摘要： The invention relates to a method comprising the followings steps: triturating and mixing raw materials, including calcareous clays, non-calcareous clays, feldspar, quartz, kaolin, calcite and dolomite; adding hydrated and unhydrated calcines which can be any or a combination of calcined dolomite, hydrated calcined dolomite, sintered dolomite, quicklime, calcium hydroxide, sintered lime, or a mixture thereof, and which may also include calcite or dolomite; granulating with a quantity of water of between 1 and 20%; and obtaining the optimum moisture content by means of drying, for the subsequent pressing of the solid granule under optimum conditions. The method according to the invention reduces the consumption of water during the process of mixing the raw materials by grinding, and reduces the consumption of energy used in the drying of the granules and the firing cycles, as well as reducing CO2 emissions into the atmosphere
