Grinding and the addition of gypsum Once the nodules of cement clinker have cooled, they are ground back into a fine powder in a large grinding mill. At the same time, a small amount of calcium sulfate such as gypsum (calcium sulfate dihydrate) is blended into the cement.
On the European Conference on Grinding (ECG), in its sixth edition by now, recent trends on grinding technology will be presented. The developments in grinding technology are diversifying continentally, so that presentations about the abrasives market in Europe, North America and Asia will be held by renowned experts to give an international overview to all conference attendees.
Cement grinding and packing process. The clinker is ground with an amount of gypsum to a fine powder in order to regulate the setting time of cement and to gain the most important property of cement, which is compressive strength. To produce different types of cement (e.g. Portland Pozzolana Cement), the required additives are ground with clinker...
