Description

Technical Field

[0001] The present invention relates to the field of mechanical processing technology, and in particular to an automated material powder screening device and method. Background Art

[0002] In metal smelting processing, there are many powdered materials that need to be screened to remove impurities. During the screening process, natural ore (iron ore), an important raw material for iron production enterprises, is gradually selected to remove iron through crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. Iron ore is an aggregate of minerals containing elemental iron or iron compounds that can be economically utilized.

The said unloading concave plate 12 is movably inserted on the inner side of the said flip opening through the said unloading shaft 13. The said several filter screens 14 are respectively installed on the inner side of the said several circular inner vibration blocks 4. The inner side of the said vibration screening box 3 is provided with a number of lifting sealing openings. The said lifting baffles 15 are respectively movably inserted on the inner side of the said lifting sealing openings.
