[0002] Iron ore is an important raw material for iron and steel production enterprises. Natural ore (iron ore) is gradually selected for iron through processes such as crushing, grinding, magnetic separation, flotation, and gravity separation. Iron ore is a mineral aggregate containing elemental iron or iron compounds that can be economically utilized, and during the processing of iron ore, further grinding and powder making are required. There is a dry iron ore powder making device with the publication number CN219942997U. The rolling roller moves under the action of a motor through a cross bar to grind iron ore into powder. The externally connected air extractor generates negative pressure in the guiding plate through an air extraction pipe, so that the iron ore powder of conforming particles ground into powder passes through the mesh plate and is sucked out under negative pressure, so that powder can be sucked while grinding to improve the processing efficiency of iron ore. However, the mesh plate in this powder making device is easily blocked by iron ore powder during long-term use, which will affect the effect of sucking out iron ore powder under negative pressure, and thus greatly reduce the efficiency of iron ore powder making, bringing certain adverse effects to actual use. Therefore, improvement is needed. Content of the Utility Model
