Limestone Mill High Efficiency Large Capacity 2002500

What is limestone. There are two types of lime: unslaked lime and slaked lime. Unslaked lime is lumpy, its main content is CaO, pure unslaked lime is white, unslaked lime with impurities is light gray or light yellow. Cement is made from mixture of limestone and clay etc. by high temperature calcining.

    How is concrete made from limestone? | Shelly Company

    Jan 29, 2014 · To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.

    Limestone is no more considered an inert material. World wide studies have shown that limestone takes part in hydration reaction and early strength development in cement. On the addition of limestone powder to cement, a reaction between CaCO 3 of limestone and aluminate phase of cement (C 3 A) takes place, which is quite similar to gypsum-C 3 A reaction.
