Document Type and Number:
Japanese Patent JP7317631
Kind Code:
B2
Abstract:
The present invention is to properly remove the pulverized fuel deposited inside a rotary classifier without increasing the manufacturing cost of a mill or the weight of the rotary classifier. According to the present invention, provided is a solid fuel grinding apparatus comprising: a rotary table (12) to which solid fuel is supplied from a fuel supply unit (17); a coal feeder for supplying the solid fuel to the fuel supply unit (17); a pulverizing roller (13) for pulverizing the solid fuel between the same and the rotary table (12); the rotary classifier (16) having a plurality of blades (16a) rotating about a central axis of rotation; and a control unit which controls the rotation of the rotary table (12), the supply of the solid fuel by the coal feeder, and the rotation of the rotary classifier (16). In the fuel discharge period from stopping the supply of the solid fuel by the coal feeder until stopping the rotation of the rotary table (12), the control unit controls the rotary classifier (16) to perform a speed increase operation to temporarily increase the number of revolutions per unit time.
