Abstract
Cement is made by feeding to the kiln a mixture of slurry made by the wet method and powder made by the dry method, the mixture having a water-content of 10 to 35% by weight. The slurry and powder are fed to a mixer immediately before passing to the kiln, the feed of the powder being regulable in order to control the composition of the mix. Apparatus for carrying out the process comprises separate hoppers for the slurry and powder, the hoppers discharging into a mixer, in turn, discharges into the kiln, the feed of powder to the mixer being by means of a variable-speed screw conveyer.
