Abstract (en)
[origin: EP3995216A1] 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.
