illustrate a diagram The two diagrams illustrate the process of making cement and then the concrete production. Overall, the limestone and clay pass through four pieces of equipment before being bagged ultimately in the form of cement, which is applied with additional materials in the production of concrete.In the first production, limestone and clay are employed together through the crusher at the beginning point. Then the powder is transmitted through tubes from the mixer to a rotating heater, which heats the mixture by using fire constantly. The grinder plays an important role of making the powder into cement. Finally, the cement is packaged into the bags of standardized size. Regarding the second diagram, cement is then involved into the production of concrete, which helps constructing buildings. To produce concrete, three ingredients are also necessary besides cement and the proportion of each element is quite accurate. 10 percent of water and 50 percent of gravel consist of the three-fifth of the concrete mixture. 15 percent of cement and one-fourth sand are as well added into the giant container. At this time, concrete is taken into shape after several stages and various equipment. By comparison, the stages of producing cement is more tedious and time-consuming while concrete is formed in a mixture.
