This is done by a mixture of both air-cooling and water-cooling, including spraying water inside the mill. Cement milling and gypsum dehydration Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4 .H 2 O.
Need for Bulk Material Handling Plants with Conveyors Our present civilization requires producing innumerable items for comfort of people in a very large quantity. These items are produced from raw materials from planet earth with appropriate processes. For example, we need huge quantity of cement, which is made from mined materials.

The method of grinding cement may also influence the hydration kinetics. Cements ground in high pressure roller mills set faster than in ball mills, because of higher reactivity of C 3 A and C 3 S phases, and a lowered rate of decomposition of CaSO 4. Figure 2: Progress of cement hydration. Composition of pore solution

Elemental Analysis of Cement. Eltra. Applications. Knowledge Base. To produce high-quality cement, the mineralogical and chemical composition of raw materials as well as intermediate and finished products has to be determined. At each stage of the production, samples have to be taken, processed and analysed to ensure quality control without gaps.
Raw materials (ingredients, processing aids, and packaging materials) are the foundation of finished food products. As such, they must meet regulatory requirements (safe and legal for your intended use) and your specifications (contribute to the functionality and quality of your process and product).
