A model has been developed to describe the breakage behavior of particle breakage in a smooth double roll crusher. In addition to this, an empirical relationship has been obtained between Hardgrove Grindability Index (HGI) of material and breakage parameters. The model uses matrix method of breakage process analysis.
Empirical Rule Formula. For a normal distribution: 68% of data lies within 1 standard deviation of the mean. 95% of data lies within 2 standard deviations of the mean. 99.7% of data lies within 3 standard deviations of the mean. Empirical Rule Definition. The Empirical Rule, or 68-95-99.7 rule, describes the spread of data in a normal distribution.
