Dry mills and wet mills, which one is more suitable for …
The fineness of limestone fine powder processed by the industrial dry mill is used. It can be up to 3000 mesh. Although it can't compare with the fineness of the wet mill, it is more than enough for the production of desulfurized lime. The fineness can be adjusted from 300-3000 mesh, which is enough to meet the needs of most enterprises.
