Abstract
The invention relates to a device and a method for blowing out metal fractions from a stream of bulk material that is conveyed by bulk material means. The device comprises blow-out nozzles which are located on a drop section, and which are arranged along a width-wise extension of the stream of bulk material, for blowing against individual particles of bulk material in order to modify the trajectory in such a way as to produce a second sub-stream that branches off. The blow-out nozzles can be controlled according to the sensor coil scanning results relating to the bulk material particles. A plurality of sensor coils is provided underneath an essentially horizontal section of the stream of bulk material in the form of an LC oscillating circuit. Said sensor coils are provided for detecting the eddy currents that are induced. Optoelectronic means are also provided for determining the blow-out position and for determining the location of each of the particles of bulk material.
