Physical Testing of Quicklime, Hydrated Lime, and Limestone
The different chemical compounds that fall under the overarching term "lime"—quicklime, hydrated lime (slacked lime), and limestone—are sharply related, with quicklime being produced through the thermal decomposition of limestone (by heating in a kiln) and hydrated lime deriving from the mixing, or "slaking," of quicklime with water to transform …

Lime
The excavation of rock for lime production is normally undertaken in a quarry with the use of explosives or mechanical rock breaking hammers, although for very small-scale lime production hand excavation methods may still be used. In most lime kilns, the raw materials must be broken down to a standard size, typically between 100 and 150mm. This

(PDF) An empirical study of factors influencing lime slaking.
Limestone (mainly CaCO 3 ) is one of the most widely occurring industrial minerals world-wide. It is therefore not surprising that lime, obtained by calcining limestone, is a frequently used industrial base and features on the list of the top 50 industrial chemicals (National Lime Association, 1990).
