Description
Technical Field
The utility model relates to a metallurgical equipment technical field, concretely relates to steel fragment sorting unit.
Background
Magnetic separators are known for separating iron metal from ore fines, one of which is known under the name "permanent magnet belt separator" as published in chinese patent No. 2269904. The magnetic separator comprises an ore feeding conveying part and a magnetic separation part, wherein the ore feeding conveying part and the magnetic separation part are arranged on the same rack, the magnetic separation conveying belt is positioned above the ore feeding conveying belt and is parallel to the ore feeding conveying belt, a magnetic system polar plate is arranged above the magnetic separation conveying belt, the magnetic poles in the magnetic polar plate are alternately arranged along the movement direction of the magnetic separation conveying belt and are consistent along the width direction of the conveying belt, so that magnetic mineral materials are automatically turned at high speed under the action of the multiple magnetic polar plates, and non-magnetic mineral materials clamped between the agglomerated magnetic mineral materials and the surface of the magnetic separation conveying belt are removed. Compared with the existing magnetic separator, the permanent magnetic belt type magnetic separator has a simpler structure and can separate the metal surrounded by the magnetic agglomeration. However, this kind of magnetic separator is only suitable for ore powder with the same or similar volume, such as steel blocks, and the separation effect is not very good because of the metal and non-metal blocks and powder with large volume difference in these materials.
Another source for steel or iron raw materials is the crushing of large volumes of iron or steel blocks that have been formed, which blocks are crushed during the crushing process, usually by means of manual or special crushers, and since there is no requirement or no restriction on the size of the crushed iron or steel blocks, and no special crushing is possible, the crushed pieces are of different sizes and are contaminated with impurities that, if directly fed into the furnace, affect the quality of the final product.
