    • A pulverizing apparatus comprising a grinding chamber (5) formed between the inlet (11) of materials and the outlet (10) of the materials with bearings at the bottom (12), a shaft (2) supported in the bearings extending into the grinding chamber (5) and being driven by a motor (1), a conical plate (3) mounted at its apex on the shaft (2) with more than one radial blades or radial hammer plates (4) on its inner surface, a powder selector (6), an airblower (7) and an air duct (8) connecting the blower (7) with the grinding chamber (5). The air vent of said air duct (8) is located above the conical plate (3). The pulverizing apparatus merges hammer pulverization, impact pulverization and power self-grind into a whole, simultaneously finishes intermediate crush, fine crush and grinding materials, can improve the fineness, and transmits the unfinished product into a selecting system by using the high speed vortex.

    • Raw coal (1) is caused to fall through a coal feed pipe (2) on a table (3) and pulverized by a roll, fine coal particles (5) and coarse coal particles (6) resulting from pulverization are moved upward between an auxiliary classifier cone (7) and a mill casing (19) by means of hot air (4) supplied from below the mill casing (19), the hot air (upward stream) carrying fine coal particles (5) and coarse coal particles (6) moves across a space of triangular cross section formed between the inverted conical body of the auxiliary classifier cone (7) and the mill casing (19) and flows through blowoff openings (8) defined between deflector plates (9) so that it is changed to a lateral rotative stream toward a rotary classifier (11), upon impinging on downward-inclined rotating vanes (10) of the rotary classifier (11), coarse coal particles (6) are sprung back toward a lower portion of the auxiliary classifier cone (7) and separated from fine coal particles (5), and fine coal particles (5) separated from coarse coal particles (6) are ejected together with the upward stream through a pulverized-coal eject pipe (12) out of the roller mill. Coarse coal particles (6) sprung back toward the lower portion of the auxiliary classifier cone (7) move along the inner surface of the auxiliary classifier cone (7) and fall on the table (3) so that they are re-pulverized by the roll.
