Cement Manufacturing Process - The Engineering Community

Aug 28, 2018· Cement Manufacturing Process. Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.

Re: Raw meal to clinker ratio - Page 2 of 5

For a kiln system where all dust streams are returned directly to the kiln, the final formula would be;-(1 - A/100) / (1 - R/100) Where;-A = coal ash absorbed into clinker (expressed as a percentage). and. R = raw meal LOI (expressed as a percentage). A is calculated by;- A = (Tonnes coal fired * % ash of coal fired) / (tonnes of clinker produced)

Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill
