- About us
Pre-shredding brings the input material to a uniform size, which in some cases is already the right size for fuel, and eliminates overlengths, which would interfere with further processes.
Separation removes contraries and recyclable materials from the fuel fraction.
Fine shredding brings the fuel fraction, now free of contraries, to the right particle size. Optional post-screening makes sure that the particles do not exceed the maximum size for fuel use.
The process starts with a Terminator single-shaft shredder, whose shredding performance is configured for the input material. The contrary resistance of the shredder lets it accept a wide range of input materials, while the even intake ensures a consistent supply of shredded material to the downstream process steps.
If there is substantial organic content in the input material, it will need to be removed before further processing. The machine used for this is either a stationary Komptech drum screen or Flowerdisc disc screen.
The Ballistor’s separation function enables splitting of the material stream into three fractions – flat (2D), cubic (3D) and fine. The 2D fraction consists largely of high-caloric, contrary-free materials that is further processed into fuel. The 3D fraction contains readily separable recyclables (metals etc.) that can be reclaimed for recycling.
The 2D fraction is post-shredded to the grain size specified by the customer. Since the contraries have already been removed at this point, this step is done directly with the 2D fraction.
Additional processing steps can be applied to achieve the desired quality in terms of chloride, metal or ash content for various applications (cement works: rotary kiln or calcinator, fluidized bed furnace). The granular size of the fuel will depend on the customer requirements. The plant design can also be adjusted to influence the caloric value of the RDF.
