The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.
The given two flow charts illustrate the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.
Overall, it is evident that there are five distinct stages to make the cement powder from crushing the limestones and clays to grinding to certain material. Also to make the concrete, some materials are mixed, including the cement.
Looking at the diagrams more closely, one can see that in the first stage to make the cement, the limestones and clays are crushed via a roller, and these become the powders. Then, these are blended into the mixer, following this, these mixtures are heated in the rotating heater with fire. After that, these are grinded by a grinder and become cement powder, and these are packed into the bags.
Meanwhile, to make the concrete, 15 percent of cement powder, 10 percent of the water, 25 percent of sand and 50 percent of gravel which are called small stones are needed. Then, these material are put into concrete mixer and mixed (반시계방향이라는 점을 넣어주시는 것도 괜찮은데, 전혀 중요한 사항은 아닙니다.), which is the process of concrete production.

이번 글 잘 써주셨습니다. 시간도 좋았네요. 실전에서 이정도의 80%만 쓰실 수 있어도 더할 나위가 없을 겁니다.
수고하셨습니다 :)
