  • Patent number: 10155996
    Abstract: A method and a device for producing granulates (1) which are obtained by the method steps: intensively mixing raw materials (2) and optionally additives (6) by adding water (3) to form a mixture (4); introducing the mixture (4) and optional additives (6) into a granulator (11); granulating the mixture (4) by adding water (3) to form raw granulates (12); introducing the raw granulates (12), water (3) and optional additives (6) into a rolling drum (17) and rolling the raw granulates (12) to form the granulates (1).
    Type: Grant

  • Patent number: 7914731
    Abstract: A process for sintering metal-containing materials, such as iron ores or manganese ores, on a sintering machine including a sintering belt for transporting the sinter mix during sintering thereof. The sintering belt has first, second and third portions. Sintering waste gas from the third portion is transported to and unified with sintering waste gas from the first portion in a mixing region to form a mixed gas, wherein the transporting distance of the sintering waste gas from the third portion to the mixing region is greater than the transporting distance of the sintering waste gas from the first portion to the mixing region. An apparatus for carrying out the process is disclosed, including the sintering belt, suction boxes operative at the portions of the belt, and lines for conveying the gas produced and the gases used in the process.

  • Patent number: 7811086
    Abstract: The invention relates to a feeding device for a belt-type sintering machine, with a feeding container for receiving the material to be sintered, with a conveying device for filling the feeding container with material to be sintered, with a feeding drum and a drum chute for feeding the material to be sintered onto the sintering belt. The feeding container has two discharge openings, one of which is connected to a feeding drum and one of which is connected to a feeding chute.
