摘要： The present invention relates to a mixing device comprising a preferably rotating container for holding a mixture, at least one mixing tool arranged inside the container, and a heating device for heating the mixture. In order to provide a mixing device of the type mentioned above which permits the fastest possible heating of the mixture, preferably also to temperatures above 200°C, it is proposed that the container be composed at least partially of an electrically conductive material and the heating device comprise at least one coil which can be excited by an alternating electric field and which is arranged in such a way that eddy currents are produced in the electrically conductive material of the container by the magnetic field change that arises when the current flow is changed.

摘要： The invention relates to a device (1) for reprocessing and cooling foundry sand, comprising a mixing container (2) and a mixing tool that can be rotated about a drive shaft (4), wherein an air feed (7) is provided for feeding air into the container interior. The problem addressed by the invention is that of providing an improved device by means of which a more uniform fluidized bed is achieved, preferably over the entire cross-section of the mixing container, wherein furthermore the proportion of the solid particles entrained by the gas flow should be reduced. This problem is solved, according to the invention, in that the mixing tool has at least two mixing vanes (8) spaced apart from each other in the vertical direction and at least one mixing vane has a mixing blade having a surface that is angled with respect to the horizontal.

摘要： It is known that poorly-flowing solid materials can lead to an inhomogeneous mass flow of the solid across the discharge cross-section of a silo. If the solid in the silo is also heated or cooled the uneven mass flow can lead, for example, to local variations in temperature and/or hence to varying product properties. According to the invention, the above problem may be resolved, whereby a method and a discharge device for a solids silo and a solids silo are disclosed, permitting a controllable solids discharge evenly across the cross-section of the silo. The cross-section of the silo discharge is divided into several, preferably equivalent, partial cross-sections to which a continuously controllable discharge device is connected. The solid flow discharged from the controllable discharge devices can be collected on a continuous conveyor arranged therebelow and removed. The even solid mass discharge from the continuous discharge devices is controlled, depending on measured signals from several equivalent sensors, recording the local mass flow in the corresponding partial sections of the silo, by means of the conveyor power of the discharge device, relating to each sensor. Where electrically-conducting solids are used which are to be heated in the silo using electrodes by means of resistance heating, the control of the discharge devices is achieved with the measured current at the electrodes.

摘要： The present invention relates to a granulating and/or agglomerating tool for a granulating and/or agglomerating device with a fastening shaft and a substantially disk-shaped element with a diameter d which is fastened thereto and has an upper surface, a lower surface and a circumferential surface connecting the upper and the lower surface. In order to provide a granulating and/or agglomerating tool for a granulating and/or agglomerating device and a corresponding granulating and/or agglomerating device and a method for granulating or agglomerating with which the desired granulating or agglomerating result can be obtained very much faster and above all with a significantly finer granulated material with a significantly higher yield in the range of from 0.1 to 0.8 mm, it is proposed according to the invention that the circumferential surface exhibits a plurality of essentially V-shaped grooves running parallel to the axis of the shaft.
