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.

Oct 17, 2018· The raw material for the cement plant comes from a deposit located 15 km to the north. The Carpathian mining area is rich in sedimentary rocks such as limestone, marl and gypsum. Production increase thanks to Wirtgen technologies. For years, the material was extracted by drilling and blasting and then wet-processed into clinker in the cement plant.
The raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
