How Cement Is Made

The finely ground raw material or the slurry is fed into the higher end. At the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. As the material moves through the kiln, certain elements are driven off in the form of gases.

Alternative Fuels in Cement Manufacture

• The use of alternative fuels in cement kilns maximises the recovery of energy from waste. All the energy is used directly in the kiln for clinker production. It also maximises the recovery of the non-combustible part of the waste and eliminates the need for disposal of slag or ash, as the inorganic part substitutes raw material in the cement.
