Ball and rod mixing mill for steel slag materials

The utility model discloses a ball and rod mixing mill for steel slag materials, which is used for solving the problems of low yield and high consumption caused by the fact that steel balls are wrapped by steel slag when the steel slag with water content of about 5% is milled by a ball mill. According to the improvement, on the basis of a horizontal mill, a double-partition-bin assembly is arranged in an inner cavity of a roller and divides the inner cavity of the roller into a bar material grinding bin and a ball material grinding bin, the bar material grinding bin is located at one end of a feeding port, the ball material grinding bin is located at one end of a discharging port, and steel bars are put into the bar material grinding bin; and steel balls are put into the ball material grinding bin. The inner space is divided into two parts, and the steel bar is put into the front sub-cavity to replace an original steel ball, so that the problem that materials with high water content are adhered to the steel b
