Dry and wet ball mills have the same basic components, but there are some structural differences: 3 Discharging part Discharging port: Dry ball mill: The ball mill needs to be equipped with an air induction device, a dust exhaust pipe and a dust collector. The structure is more complicated, and the discharge port is straight.Web
