In a method and a device for pulverizing bulk material containing plastic, whose grain is highly flexible and whose loose bulk is highly compressible and which is initially provided in a coarse grain, is subsequently heated and compressed and is then converted into a finer grain, the bulk material at least partially contains thermoplastics. Before and/or during and/or after the compression, the bulk material is at least partially melted in such a way that it is provided in the form of an endless strand or slab after the compression and heating, which is cooled and converted into the finer grain in a coherent state using a cutting tool, the thickness of the strand or the slab being between 5.0 mm and 100 mm, preferably between 10 mm and 50 mm, the bulk material in the fine grain having a grain size in the range from 0.0 mm to 20 mm, preferably from 0.0 mm to 5.0 mm, more preferably from 0.0 mm to 2.0 mm.
A method for pulverizing bulk material containing plastic, whose grain is highly flexible and whose loose bulk is highly compressible and which is initially provided in a coarse grain, is subsequently heated and compressed, and then converted into a finer grain, wherein the bulk material, which at least partially contains thermoplastics, is at least partially melted before and/or during and/or after the compression in such a way that it is provided in the form of an endless strand or a slab after the compression and heating, which is cooled and converted into the finer grain in a coherent state using a cutting tool, the thickness of the strand or the slab being between 5 mm and 100 mm, preferably between 10 mm and 50 mm, and the bulk material in the finer grain having a grain size in the range from 0.0 mm to 20 mm, preferably from 0.0 mm to 5.0 mm, more preferably from 0.0 to 2.0 mm.
A device (1, 31) for pulverizing bulk material containing plastic, whose grain is highly flexible and whose loose bulk is highly compressible, and which is initially provided in a coarse grain, the device having a heating unit (2) for heating the bulk material, a compression unit (3) for compressing the bulk material, and a pulverizing unit (6) for converting the bulk material into a finer grain, wherein the bulk material, which at least partially contains thermoplastics, may be at least partially melted using a heating unit (2) before and/or during and/or after the compression in such a way that it is provided after the compression and heating in the form of an endless strand or a slab, and an endless strand or a slab of the bulk material is producible using the compression unit (3), the thickness of the strand or the slab being between 5 mm and 100 mm, preferably between 10 mm and 50 mm, and a bulk material being producible using the pulverizing unit (6) from the strand or slab in the cooled state having a finer grain size which is between 0.0 mm and 20 mm, preferably between 0.0 mm and 5.0 mm, more preferably from 0 to 2.0 mm.
