And (3) opening the driving motor 12, driving the driving disc to rotate by the driving motor 12 through a driving belt, further driving the screening mechanism to rotate, and confirming the size of the screened slag.
When the required maximum size of slag is determined to be small, the differential motor 13 is turned on, the differential motor 13 directly drives the differential disc to synchronously rotate with the differential motor 13 on the driving wheel, at the moment, the initial speed of the rotating speed of the differential motor 13 is the same as the rotating speed of the driving motor 12, the position of the differential inner ring 21 on the inner screen is not changed, the distance between the differential inner ring 21 and the driving inner ring 23 is the same as the distance between the differential inner ring 21 and the driving inner ring 23 in the initial state, the inner screen is kept unchanged in the initial state, and the outer screen is kept unchanged in the initial state. Since the twisted strip 32 and the connecting rod 24 are not deformed, the mesh shape formed between the twisted strip 32 and the connecting rod 24 is the same as the initial state and is a parallelogram, and at this time, the mesh area is the smallest and the size of slag passing therethrough is also the smallest. And then the slag to be screened is poured into the feeding hole 19 and is guided into the screening mechanism through the material guide pipe for screening treatment.
When the required slag is confirmed to be large in maximum size, the differential motor 13 is turned on through the confirmed size, and the differential disk conducts differential processing on one end, connected with the screening mechanism, of the differential disk through the differential motor 13, so that the rotating speed of the differential inner ring 21 is smaller than that of the driving inner ring 23.
