Abstract
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.
