RDF Processing Plant Features

A RDF processing plant consumes solid waste and generates RDF(Refuse-derived fuel) or SRF(Solid Recovered Fuel) or TDF(Tire-derived fuel).

The RDF(refuse-derived fuel) mainly consists of combustible components, with the non-combustible components removed during processing, and this fuel can then be incinerated to produce heat energy. Diverting waste from landfill and creating an alternative energy for fossil fuels.

RDF Manufacturing Process (How is RDF produced?)

The RDF production process is various based on the compostion of the infeed materials. The following are the major steps of a RDF Processing Machine producing RDF alternative energy.

1. Sorting
2. Coarse Shredding
3. Magnetic Separation
4. Air Classifier
5. Fine Shredding
6. Briquetting

The RDF Processing Plant comes with dust filtration and air circulation as the RDF production generates excessive odour and dust.

Coarse Shredding (RDF Shredder)

RDF Shredding delivers by a twin shaft shredder or a pre-shredder. They share a similarity: extremely high torque and low speed. The goal of this step is split-opening waste in bags and destroying the exterior of the waste. Most of the waste is downsized and disintegrated to 100mm by 100mm (4 inches by 4 inches) at the end of this process.

If the infeed materials contain excessive bags or bales, prior to twin-shaft shredder, a pre-shredder is required for the early treatment in a RDF Processing Plant.

Magnetic Separation

Multiple 2500Gs+ magnetic separators operate throughout the system. Metals are typical by-products and shall be sorted out as early as possible. The absence of metal contaminants will prolong the overall machine service life.

2 overband metal separators are immediately used after coarse shredding (RDF Shredder).

Air Classifier (Air Blade)

Plastic, wood, paper, cardboard, foam and textile that contain high caloric value are usually light weighted. That is why RDF Production Plant needs air classifier to keep away heavy items like concretes and scrap metals, bringing up a high caloric value.

Fine Shredding

The goal is to achieve 50mm by 50mm (2 inches by 2 inches). From 100mm to 50mm, it is essential before briquetting and for final RDF quality. The particles are re-shredded by a high-speed and wide-chamber single shaft shredder (RDF Crusher). Inside the shredder, a rotor up to 3 meter long maximize the shredding area.

The hex screen combined with multiple rotor blades on the rotor ensure homogeneous particle sizes and stable capacity. The front doors are easy to access for removal of tramp materials.

In some cases where the infeed materials are homogeneous and not challenging, a P/T/M series shredder with a hydraulic pusher is sufficient produce RDF.

Briquetting

In RDF Processing Plant, the briquetting machine convert of RDF into uniformly shaped briquettes that is easy to use, transport and store. Mostly important, the RDF cudes are densified and thus increases caloric value/volume.

Before and After

Once a RDF processing plant is finished, Wiscon tests it with municipal solid waste (MSW) and commercial and industrial (C&I) waste to show capability and output. As a RDF recycling equipment supplier, we’re dedicated to a zero waste to landfill approach, as well as using our state-of-the-art RDF Processing Machine to extract energy from processed waste.
