Abstract:
A vertical roller mill includes a housing, a chute that supplies materials to be grinded to a center portion of the housing, a grinder that is provided below the chute and grinds the materials to be grinded, an exhaust pipe that is provided above the grinder, a transport mechanism that forms an air flow for transporting, to the exhaust pipe, grinded materials grinded by the grinder, and a flow-constricting flow path provided between the grinder and the exhaust pipe and narrows a flow path area for the air flow, in which the flow-constricting flow path is formed between a first flow-constricting ring provided in the center portion of the housing and a second flow-constricting ring provided to protrude from the housing toward the center portion of the housing.
