METHOD AND DEVICE FOR GRINDING SOLID MATERIALS HAVING ADJUSTABLE DISCHARGING PARTICLE SIZE
Document Type and Number:
WIPO Patent Application WO/2022/016472
Kind Code:
A1
Abstract:
A method and device for grinding solid materials having adjustable discharging particle size, the device comprising a grinding disc housing (4); a movable grinding disc (5) and a static grinding disc (3) are placed in a grinding disc cavity (16) within the grinding disc housing (4) by using a structure in which the movable and static grinding discs are coaxial and have oppositely disposed grinding surfaces; the movable grinding disc (5) is driven by a driving mechanism such that same rotates within the grinding disc housing (4) so as to grind materials between the movable grinding disc (5) and the static grinding disc (3); the movable grinding disc (5) is further connected to a pushing mechanism, and the spacing between the movable grinding disc (5) and the static grinding disc (3) is adjusted by the pushing mechanism by means of pushing and pulling; and a top part rectifying air blower (17) and a side edge rectifying air blower (104) respectively blow air from above and a side of the movable grinding disc (5) and static grinding disc (3), and a central rectifying air blower (2) blows air towards the center of the static grinding disc (3). The grinding method and device are applicable to the crushing process of solid minerals. By using the clearance fit between the movable and static grinding discs, and collision of metal in a grinding process is avoided, which improves energy utilization efficiency; in addition, heating in a grinding process is reduced, ensuring the stability of mineral particle properties; and the accuracy of product particle size is ensured by accurately controlling the grinding clearance.
