Abstract of the Disclosure The known roller mill associated with a rotary- type classifier is improved in a number of aspects. The improvements reside in that a downwardly convex flow- rectifying cone is disposed under the rotary type classi- fier and an upwardly convex slant plate for ejecting a sediment within the classifier is disposed above the flow- rectifying cone; that a baffle plate for hot air which covers a part of an upper side of a blow-up passageway of hot air provided along the outer circumferential portion of a turn table as spaced therefrom; or that the rotary classifier comprises a plurality of classifying blades disposed along generating lines of an inverse frusto-conical surface having a vertical axis and rotating about the axis to separate powder in a gas flow into fine powder and coarse powder, an angle formed between the classifying blade and a rotary radius is selected to be 30° to 60°, and an angle formed between the classifying blade and the rotary axis is selected to be 0° to 40°; either singly or in combination.
