Abstract: A cooling device (2; 50) for cooling bulk goods (4), which has a cooling shaft (8) and at least one supply chute (14) for introducing the bulk goods (4) into the cooling shaft (8). To achieve uniform cooling of the bulk goods (4), the supply chute (14) has a first wall (30) and a second wall (32) arranged opposite the first wall (30). At least part of the first wall (30) is arranged at a different angle of inclination (34) with respect to a vertical line (36) than the second wall (32).

Abstract: Disclosed is a composite system that includes a reduction system for reducing oxides in a continuous process, a process assembly for manufacturing liquid metal in a discontinuous process, wherein a reduction product is fed from the reduction system to the process assembly, at least one buffer device for receiving the reduction product and further starting materials and also for charging the process assembly, and a conveyor system for transporting the reduction product from the reduction system into the at least one buffer device.

Abstract: A conveying system comprising elements for conveying lumpy, particularly hot, conveying stock and a cover for shielding the conveying stock. Disclosed are measures for inerting the conveying stock. A combined system encompasses a reduction plant for reducing oxides in a continuous process and processing unit for producing liquid metal in a discontinuous process. The reduction product is deliverable from the reduction plant to the processing unit. A method for coupling a reduction method used for reducing oxides in a continuous process and a method used for producing liquid metal in a discontinuous process. A reduction product from the reduction method is fed to the liquid metal production method for processing.

Abstract: An apparatus for treating fine ore in which fine ore is dried by aid of a hot drying gas flowing around the ore particles. After having flown around the ore particles, the drying gas is purified while releasing entrained dust ore particles. The dust ore particles are collected and admixed to the dried fine ore. In order to avoid process disturbances in the further processing of fine ore due to excessive portions of dust ore particles present without the fine ore, drying is effected in the whirl-bed method under simultaneous wind-screening of the fine ore. The drying gas is passed through the fine ore under formation of a whirl bed and the speed of the drying gas is fixed at a rate at which entraining of dust ore particles having dimensions below a predetermined dimension is effected. The dust ore particles entrained in the drying gas are separated, collected and admixed to the dried fine ore in dosed amounts. The apparatus includes a fine ore whirl-bed drying means including a drying-gas feeding means.

Abstract: The device for drying coal comprises a plurality of damping vessels wherein the coal is pre-heated by means of steam and/or hot water, thereupon damped in a second stage, and finally pressure-released. The several damping vessels 1-17 are combined to form groups. Each of these groups is provided with a common group conduit 18 conveying live steam for damping, with a common group conduit 19 conveying wet steam from vessels for overflowing other vessels, and with a common group conduit 20 conveying hot water for rinsing. Over the damping vessels 1-17, there are provided distribution conduits which extend over all groups and which are conveying live steam 38, wet steam for overflowing 39, and hot water for rinsing 40. The group conduits 18,19,20 are connectable via valves 41,42,43 to the distribution conduits 38,39,40. Thus it is possible to include selectively into the procedure of any group any vessel of another group or the additional vessel 17 (FIG. 1).

Abstract: A discharge implement is provided, which is operable to discharge sponge iron from a shaft furnace and constitutes the bottom structure of the shaft furnace and is formed with flow passages for a cooling liquid. In order to ensure a uniform discharge, the discharge implement consists of a grate, which comprises parallel grate bars, which are non-circular in cross-section and are operable to perform rotational oscillations about their respective longitudinal axes. The grate bars are hollow so that they can conduct a cooling liquid, and they surround and are radially spaced from an inner tube, which has at least one opening, through which the interior of the inner tube communicates with the annular space defined between the inner tube and the shell of the grate bar.
