The rotating rod (124) is rotatably arranged inside the ore selection box body (101). The rotation of the rotating rod (124) drives the sliding connecting shaft (122) on the other side to move up and down. The sliding connecting shaft (122) 22) By adapting the inner connection block (119) and the side guide block (120), as well as the lower limiting guide block (106) and the guide slot (107), the centrifugal separator (116) is driven to move up and down as a whole, helping the ore raw materials inside the centrifugal separator (116) to be screened evenly up and down, and then under the action of centrifugal force, ore raw materials of different sizes are screened out from the third ore selection port (115), the second ore selection port (114) and the first ore selection port (113) on the centrifugal separator (116), and then fall into the first material leakage port (22), the second material leakage port (23) and the third material leakage port (24) on the lower collecting box body (112) respectively, and then the telescopic rod (25) is driven to expand the sealing plate (26) on the telescopic rod (25), and the material is discharged from the lower classification discharge port (111); Step S2: while the liquid pump (110) is rotating, the internal liquid pipe nozzle (108) is connected to the hose (109) to spray liquid on the rotating centrifugal separator (116) to increase humidity; Step S3: The screened raw materials enter the bottom of the magnetic transmission belt (11) from the inner transmission belt (6), and then the rotation of the magnetic transmission belt (11) drives the magnetic materials in the screened raw ore to separate, and the non-magnetic raw ore slides from the side slide (7), and the magnetic materials pass through the magnetic transmission belt (11) into the upper air box (10) and slide from the rear slide (8), thereby distinguishing and screening the magnetic raw materials from the non-magnetic raw materials.
