The figures illustrate the levels and tools used for manufacturing
cement
followed by producing concrete in a factory.
Overall
, the cement
process consists of six stages from crushing to mixing and heating packaging. In concrete production, we see how some materials are mixed together.
According to
the figure for cement
production, first of all, both limestone and clay will be crushed by a roller and will changed into powder. Secondly
, this
powder will be mixed in a pipe and will be flowed in a rotating heater to be dried by heating. Then
after, it will be poured on a conveyer and will be grinned to be cement
. Finally
, it will be packed in bags.
It can be seen that in the concrete process, they mix 15% cement
, 10% water, 25% sand, and 50% small stones which is called gravel in a concrete mixer to combine all the items by rotation movement.Submitted by brightstargalaxy on
