Abstract:
1. A method for crushing and drying moisture-containing material, the method comprising: introducing moisture-containing material into an impact reactor comprising a substantially cylindrical main body coupled to a suction device, a closed interior space of the cylindrical main body containing a rotor having at least one impact element; impact crushing the moisture-containing material by contacting the moisture-containing material with the at least one impact element and crushing the material into part-constituents while generating a great transfer of momentum; removing, during the impact crushing, a mist of moisture expelled from the moisture-containing material when the at least one impact element contacts the moisture-containing material with the suction device; and supplying the interior space of the cylindrical main body with hot gas having a temperature of less than 95° C., the hot gas being heated by at least one of waste heat from a combustion process, and exhaust gas from the combustion process, wherein the hot gas penetrates the part-constituents and replaces the mist of moisture removed by the suction device.
