Cement kiln - Wikipedia

The kiln was restricted in size by the strength of the chunks of rawmix: if the charge in the kiln collapsed under its own weight, the kiln would be extinguished. For this reason, beehive kilns never made more than 30 tonnes of clinker per batch. A batch took one week to turn around: a day to fill the kiln, three days to burn off,.

addition of water in a ball or tube mill to produce a slurry typically containing 36% water. (range of 24-48%). Various degrees of wet processing exist, e.g. semi-wet (moisture content of 17-22%) to reduce the fuels consumption in the kiln. Clinker plants with wet kilns use more water per ton of cement than plants with dry kilns.
