Rotary superfine slag powder screening device

The utility model provides a rotary type superfine slag powder screening device, which relates to the technical field of screening devices, and comprises a screening mechanism, the bottom of the screening mechanism is fixedly connected with a collecting mechanism, the screening mechanism comprises two supporting plates, the tops of the two supporting plates are fixedly provided with three groups of fixing blocks, and the outer surface walls of the six groups of fixing blocks are provided with round holes. And bearings are fixedly inserted into the inner surface walls of the six groups of circular holes. When the device is used, under the action of the screening mechanism, the motor serves as driving force, under the cooperation of the first screening barrel and the second screening barrel, superfine slag powder makes full contact with the inner surface walls of the screening barrels, screening treatment on the superfine slag powder is achieved, screening holes of the first screening barrel are different from
