presentation of the cement-making process
The given diagrams depicts the process by which cement is produced for making concrete which is objective of construction.
In general, both of cement and concrete are made by complex procedures; furthermore, the procedures need 5 and 1 kinds of machine in the complex procedures of cement and concrete, respectively. Aside from that, cement production needs merely 2 kinds of material, whereas concrete production need 4.
In the first step of producing cement, there is the crush phase, in which limestone and clay use crusher making powder, the second being the powder mixing through the mixer. Then the third step using rotating heater to heat up all of the mixing powder. As the final step, all of materials through the grinder become the finished good of cement after heating.
Regarding the second diagram of concrete production, there are 4 kinds of material with specific percentage. For example, gravel is the main material of concrete which occupies halt of percentage. Unlike gravel needs 50%, sand, cement and water which just meed 25%, 15% and 10%, respectively. Gathering all of the materials in the concrete mixer and the final product will be complete; what's more, this kind of merchandise will be applied on construction purpose.
I really appreciate any help. Thank you very much. :)))
