PURPOSE: A stack for dust collection and a dust collector for a finishing mill with the same are provided to prevent air pollution by rotating the air discharged through the stack so that foreign materials and moisture included in the air get together and drop. CONSTITUTION: A stack for dust collection comprises a body(24), a guide unit(30), a lower case(26), and a transfer pipe(28). The body forms a discharge path(22) with wide bottom and narrow top through which the transferred air flows outside. The guide unit is spirally projected in the body to guide the flow of air passing through the discharge path. The lower case stores dropped foreign materials. The transfer pipe delivers collected foreign materials.
