The diagrams below show the stages and equipment used in the coment-making process, and how coment is used to produce concrete for building purposes.

The two flow charts show the procedures for producing

cement

and concrete respectively.

Overall

, there are five stages for manufacturing

cement

, beginning from the input of raw materials to be packaged with final products, which will be translated into concrete by blending with other ingredients. When it comes to

cement

production, limestone and clay are poured into a crusher,

thus

being ground into powder, after which it will be delivered to the mixer. The mixture will be sent into the rotating heater, where it will be adequately mixed and heated. As transported by the grinder, the final product will be packaged in bags. With regard to concrete production, there are four materials that need to be added together, including 15% of

cement

, 10% of water, 25% of sand and half of small stones in the “concrete mixer” which is a kind of machine to produce qualified concrete. At

last

, the procedure ends with the output of concrete.
