Background
The ball mill is the mainstream equipment for mineral separation and grinding at present, and the consumption of grinding medium steel balls is 1.5 hundred million tons per year in a global range. The ball diameter of the steel ball is continuously reduced in the abrasion process, and when the steel ball reaches a certain ball diameter, the steel ball flows out along with ore pulp and is discharged out of the ball mill through the stranding cage. For the overflow ball mill, due to the reverse spiral in the stranding cage at the ore discharging end, the steel balls discharged along with ore pulp return to the ball mill again, and the discharge amount of the steel balls is small. For the lattice type ball mill, because the existence of the reverse spiral is not existed, the diameter of the steel ball is discharged out of the mill, the discharge amount of the steel ball is large, and particularly, when abnormal ball discharging occurs after the grid plate at the ore discharging end is damaged, the ball discharging amount is particularly huge, which is often occurred in the production practice.

Most ore dressing plants adopt manual waste ball picking, the method is time-consuming and labor-consuming and low in efficiency, some ore dressing plants are provided with a screen at a ball-milling ore discharging end, steel balls on the screen return to the ball mill, and the ball mill is distributed, so that the method has poor effect and cannot effectively recover the steel balls. In summary, the problems in the prior art are as follows: the steel balls discharged by the ball mill are directly treated as scrap steel, the recyclable steel balls are not recycled, the resource waste is caused, the consumption of the steel balls is large, and the cost is high; the contact area of the magnetic lining plate with the steel balls and the ores is large, the abrasion is serious, the service life of the lining plate is short, and the cost is high; and the mode of manually picking up the waste steel balls is carried out on the recovery of the waste steel balls in part of concentrating mills, so that the manual labor amount is large. Therefore, a new solution to solve the above technical problems is urgently needed.
