Overview of Woven Bag Washing Machines

А woven bag washing machine is an advanced industrial recycling system designed to process and recycle polypropylene (PP) woven bags, jumbo bags, and similar plastic materials. These machines play a key role in reducing plastic waste by converting used woven bags into clean plastic flakes or pellets, which can be reused in the production of new plastic products.

Key Features and Process Flow

🔹 Shredding and Size Reduction

The recycling process begins with feeding the waste woven bags into shredders or crushers. These machines break down the bags into smaller pieces or flakes, which significantly improves the efficiency of subsequent washing and drying steps.

🔹 Cleaning and Washing

Next, the shredded material passes through a series of washing units, such as friction washers и floating washers. These remove dirt, sand, labels, and other contaminants. The washers are typically made of stainless steel and use a combination of water and mechanical agitation to ensure thorough cleaning.

🔹 Separation and Impurity Removal

The system includes magnetic separators, бубњеви, and other sorting devices to eliminate metal particles, stones, and other non-plastic impurities from the plastic flakes.

🔹 Dewatering and Drying

After washing, the wet plastic flakes are processed through centrifugal dewatering machines, followed by hot air dryers или центрифугалне сушаре. These systems reduce moisture content to around 5–8%, making the material suitable for further processing.

🔹 Storage and Pelletizing Preparation

Clean, dry flakes are then stored in silos or buffer tanks, ready for downstream applications such as extrusion or pelletizing. This final step transforms the recycled flakes into high-quality plastic pellets that can be reused in manufacturing.

🔹 Intelligent Control Systems

Modern woven bag washing lines come equipped with smart control systems to monitor and adjust key parameters—such as temperature, water flow, and system pressure—ensuring stable operation and easy maintenance.

Апликације

Woven bag washing machines are widely used in plastic recycling plants around the world, especially in regions with high volumes of PP woven bag waste, such as Southeast Asia, India, and China. These systems help manufacturers and recyclers turn post-consumer waste into valuable raw materials.

Резиме

A woven bag washing machine is a comprehensive recycling solution designed to clean, sort, and process used PP woven bags into reusable plastic flakes or pellets. By integrating multiple stages—shredding, washing, drying, and sorting—this system supports efficient plastic recovery and contributes to sustainable development and circular economy goals.
