The steel slag is dried by a tumble dryer so that the water content of the steel slag is less than 1.5%. The dried steel slag is sent to the electromagnetic pre-magnet for pre-magnetization, and then sent to the homogenization reservoir for homogenization, storage, and then dry. For grinding, the granular steel of 3 mm or more and the steel slag powder of less than 3 mm are separated, and then the steel slag powder of 3 mm or less is selected by a powder separator for wind power separation, so that the steel slag powder is divided into more than 180 mesh and less than 180 mesh. Grade particles, the particles larger than 180 mesh are placed in a double-cylinder dry-type permanent magnetic separator for ferromagnetization . The magnetic slag powder is demagnetized by electromagnetic demagnetizer to reduce the specific susceptibility of the steel slag powder. The magnetic agglomeration is carried out, and the demagnetized steel slag powder is sent to a ball mill for fine grinding to below 180 mesh, and the steel slag iron fine powder and the steel slag fine powder are separated by a powder separator. The technical process has the advantages of low production process cost and no pollution to the environment. The utility model is characterized in that: steel slag containing about 30% iron content, particle size of 0-12 mm and water content of about 10% is dried by a tumble dryer, so that the water content of the steel slag is less than 1.5%, and the steel slag after drying is sent. The electromagnetic pre-magnetizer is pre-magnetized, and then sent to the homogenization reservoir for homogenization and storage, and then subjected to dry pre-grinding, and the granular steel of 3 mm or more and the steel slag powder of less than 3 mm are separated to obtain a granular steel product, and then The steel slag powder below 3 mm is selected by the powder separator for wind power separation, so that the steel slag powder is divided into two grades of particles larger than 180 mesh and less than 180 mesh, and the particles larger than 180 mesh are placed in the double cylinder dry permanent magnet magnetic separator for iron Magnetic separation, the separation of steel slag iron slag fine powder and steel slag powder is obtained, and the steel slag iron fine powder product is obtained. The magnetic slag powder is demagnetized by electromagnetic demagnetizer to reduce the specific susceptibility of the steel slag powder and cancel the magnetic agglomeration. Then, the demagnetized steel slag powder is sent to a ball mill for fine grinding to below 180 mesh, and the steel slag iron powder and the steel slag powder are separated by a powder separator to obtain a steel slag iron powder and a steel slag powder product.
