Hydrated Lime Manufacturing Process
The resulting lime is reacted (slaked) with water to form hydrated lime. The basic processes in the production of lime are: quarrying raw limestone; preparing limestone for the kilns by crushing and sizing; calcining limestone; processing the lime further by hydrating; miscellaneous transfer, storage, and handling operations.

Cement Manufacturing Process – NPC
Cement Manufacturing Process Phases: 1. Raw Material Extraction. Cement uses raw materials that cover calcium, iron and aluminum. Such raw materials are limestone, shale and sand. Limestone is for calcium. It is combined with much smaller proportions of dolerite, sand, and aluminium. Sand clay fulfil the need of silicon, iron and aluminum.

Manufacturing Process Of Cement Fujairah Cements industries
Pyro Processing and Clinkerization. The fuel is ignited and burned out in the combustion zone. The sintering process and the formation of clinker occur inside the kiln. Hot clinker is cooled in the cooler. Ambient air is used to cool the clinker and partially used for coal combustion. The cooled clinker is stored in the clinker yard/clinker silo for cement grinding.
