A crushing roller, 5 a crushing section, 6 a blower section, 7 a classifier vane (classifier), 8 a classification hopper, 12 an angle (rod-shaped member), and 13 an inertial separator.

Claims

[Scope of utility model registration request]

A coal supply pipe inserted into the casing from the upper part of the casing, a rotary table provided at the lower part of the casing for receiving the coal introduced from the coal supply pipe, and a plurality of rotary tables rotating in contact with the rotary table. a coal crushing section consisting of a crushing roller; a blowing section provided near the crushing section and supplying hot air that causes the crushed coal crushed in the crushing section to rise along the inner circumferential surface of the casing; and the casing. and a classification hopper having a classifier for classifying the pulverized coal raised by the hot air from the blowing section. A vertical mill characterized by being equipped with an inertial separator for coarsely classifying pulverized coal by assembling rod-shaped members in a staggered manner.
