Step 1: Mining. The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km. The limestone is excavated from open cast mines after drilling and blasting and loaded ...

Stage 2: Grinding, Proportioning, and Blending The crushed raw ingredients are made ready for the cement-making process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture. The composition of cement is proportioned here depending on the desired properties of the cement. Generally, …

Modern dry-process cement plants with an efficient grinding and pyro processing system, typically consume less than 700 kcal/kg-cl of thermal energy and 100 kWh/mt of electrical energy. Older plants with inefficient systems, combined with operational and maintenance failure, tend to have much higher energy consumption.
