Abstract:
1. A method for processing various materials, the method comprising the steps of: providing an apparatus comprising a grinding section and a mixing section so that at least in the grinding section the apparatus comprises at least two annular feed gaps placed one within the other defining a first feed gap and a second feed gap, feeding at least two different materials into the feed gaps so that a non-melting material is fed into the first feed gap and a material that melts during processing is fed into the second feed gap, grinding the non-melting material in the first feed gap and, simultaneously during the grinding, dehydrating the non-melting material in the first feed gap, melting the material during processing in the second feed gap, mixing the ground material with the melted material in the mixing section of the apparatus after the grinding and the melting, and extruding the mixture of the materials into a product, wherein the non-melting material is ground and dehydrated in the same apparatus in which the materials are mixed.
