  • Method and device for processing automobile tires
    Patent number: 6364225
    Abstract: Product pieces (2) produced from old tires are thermally processed in a discontinually operated device (1). The product pieces (2) consist of a material compound, which comprises at least one material component which decomposes by heating, by mechanically moving and/or fluidizing the product pieces (2) in the device (1) and by heating to an material decomposition temperature via heated contact surfaces of the device (1). At this temperature the material compound decomposes in one or several solid matter material components and fluids, which can be taken out of the device (1) separately. A single component separation is made possible by the method and the use of the device. Environmental impact is mostly avoided.
