The Manufacture Of Portland Cement. The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1
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.

The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1
The cement manufacturing process is comprised of four main stages: extracting and grinding raw material, homogenising raw material, clinker production, and cement grinding. Moreover, the limestone considered for the production of aggregates must pass through several stages in a crushing and sorting system in order to produce the sizes required for marketing.

Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.
