Aug 30, 2012 When material reaches the lower part of the kiln, it forms the shape of clinker. Cement Manufacturing Process Phase V Cooling and Final Grinding. After passing out from the kiln, clinkers are cooled by mean of forced air. Clinker released the absorb heat and cool down to lower temperature.
and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 8090% of

Kiln and Kiln Shells - As a Cement kiln manufacturers we manufacture all type of process equipments including Vertical and roller Kiln and Shells - Kiln Shells is involved in the process of burning the raw mixture thereby resulting in the clinker. This clinker is then subjected to grinding to produce cement.
Purbanchal Cement Ltd. (PCL) is engaged in the production of Clinkers and Cement. The lime stone is crushed in primary and secondary crusher and conveyed to the storage hopper. Each raw material/consumables such as crushed lime stone, additive and iron dust are weighed as per designed quantity and fed to raw mill for grinding.
Oct 03, 2017 (iii) Grinding. Grinding of the clinker is done in large tube mills which are kept cool by spraying water on them from outside. While grinding the clinker three to four per cent gypsum (Calcium sulphate) is added so as to control the setting time of cement. Finely ground cement is stored in silos from where it is drawn for packing.
