spins at nearly 1,000 rotations per minute. As the woven bulk bag enters the friction washer, the woven bulk bag rubs against each other at high speeds getting rid of hard-to-remove contamination. At the same time, any paper and cardboard is broken down into fibers and removed. While one friction washer is standard, various washing plants have requested a secondary friction washer to ensure thorough cleanliness.

 

Sink Float Separation Tank: Using water as a medium, materials that float are separated from materials that sink. In the case of woven bulk bag recycling will float while heavier contamination such as dirt, sand, glass, metals, and other plastics will sink. A screw conveyor at the bottom of the sink float separation tank removes the contamination. While separation is one aspect of this apparatus, a secondary function is to further clean the plastic film.

 

Centrifugal Dewatering Machine: The first step in the drying process, our centrifugal dewatering machine uses centrifugal force to remove a large portion of water within the woven bulk bag before moving forward onto the thermal dryers. As thermal dryers use heat to dehydrate water, it requires more energy consumption during operation. Hence, the use of the dewatering machine is beneficial in savings for long-run operations costs.

 

Screw Press Dewatering Machine: An optional piece of equipment, the screw-press dewatering machine is a more advanced version of the standard dewatering machine. Instead of using centrifugal force to remove water from the woven bulk bag, the screw press squeezes the water out via high pressure. This machine can actually take the place of both the dewatering machine and thermal dryers.

 

Thermal Dryer + Cyclone Separator: The clean woven bulk bag is vacuumed out of the dewatering machine and into the thermal dryer system where it’ll travel down a series of stainless steel tubes mixing with hot air. The remaining moisture is dehydrated in this process which ends with a cyclone separator. The cyclone separator allows the plastic film to mix with a fresh stream of cold air which prepares it for storage into the product silo. The cyclone separator is also effective in removing fines and such dust.

 

Product Silo: A storage tank for the clean, dry pieces of woven bulk bags.

 

Plastic Pelletizing Machine: The final step in woven bulk bag recycling and maybe the most important, the clean film needs to be processed into plastic pellets before it can be used in production. To do so, we offer a specialized woven bulk bag water ring pelletizer system that produces beautiful round plastic pellets.
