• ## Bogue calculation Understanding Cement

The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement Although the result is only approximate, the calculation is an extremely useful and widelyused calculation in the cement industry The calculation assumes that the four main clinker minerals are pure minerals with compositions:GRINDING MILL INVESTIGATION (METRIC SYSTEM OF UNITS) 1901 Mill Critical Speed 1902 Percent of Critical Speed 1903 Ratio: Free Height to Mill Diameter 1904 Internal Volume of Mill 1905 Percent Loading of Mill 1906 Bulk Volume of Ball Charge 1907 Weight of Ball Charge 1908 Weight of Feed in Mill 1909 Steel to Clinker RatioCement Manufacturer's HandbookA simple equation for calculating net power draft is P 200 3 cD 25 m LKl kW (812) Kl is the loading factor which can be obtained from Figures 85 for the popular mill types 3 c is the mill speed measured as a fraction of the critical speed More reliable models for the prediction of the power drawn by ball, semiautogenous and fully autogenous mills have been developed by Morrell and byTECHNICAL NOTES 8 GRINDING R P King

other industries (eg cement and mineral ore storage) very large silos are used and every silo must be individually designed for the special conditions It should be noted that each silo is normally designed to contain a very limited range of solids, and that the use of a silo designed for one kind of solid to store different solids can easily cause damage Bulk solids vary very much in their
