Method and device for crushing and drying moisture-containing material, especially wood

摘要

A method for crushing and drying damp wood, wherein the wood is introduced into an impact reactor, which has a substantially cylindrical main body, in the closed interior space of which there rotates a rotor with at least one impact element, which contacts the wood and crushes it into part-constituents while generating a great transfer of momentum. The interior space of the cylindrical main body is assigned a suction removal device, which during the impact crushing removes the mist of moisture produced when the impact element makes contact with the material, and the interior space of the cylindrical main body has admitted to it hot gas, heated by waste heat from a combustion process, at a temperature of less than 95° C., in particular less than 80° C., or the exhaust gas from a combustion process, which after a collision of the impact element with a material constituent penetrates the material constituent in place of the moisture leaving. Also a device for carrying out the method.

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.
