The two diagrams illustrate in an elementary form, from start to finish, how both cement and concrete are produced using varies raw materials, their percentages required, and specific machinery and mixing techniques.
Keep your introduction short and direct.
The two diagrams illustrate the process of how cement is produced from raw materials and the production of concrete for building purpose.
The first diagram, cement production, is set in motion by adding Limestone and clay to the crusher with the result then being transferred to the mixer.
In the first stage of cement making, limestone and clay are added to the crusher and then transferred to the mixer in the form of powder.
After this process stage, the mixture is then sent through the rotating heater, resulting in a product which is then grinded to produce the desired outcome of cement.
After that, the mixture is sent to the rotating heater and heated, the result of which is then grounded to produce cement.
The cement is ready to be bagged.
Packaging cement in bags is the final step of the process.
The second diagram,although easier in it's process, uses many more materials in it's making
To produce concrete, four materials are initially required.
