For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume. Density of Cement = 1440 kg/ m3 = 0.3636 X 1440 = 523 kg = 10.5 Approx. Bags.

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

Method for Estimating the Efficiency of Pulverizers. Grinding costs are an important item in cement manufacture, and the cost of power is one of the large items in grinding costs. Even where power is of secondary importance, cost items dependent on mill capacity are influenced by the efficiency with which the mill uses power.
Major compounds comprise about 90 % of the total cement compounds. Minor Compounds of Cement –. Though minor compounds are less in percentage in cement composition, they are still significant. Minor compounds in cement include- CaSO 4 .2H 2 O, MgO, TiO 2, Mn 2 O 3, K 2 O, Na 2 O, and alkalis.
The liquid percentage at 1450 0 C can be estimated using the formula. % Liquid content (1450 0C) = 3.0 x A+2.25 x F+S. Where A=Al 2 O, F=Fe 2 O 3, S= MgO+K 2 O+Na 2 O+SO 3 In Clinker. The normal range of liquid phase is 22-27%. Burnability is a reference value for raw meal indicating how difficult it is to burn.
