Plastics, waste paper and textiles represent examples of waste products that are very combustible and have a high calorific value. These products, in shredded form, can be used as alternative energy sources for a number of processes, for example, in cement works. Shredding these products not only reduces the volume of waste, but also allows valuable fossil fuels such as coal, natural gas and oil to be partially substituted, thus saving energy. Special cutters for the MR and XR series have been developed for this area of application to ensure that high through-put rates can be achieved.
UNTHA Shredders’ XR series is particularly suitable for use as a coarse shredder in the production of energy from waste at substitute fuel production plants. Machines from this series can be universally used for shredding a range of materials, e.g. carpets, rolls and bales. The quick and easy, hydraulically controlled diversion of non-shreddable objects guarantees high availability, and the use of re-usable reversible cutting blades ensures that the shredding process is cost-effective.
Our MR series can produce the right granule size for blast injection into rotary furnaces in a single step. Small granule sizes are made possible through the use of perforated screens with hole diameters of 20 to 80 mm. Special hydraulically pre-tensioned units called stator bars prevent the cutters from breaking if foreign bodies are present.
The MR and XR series can be equipped with electro-mechanical, or electro- or diesel-hydraulic drives, according to your own requirements.
