6. The slag separation and recycling equipment according to claim 5, characterized in that, The specific steps of the recycling method for this slag separation and recycling equipment are as follows: S1. The slag to be processed is fed into the front feeding frame (107) through the feeding hopper (110). One of the crushing rollers is driven to rotate by an external drive source. The gears (104) at the end of the crushing roller mesh with each other, causing the other crushing roller to rotate in the opposite direction. Thus, the slag is initially crushed by the primary crushing section (101). The initially crushed slag passes through the screen hole (111) and falls into the screening cylinder (201). Some of the initially crushed slag passes through the connecting groove (114) and moves to the bottom of the middle covering cylinder (106). S2. The external drive source drives gear two (350) to rotate, which in turn drives the ring gear (340) and the ring slide rail (330) to rotate, which in turn drives the three sets of pushers (310) and the two sets of connecting rings (320) to rotate. The push plate (303) scrapes against the inner wall of the screening cylinder (201), pushing the initially crushed slag to move along the outer wall of the covering cylinder (106), and then through the feed inlet (109) and the discharge frame (107) into the crushing box (10) on the front side. 5) Inside, the slag is crushed again by the primary crushing section (101). At the same time, the push plate (303) pushes the slag that has been initially crushed below the middle covering cylinder (106) to move and pass through the feed inlet (109) and the discharge frame (107) into the middle crushing box (105). The slag that has been initially crushed is then crushed in the secondary crushing section (102). The slag after secondary crushing passes through the second screen hole (112) and falls into the screening cylinder (201). S3. The partially crushed slag and the secondary crushed slag pass through the connecting groove (114) and move backward to the bottom of the rear covering cylinder (106). They are pushed into the rear crushing box (105) by the push plate (303), crushed by the tertiary crushing section (103), and then fall into the screening cylinder (201) through the three sieve holes (113). S4. During the crushing of slag in the primary crushing section (101), secondary crushing section (102) and tertiary crushing section (103), the slag that falls into the screening cylinder (201) through the first screen hole (111), the second screen hole (112) and the third screen hole (113) is filtered through the fourth screen hole (203), so that the slag smaller than the aperture of the fourth screen hole (203) falls onto the first feeding hopper (501), and is washed downward by the three sets of nozzles (402), so that the slag follows the water flow through the fourth screen hole (203), and under the drive of the water flow, the slag moves to the right along the first feeding hopper (501); S5. Under the separation effect of the partition plate (505) and the partition plate (506), the slag moves with the water flow in the slag chute and is temporarily accumulated in the arc-shaped hopper (503). The turntable (601) and the permanent magnet plate (604) are driven to rotate clockwise by the external drive source. The fin plate (603) pushes the slag to the left and lifts the slag. The permanent magnet plate (604) then adsorbs the iron material in the slag and sprays water to the lower left side through the nozzle (702) to wash away the slag mixed between the iron materials. S6. The iron material follows the permanent magnet plate (604) to deflect to the right, and under the blocking effect of the scraper hopper (606), the iron material enters the scraper hopper (606) and moves along the scraper hopper (606) to the connecting hopper (607), and is finally transferred through the connecting hopper (607).
