Focusing on Cement Manufacturing Process and its History
The manufacturing of Portland cement is the most common type of cement formation which is used in the construction sector. It is a type of hydraulic cement invented by Joseph Aspdin of England in 1824. It was produced from a mixture of limestone and clay. It got its name due to its high resemblance to the Portland stone in England.
Limestone quarry, quarrying, cement raw materials
Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing. Limestone quarries are opencast mines. Often limestone appears as an outcrop right on the surface. At other times it is under an overburden that can vary in depth but is generally less than 3 metres thick.
