Cement manufacturing
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the ''raw feed'' or ''kiln feed'' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Role of lime stone in cement?
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

CEMENT RAW MATERIALS
The raw materials used in cement manufacture are extracted in large quarries, typically with outputs of up to, or over, 2.5 million tonnes per year. Typically about 1.65 tonnes of limestone (1.5 to 1.8 tonnes) and 0.4 tonnes of clay are quarried for each tonne of cement produced. Large reserves of feedstock, particularly of limestone, are

The Cement Manufacturing Process
Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called

The Brighton Limestone provided limestone for cement manufacture from 1882 to 1952. The first cement was manufactured in Australia in 1882 when William Lewis opened a small kiln at Brighton, a southern suburb of Adelaide, using limestone from the nearby Linwood Quarry. Supplies were supplemented from quarries in the same formation at Reynella which were linked to the plant by flying fox aerial
