CS230401B1 - Cement manufacturing method - Google Patents

Abstract

The invention relates to the manufacture of an active belite cement which behaves in the manner of Portland cement at a calcium rating of between 75 and 85, the heating and deacidifying process up to 950 DEG C being unimportant as far as the compressive strength of the cement is concerned, as is the heating process from 950 DEG C up to the sintering temperature which lies within the range between 1350 DEG C and 1450 DEG C. The clinker is subjected to mechanical activation, for example, in a ball mill, either subsequent to grinding in the ball mill or in place thereof, or the active condition of the belite is reached by the cooling process. Cooling is effected by quenching the clinker or tempering it or by gradual cooling, whereby the cooling gradient should be >500 cal/min in the temperature range between from 1350 DEG C to 1250 DEG C (upper limit) and from 1000 DEG C to 800 DEG C (lower limit).

Claims (5)

Object of the invention CLAIMS 1. A process for the production of cement, in particular belite cement from common raw materials, characterized in that the raw meal is treated with a lime saturation coefficient of 75-85 to heat without a designated heating mode but with a heating gradient used in the production of conventional Portland cement up to 1450 ° C, preferably temperatures in the lower range of this range, annealing within 20 minutes, preferably 5 to 10 minutes, in air or atmosphere of a steam-enriched furnace, cooled and milled in ball mills, then subjected to invasive grinding or the sebelite clinker is ground intensely in the cold or hot state, or the belite clinker becomes opacified after annealing with a cooling gradient of greater than 500 E / min, or coagulated. 2. The process according to claim 1, wherein the hardening of the clinker is carried out with water. 5. The method of claim 1, wherein the hardening of the hot clinker is carried out with air or a mixture of air and water. Method according to Claims 1 to 5, characterized in that the clinking of the hot clinker is carried out by step cooling, preferably in a temperature range of 1550 to 1250 ° C as the upper temperature limit and 1000 to 800 ° C as the lower temperature limit. 5. A method according to any one of claims 1 to 4, wherein the furnace atmosphere contains, in addition to the water content, steam from the feedstock. Recognized by the invention based on the results of the expertise carried out by the Office of Invention and Patent, Berlin, (DD) 2 drawings
