The diagram illustrates the step by step process of how cement is produced in a factory,from collecting raw materials to storing and transporting the final product.
Overall,the production of cement involves seven main stage,starting with quarrying and ending with the storage of cement. Focus on heating and cooling. The final stages involve grinding and distributing the finished cement.
In the first stage,limestone and clay are taken from the ground. These large rocks are then carried to a crusher,where they are broken into smaller pieces. After that,the materials are then mixed and heated in a rotary kiln at a very high temperature producing clinker,a hard ,small sized substance.
Next,the hot clinker is quickly cooled in a cooler to make it hard and stable. After cooling, the clinker is ground again and mixed with gypsum, which helps control the setting time of the cement. Finally, the finished cement is stored in large silos and then transported by trucks or ships to customers and construction sites.
