The recycling process for PP (polypropylene) woven bags involves several steps, designed to convert waste bags into reusable plastic pellets. This process includes washing, drying, and pelletizing, ensuring the material is clean and ready for further manufacturing.

Process Description
Shredding and Crushing:

The first step involves feeding the PP woven bags into a shredder or crusher, which reduces the size of the bags into smaller, more manageable pieces. This is crucial for easier handling in subsequent processes.
Pre-washing:

The shredded material is then sent through a pre-washing system, where it is rinsed with water to remove larger contaminants like sand, dust, and other debris. This step helps to minimize wear and tear on the machinery used in the following steps.
Hot Washing:

The pre-washed PP flakes are subjected to a hot wash process. This involves immersing the material in heated water, often mixed with detergents or other cleaning agents, to remove oil, grease, ink, and other stubborn contaminants. The high temperature helps to ensure thorough cleaning.
Rinsing:

After hot washing, the material is rinsed with cold or clean water to remove any residual cleaning agents and contaminants. This step is essential to ensure the purity of the recycled material.
Friction Washing:

The material then undergoes friction washing, where high-speed friction within the washing unit further removes remaining impurities. This process is especially effective at eliminating fine particles and stubborn dirt.
Separation:

The washed PP flakes are passed through a separation tank where different densities cause contaminants like metals or other plastic types to be separated from the PP material. This ensures that only clean PP flakes proceed to the next stage.
Dehydration and Drying:

The clean PP flakes are dehydrated using a centrifuge or other dehydration equipment to remove excess water. Following dehydration, the material is further dried using hot air dryers to ensure it is completely dry before pelletizing.
Pelletizing:

The dry PP flakes are fed into a pelletizing machine, where they are melted and extruded through a die to form uniform plastic pellets. The pellets are then cooled and cut into small, consistent shapes suitable for reuse in manufacturing.
Cooling and Storage:

The pellets are cooled using air or water cooling systems and then collected and stored for future use in the production of new plastic products.
Uses
Recycling and Reuse:

The recycled PP pellets can be used to produce a variety of products, including new PP woven bags, packaging materials, automotive parts, and more, thereby reducing the demand for virgin PP material.
Environmental Impact:

The process significantly reduces plastic waste, preventing PP woven bags from ending up in landfills or the environment, and contributes to a circular economy by turning waste into valuable resources.
Cost Efficiency:

Recycling PP woven bags through this process lowers production costs by providing an alternative to raw materials and enables manufacturers to reduce their environmental footprint.
Product Quality:

The washing and pelletizing line ensures that the recycled material is of high quality, suitable for various industrial applications, and meets the standards required for producing new products.
This recycling line is widely used in industries focusing on plastic recycling, packaging manufacturing, and environmental protection.
