Since the presence of iron affects subsequent processes, it is necessary to remove iron from the steelmaking vanadium slag. However, it is difficult to completely remove iron from the vanadium slag before the vanadium slag is finely ground. In order to obtain finely ground vanadium slag, it is common practice to grind the steel-making vanadium slag using a ball mill. The ball mill can be divided into a dry type and a wet type, and mainly comprises a feeding hole, a discharging part, a rotary part, a transmission part and the like.
