Operation principle: starter motor, driven by motor axis of rotation, rotating shaft drives helical blade to rotate, slag is thrown in screen casing from the charging aperture of outer tube bottom, helical blade promotes slag and moves up along screen casing, slag is when moving up, slag can produce with the inwall of screen casing and rub, thus the less steel slag particle in slag is passed from the sieve aperture screen casing, less steel slag particle falls from the cavity between screen casing and outer tube, and discharge from the second discharging opening of outer tube bottom, larger steel slag particle can be stayed in screen casing, and the first discharging opening from outer tube top under the promotion of helical blade is discharged.
Compared with prior art, the advantage of this programme is: by coordinating of helical blade and screen casing, make slag when moving up, less steel slag particle is sized out, larger steel slag particle is discharged from first discharging opening at the top of outer tube, thus make slag be sized classification while movement, avoid less steel slag particle and repeatedly ground, thus improve the grinding efficiency of roller mill.
Further, thrust bearing is provided with between described rotating shaft and base plate.Rotating shaft is when driving helical blade rotate and promote slag, slag can produce downward power to helical blade, thus makes rotating shaft bear downward axial force, by arranging thrust bearing, be conducive to improving rotating shaft and bear larger axial force, thus improve the stability of structure.
Further, the bottom of described support is provided with roller.When moving lifting device, roller being set by the bottom at support, facilitating operative.
Further, described helical blade is provided with protruding block.When helical blade is when promoting slag and moving, by arranging protruding block on helical blade, thus adds the frictional force of helical blade and slag, thus slag is stirred, be conducive to slag and better sieve.
Further, described helical blade is provided with hard alloy abrasion-resistant layer.Be conducive to the anti-wear performance increasing helical blade, thus extend the service life of helical blade.
Further, support bar is provided with between described screen casing and outer tube.Enhance the attachment force between screen casing and outer tube, be conducive to the stability of the structure improving screen casing.
