A second discharge hopper 22 is set at the top of the inner side of the rolling ring 4. The second discharge hopper 22 is used to receive the iron balls output by the transfer box 41. The water pipe 6 is set directly above the rolling ring 4. The water pipe 6 is used to spray water to the transfer box 41 to form ore slurry.
