Ball Mill Design/Power Calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed.

Chapter 8 Design of Concrete Mixes

cement content of about 300 kg/m3 cured in water at 20°C Such a mix made with Portland cement class 425 has a 7-day strength about 70% of that attained at 28 days • Richer mixes initially gain strength more rapidly so that 7-day strength may well exceed 75% of the 28-day strength Total 60 Chapter 5 Concrete Mix Design Calculations 11.

Bogue calculation

The Bogue calculation is used to calculate the approximate proportions of the four main minerals in Portland cement clinker 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 widely-used.
