Abstract

See full text

A pulverizing device includes: a housing; a pulverization table configured to rotate inside the housing; and a throat, disposed inside the housing on a radially outer side of the pulverization table, for forming an upward air flow. The throat includes: an inner ring extending along an outer periphery of the pulverization table; an outer ring, disposed on a radially outer side of the inner ring so as to form an annular flow passage between the inner ring and the outer ring; and a plurality of throat vanes disposed between the inner ring and the outer ring. The following expressions are satisfied: 2.0≤L/d≤4.0; and 0.5≤H/d≤1.5, where H is a gap between the inner ring and the outer ring with respect to a radial direction, L is a length of the throat vanes, and ‘d’ is a distance between adjacent two of the throat vanes.
