Title:
SOLID FUEL CRUSHING APPARATUS, AND CONTROL METHOD FOR SOLID FUEL CRUSHING APPARATUS
Document Type and Number:
Japanese Patent JP2023107454
Kind Code:
A
Abstract:
To suppress a rapid increase of a carrying-out amount of fine powder fuel from a solid fuel crushing apparatus, and a rapid decrease of thickness of a layer of the solid fuel existing on a crushing table, when supply of the solid fuel is started.SOLUTION: A solid fuel crushing apparatus includes a crushing table 12, a mill motor 15, a crushing roller 13, a rotary type classifier 16, a lift detection sensor 43a or a drive current detection sensor 15a for detecting a biting state where solid fuel is bitten between the crushing table 12 and the crushing roller 13, and an inverter control part for controlling the rotation speed of the crushing table 12 driven by the mill motor 15, wherein when supply of the solid fuel to the crushing table 12 from a coal supply pipe 17 is started, the inverter control part controls the rotation speed of the crushing table 12 that the rotation speed is lowered to second rotation speed from first rotation speed according to detection of the biting state.SELECTED DRAWING: Figure 2
