Refuse-derived fuel (RDF) is a type of fuel produced from various types of waste such as municipal solid waste (MSW), industrial waste, and commercial waste. It is used as an alternative energy source in incinerators, cement kilns, and power plants.

RDF shredders can process a wide range of waste materials including plastics, paper, cardboard, textiles, rubber, wood, and other combustible materials. Non-combustible materials such as metals, glass, and stones are typically removed during the screening and separation stages.

Double-shaft shredders are robust and efficient machines designed to handle large, bulky waste items. They operate at low speeds with high torque, which allows them to process tough materials and produce consistent particle sizes, essential for high-quality RDF.

The typical output size for RDF produced by double-shaft shredders is about 5 cm. This size is suitable for efficient combustion in various energy recovery systems.

The maximum capacity of a well-designed RDF shredding production line can exceed 20 tons per hour. This capacity depends on the specific design and configuration of the shredders and associated equipment.

Non-combustible materials are removed using various screening and separation technologies:

• Trommel or Vibrating Screens separate materials based on size.
• Magnetic Separators remove ferrous metals.
• Eddy Current Separators remove non-ferrous metals.
• Air Classifiers separate light materials from heavier ones.

The stages include:

Pre-Shredding: Initial size reduction using a primary shredder.

Screening and Separation: Removing non-combustible materials.

(Optional) Intermediate Shredding: Further size reduction.

Fine Shredding: Achieving the desired particle size.

Storage and Handling: Storing and transporting the RDF.

Dust control is crucial to ensure a safe working environment, prevent fire hazards, and reduce air pollution. Dust suppression systems are installed at key points in the production line to minimize airborne particles.

Modern RDF production lines use automated control systems for efficient operation and monitoring. These systems can include sensors, control panels, and software to manage the shredding process, ensure consistent quality, and optimize performance.

Safety measures include the installation of safety guards, emergency stop mechanisms, regular maintenance protocols, and training for operators. Ensuring compliance with safety standards and regulations is essential to prevent accidents and ensure smooth operation.

Shredded RDF is typically stored in silos or bunkers. It can be transported using conveyors and feeders to storage areas or directly to end-use applications like incinerators or cement kilns. Proper handling ensures efficient logistics and consistent fuel supply.

Every year, a large amount of industrial waste, municipal waste, and garden waste are produced around the world. Encouragingly, many of these waste resources have the potential to be converted into useful derived fuels through recycling. However, the prospect of recycling and reusing these fuels still faces challenges, including issues such as technology cost, infrastructure construction and policy support. Therefore, Shengzhong Company has developed and designed a set of derived fuel recovery solutions.
