Sugar production | Carmeuse
Lime is used to capture and remove impurities in the juice of sugar beets. 125kg of limestone are used for the production of one ton of sugar. Most sugar-processing plants have their own lime kilns, so they need good-quality limestone to burn. The high calcium limestone is converted into quicklime in these lime kilns, at a temperature of 900°C.

How does a Lime Kiln Work
To produce quicklime in lime kilns, there are mainly three processes. The first stage is preheating. The second stage is calcining. And the third stage is cooling. In the preheating stage. The feed limestone is preheated by the exhaust hot air from the lime kiln, so that partially of the limestone will be calcined.
Modern Technological Applications for Limestone Mining
An alternative to the conventional drill and blast method is the use of rippers. Rippers can be used for limestone mining as limestone is a 'rippable' sedimentary rock (refer to Sect. 3.1.1) Using rippers in small mines or for a group consisting of more than one mine is economical and productive.
How is concrete made from limestone? | Shelly Company
It is mixed with water, sand and crushed rock to create concrete. The water, added through a process called hydration, starts the chemical reaction that causes the cement to harden and set, holding all of the ingredients together as concrete. Before the concrete is allowed to harden, the concrete mix must be poured into a mold so that it will ...
