PHASE 3: FINAL GRINDING Cement mill. The clinker is then grounded very finely in a cement mill with other additives (ash from thermal power plants, blast furnace slag or gypsum) to obtain different quality of cement. The cement is then stored before delivery. Instrumentation for cement mill: Fuel and gas flow measurement for cement mill

grinding the resulting clinker to make cement (see Cement mill). In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot gases from combustion of the kiln fuel. Successive chemical reactions take place as the temperature of the rawmix rises: 70 to 110 °C Free water is evaporated.

By. admin. Clinker grinding technology is the most energyintensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning ...
