The Hydration Process
In the presence of water,
in some certain proportions,
the quicklime is hydrated, according
to the reaction:
As it is shown in the equation above,
the hydration process is strongly exothermic, which
causes a very fine natural pulverization of the product.
The product so obtained is called hydrated lime on
For the industrial realization of
this process, an apparatus
denominated hydrator is used. It is equipped with a
series of devices for
the control of the hydration reaction and of the humidity
of the moisturized
lime. The resulting product should later on be subjected
to a highly efficient separation process to achieve
a final product with a grain size below 60 microns..
