Abstract: A plant for the production of ore comprising a proportion of fines, additives and green agglomerates optionally containing a binder, provided with an outer coating consisting of a combustible containing fine-grained carbon, such as coke. In the plant, the ore is mixed with the additives and the optionally available binder. The mixture is pelletized and the green agglomerates thus formed are coated with the combustible, whereby the combustible is introduced into an agglomeration drum. In order to enable continual production of homogeneous-quality green agglomerates, the mixture is pelletized in the agglomeration drum and the combustible is added in an area of the longitudinal extension of the agglomeration drum where the size of the green agglomerates formed in the agglomeration drum is sufficient for further processing.

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.

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.

Abstract: A raw mixture for sintering, containing ore with a fines fraction, at least one addition, returned sintered material from a subsequent sintering process and optionally a binder produced by mixing followed by granulation. To achieve high throughput capacities while avoiding wear to installation parts and resultant operating failures, the returned sintered material is added after the ore has been mixed with the addition and with the optional binder.

Abstract: The technical problem of the invention is to create a process where the second layer is of higher sintering quality and improved waste gas values are achieved. The process according to the invention for the thermal transformation of materials containing organic substances in a two-layer sintering process, charges the second layer (8) containing the organic substances at a maximum layer thickness of 20% of the first layer after ignition of the first layer (1) and thermally treats the second layer when the combustion zone of the first layer ensures the combustion of the organic substances coming from the second layer and entering the combustion zone of the first layer, following the pressure difference, is least 70%. The area above the combustion zone of the first layer still must have a temperature preventing the organic substances coming from the second layer and entering the first layer from condensing.
