Limestone crushing process
As the entire cement manufacturing process is very complex, so I can only briefly limestone crushing process. There are so many different types of limestone crusher, I will choose impact crusher, for example, a brief explanation. Impact crusher mainly rely on the chamber in a strong blow on the ores, ore on the back liner impact collision between leaving and ore ore crushing. Ore fed through the entire feeder crusher feed port after the fall of the two V-belt drive between the rotor speed counter-rotating crushing cavity blow by the hammer is initially broken. Broken the downward movement of the rotor and the strike plate in the order early course material will further disconnect and then hit the board again after diversion order, namely two mutually symmetrical discharge area, and finally the formation of the lower grate and chamber rotor crusher grate until the final sewing room size less than the size of the discharge from the lower.
Calcium, the element of highest concentration cement, is obtained from a variety of calcareous raw materials, including limestone, chalk, marl, sea shells, aragonite, and an impure limestone known as “natural cement rock”. Typically, these raw materials are obtained from open-face quarries, but underground mines or dredging operations are also used. Raw materials vary from facility to facility. Some quarries produce relatively pure limestone that requires the use of additional raw materials to provide the correct chemical blend in the raw mix. In other quarries, all or part of the noncalcarious constituents are found naturally in the limestone. Occasionally, pockets of pyrite, which can significantly increase emissions of sulfur dioxide, are found in deposits of limestone, clays, and shales used as raw materials for portland cement. Because a large fraction (approximately one third) of the mass of this primary material is lost as carbon dioxide (CO2) in the kiln, cement plants are located close to a calcareous raw material source whenever possible. Other elements included in the raw mix are silicon, aluminum, and iron. These materials are obtained from ores and minerals such as sand, shale, clay, and iron ore. Again, these materials are most commonly from open-pit quarries or mines, but they may be dredged or excavated from underwater deposits.
