Abstract
The invention discloses a castable screening machine. The machine comprises a crushing machine and a screening device. The screening device comprises a screening box, an upper screening plate and a lower screening plate. A first screen aperture and a second screen aperture are formed on the upper screening plate. A second screen aperture is formed on the lower screening plate. The inclining direction of the lower screening plate is opposite to that of the upper screening plate. The upper end of the lower screening plate is in contact with the boundary of the first and second screen apertures on the upper screening plate. The screening box is equipped with a large particle discharge tube, a medium particle discharge tube and a small particle discharge tube. A first conveyor belt, an elevator and a second conveyor belt are arranged between the crushing machine and the screening device. The medium particle discharge tube is connected with a medium particle gathering barrel. The small particle discharge tube is connected with a small particle gathering barrel. Bulk materials are crushed into particle materials by the crushing machine, and then screened into materials of large, medium and small diameter ranges by the screening device, in which the particle materials of the large diameter range are returned back to the crushing machine for re-crushing, and restaged by the screening device till the particle materials are completely graded into particle materials of the medium and small diameter ranges.
