The diagram illustrates the production of cement using the dry process. Overall, the procedure consists of several main stages, starting with the extraction of limestone and ending with the packaging and transportation of the cement. The process is fully mechanised and relies on heating, crushing, and grinding to convert raw materials into fine powder.
First, limestone is quarried and sent to a crushing plant, where it is broken into smaller pieces. The crushed limestone is stored in silos before being mixed with ash and bauxite. This mixture is fed into a raw mill via a feeder silo for further processing.
Next, the material passes through a rotary kiln and is heated to around 1450°C, forming hot clinker. The clinker is cooled in a designated cooler and stored. Finally, it is ground into fine cement, stored in silos, and transported in bulk or in bags, with packaging machines filling bags for delivery by truck or train.
