The invention relates to metallurgy, in particular to the design of the drum mill unloader. A drum mill unloader comprises a pin with a grate and with elevators in-series located behind it and a cap with spirals, wherein the elevators are installed in pairs, and each previous elevator of the pair is perforated. The invention provides increased intra-drum circulation of material, increase of its degree of grinding, reducing the amount of effort on the working surface, eliminating the need for external circulation (spiral classifier) of the material and loading elevators, simplification of the production line, reducing costs and improving quality of the ground product. |
