Cement industry and its cement production is under continuous economic and ecological pressure. Reducing fuel cost and cutting the carbon dioxide emissions are the top requirements. For both an increased use of AFR – alternative fuels and raw materials – is a good answer.
The controlled usage of AFR has no negative effect on the basic emission of the plant, nor on the clinker burning process nor on the product quality. It is no longer utilizing a portion of cheap fuel or waste disposal, it is a well-designed systematic co-processing of AFR. Using the full potential of AFR Co-processing four major steps have to be considered:
• Assess and analyze available wastes, residues or biomass and the existing clinker production plant to find fuels fitting to the raw material and burning situation.
• Engineer or use the right treatment of wastes and residues to produce tailor-made fuels fitting the raw material and burning situation of the plant.
• Get suitable transport, storage and dosing equipment fitting to the envisaged burning or feeding point at the clinker production plant.
• Get the clinker production plant equipped or adapted with suitable burner, appropriate calciner and process design.
Following the FuelTrack, a maximum of the energy content in the AFR can be utilized in the clinker production process and the ash minerals can be integrated into the clinker.
According to the four steps, before choosing and preparing alternative materials it is important to analyze and assess the materials for their suitability in the clinker burning process with regard to chemistry, emission and environmental impact as well as its potential behavior in the burning process. The sustainable, ecologic and economic availability has to be analyzed and evaluated.

Residues, wastes and biomass in nearly undefined size and form are typically either separated or jointly pre-processed to remove minerals and organics, metals, glass, ash or other harmful constituents from the fuel. After shredding, sieving, screening and/or separation we receive Highly enriched Caloric Fraction (HCF) with a defined lump size of less than 300 mm.
AFR/RDF Treatment is varying and depending on many circumstances because the incoming material is anything but homogeny over the time of processing. To face all of the possible influences that are challenging the treatment process we use all of our experience to prepare the best available solution to match the requirements for the final fuel that is requested by the cement plant or other off-takers.
Possible steps are sorting, shredding, screening, separation and finalizing. In most cases the installations are tailor-made because of different pre-conditions but the general steps remain the same.
Within the RDF treating step final engineered fuel is produced. To process well-defined RDF / SRF the pre-processed HCF needs a second shredding step which is done by qualified fine-shredders. The finalized fuel can be used directly, stored or transported to the final destination.
We appreciate to support you with a wide range of wear parts to keep your machines in good condition also after a long time of operation. For more information and specified requests please feel free to contact us.

Handling and Dosing
Processed fuel not going direct from the processing plant to the consumer in the cement plant may need truck transport and subsequently truck unloading at the plant level. The shown Truck Unloading Station (TULS) has the special feature of working nearly dust- and spillage-free without the need of a de-dusting system. Unloading capacities up to 350m³/h are possible. It can handle moving-floor as well as tipping truck trailers. Other TULS designs in single or double trailer reception are also available depending on the local circumstances.
Within the RDF/SRF handling the material should be conveyed mainly by mechanical means: Short and low-incline transport at the processing plant can be handled with standard flat belt conveyors.
For handling in the cement plant and for higher inclination completely closed drag chain conveyors are the best choice. Short connections can be realized by screw conveyors. For long distances of RDF transport chain conveyors reach limits. Therefore we offer suitable dust-free alternatives like tube conveyors to bridge high distances.
The AFR process is specially designed to generate a consistently high quality alternative fuel for Cement Kiln use and this production system is designed with flexibility to enable variable feed-stock materials to be added and blended to produce this high quality AFR product as the end result. The system allows the process to be optimised to suit variation in feed stock materials.
