<p>In a method of manufacturing sintered dolomite having raw densities exceeding about 3.0 grams per cubic centimeter in a shaft kiln from ground raw dolomite briquetted or pelletized into shaped bodies, the steps include deacidifying and heating the shaped bodies to a temperature of at least 1000 DEG C. in an upper region of the shaft kiln in a preheating and deacidifying zone heated with fuels of a low thermal content, thereafter sintering the shaped bodies in a lower sintering zone heated with fuels of high thermal content, so as to heat the shaped bodies to a temperature of about 1600 DEG C. to about 2000 DEG C., and subsequently passing the sintered bodies into a lower cooling zone, cooling the bodies therein, and, thereafter, discharging the sintered bodies from the shaft kiln.</p> |
