The process flow of preparing RDF (waste-derived fuel) through resource treatment of domestic garbage, waste textiles, cloth, leather, etc.:
1. Pretreatment and transportation
Waste textiles enter the processing line through a chain conveyor or a belt conveyor to achieve automatic loading.
2. Coarse crushing
The material is coarsely crushed by a double-axis shredder or an industrial waste crusher to reduce the large volume of material to a size suitable for subsequent processing.
‌3. Sorting and purification‌
‌Magnetic separation‌: Separate ferromagnetic metal impurities and recover metal resources.
‌Wind separation‌: Use airflow to separate light combustibles (such as fabrics and plastics) from heavy impurities (such as sand and gravel).
‌4. Fine crushing‌
The sorted combustibles enter the fine shredder and are further crushed into uniform particles of 50-100mm to meet the size requirements of RDF fuel.
5. Molding
Some processes will add RDF molding machines to compress the crushed materials into high-density particles or fuel rods for easy transportation and storage.
6. Finished product application‌
The final RDF fuel can be directly used in cement kilns, power plants, etc. to replace coal and realize energy utilization.
