Abstract
In a rotary classifier and a vertical mill, a rotary separator (33) is configured such that plural rotary blades (43) are fixed to an outer circumference portion at predetermined intervals in a circumferential direction between an upper support frame (41) and a lower support frame (42), which have a disk-like shape, wherein a tilted surface (52), which tilts at an acute angle relative to a tangent line (T) to a rotation locus (G1) on an outer circumference side and includes a concave portion (51) formed between an outer end (43a) and an inner end (43b), is formed on a front surface of each of the rotary blades (43) in a rotating direction.
