Title:
DRY SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2023/070894
Kind Code:
A1
Abstract:
A dry separator, comprising a forward air blowing path (1) and an eccentric magnetic rolling mechanism (2). The eccentric magnetic rolling mechanism (2) is partially arranged in the forward air blowing path (1); the forward air blowing path (1) is used for blowing forward air in the same direction as material conveying to the surface of the eccentric magnetic rolling mechanism (2); the eccentric magnetic rolling mechanism (2) is used for conveying materials, and is further used for providing an eccentric rotating magnetic field; a feeding area (4) is provided above the eccentric magnetic rolling mechanism (2); and a tailings treatment mechanism (5) and a concentrate area (6) are provided below the eccentric magnetic rolling mechanism (2). A multi-physical-field coupled complex separation environment is provided for dry magnetic separation of ultrafine crushed materials, and the materials are mainly subjected to the multi-force combined action of gravity, centrifugal force, magnetic overturning force, forward wind force, magnetic field suction force and the like, thereby achieving the purpose of graded, efficient and fine separation, and solving the problem that dry separation cannot be effectively performed on dry superfine powdery materials after dry grinding and grading.
