摘要： A method of operating a crushing system including a vertical crusher that crushes crush raw meal, a crushed material circulating passage through which crushed material moves from a discharge port of the crusher to a supply port of the crusher, a classifier that is disposed at the crushed material circulating passage and classifies the crushed material into refined powder as a product and coarse powder to be returned to the crusher, a collector that recovers the refined powder, an extraction passage connected to an upper portion of the crusher, an extraction fan that extracts a gas from the crusher to the extraction passage at a set extraction flow rate, and a dust collector that separates fine powder from the gas extracted from the crusher and supplies the fine powder to the crushed material circulating passage includes: acquiring a correlation between an extraction flow rate of the gas extracted from the crusher and fineness of the refined powder to be recovered; based on the correlation, estimating an extraction flow rate at which desired fineness is obtained; and setting the extraction flow rate as the set extraction flow rate.

摘要： A vertical roller mill (1) includes a housing (2), a chute (3) that supplies materials to be grinded to a center portion of the housing (2), a grinder (4) that is provided below the chute (3) and grinds the materials to be grinded, an exhaust pipe (9) that is provided above the grinder (4), a transport mechanism (6) that forms an air flow for transporting, to the exhaust pipe (9), grinded materials grinded by the grinder (4), and a flow-constricting flow path (10) provided between the grinder (4) and the exhaust pipe (9) and narrows a flow path area for the air flow, in which the flow-constricting flow path (10) is formed between a first flow-constricting ring (20) provided in the center portion of the housing (2) and a second flow-constricting ring (30) provided to protrude from the housing (2) toward the center portion of the housing (2).

摘要： A system (12) for monitoring the health of one or more bearings (14, 16) of a journal assembly (18) is provided. The system (12) includes a split spacer (46), one or more vibration sensors (48, 50), a speed sensor (52), and a controller (34). The split spacer (46) is configured to be disposed on a shaft (54) of the journal assembly (18), the shaft (54) is configured to support the bearings (14, 16). The vibration sensors (48, 50) are configured to detect vibrations emitted by the bearings (14, 16). The speed sensor (52) is configured to measure the rotational speed of the bearings (14, 16). The controller (34) is configured to electronically communicate with the vibration sensors (48, 50) and the speed sensor (52) and calculate a health status of the bearings (14, 16). The split spacer (46) includes two portions (56, 58) that define a cavity (60) configured to abut the shaft (54) so as to allow the vibration sensors (48, 50) to be disposed inside the split spacer (46) and next to the one or more bearings (14, 16).

摘要： This vertical roller mill is provided with: a rotary table having a grinding surface; a grinding roller (3) for biting and grinding a material between the grinding surface and the same; and a scraper (13) for adjusting a layer thickness of the material supplied to the grinding roller (3). The scraper (13) has: a scraper body (15) separately arranged above the grinding surface of the rotary table; a mobilizing means (16) for allowing the scraper body (15) to move in a direction away from the grinding surface; and a resistance adding means (17) for adding a resistance force to the movement of the scraper body (15) in the direction away from the grinding surface. Even when the layer thickness of the material supplied onto the grinding surface of the rotary table fluctuates, a height position of the scraper is automatically adjusted according to the fluctuation in layer thickness.
