RDF Shredders( Single and Multistage Shredding)

Refuse-Derived Fuel (RDF) is an eco-friendly alternative fuel derived from waste materials, widely used in industrial boilers, rotary kilns, and other high-energy applications. Utilizing RDF not only reduces dependence on fossil fuels but also minimizes landfill space requirements—achieving sustainability goals while managing waste effectively.

RDF can be produced from a diverse range of waste materials, including municipal solid waste (MSW), household garbage, industrial and commercial waste, as well as construction and demolition debris.

  1. RDF shredding is a seemingly simple but challenging task. Due to the unpredictability of the material, the following types of industrial shredders are usually used for RDF shredding: Double-Shaft Shredder Four-Shaft Shredder Single-Shaft Shredder Pre Shredder Double-Rotor Shredder
  2. For RDF production, the raw material in most cases comes from municipal solid waste. WEIMA offers the right shredders for this first process step, shredding, with working widths of up to three meters, many heavy duty options and drive concepts specially designed for these applications. The result: safely and cleanly processed, homogeneous material streams. MSW Waste Shredder A double-shaft shredder pre-shreds municipal solid waste for the production of refuse-derived fuels (RDF). Secondary shredding happens with a single-shaft shredder.
  3. For industrial and commercial waste, it is usually simple to convert them into RDF because they usually have high calorific value and simple composition. In this case, a single-shaft RDF shredder can do the job. In particular, GEP ECOTECH's GS330 and GS320 series heavy-duty single-shaft shredders are designed for large-volume shredding, reliable, stable and energy-efficient.

  4. Light materials in demolition waste, such as plastics, paper, and waste wood, are also very good RDF raw materials. GEP ECOTECH's RDF recycling solution can process construction and demolition waste, recycle aggregates, light materials and metals, and make light materials into high-quality RDF/SRF.

  5. In some economically developed regions, there is another very common RDF raw material, which is waste from the fashion industry. They either come from waste, scraps, or obsolete products in the manufacturing process. The main components of these wastes include various cotton, linen, woolen fabrics, chemical fibers, etc. They have high calorific value and are very suitable for making RDF/SRF fuel.

  6. As we know, RDF/SRF mainly comes from municipal solid waste, industrial and commercial waste, light materials, fabrics, plastics, etc. However, in the field of alternative fuels, there is another material that is deeply loved by cement kilns, power plants, etc. because of its high calorific value properties like coal. This is TDF - an alternative fuel made from scrap tires. The process of producing TDF is simple - shredding the scrap tires, and an optional process is wire separation: separating the wire from the rubber to obtain higher profits. GEP ECOTECH's TDF production solution mainly includes a high-shear double-shaft shredder or a four-shaft shredder. In addition, GEP ECOTECH's tire recycling solution can also produce rubber particles and rubber powder, just by adding the corresponding equipment.
