The larger-grained limestone is returned to the cone crusher and crushed again; the medium-sized limestone is sent to the next process. Third stage: fine crushing. Fine crushing and shaping is mainly completed by sand making machine or limestone sand making machine. First, the medium-sized limestone is sent to a sand making machine …

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times.
Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made.
Lime is used to convert iron into 'pig iron'. In the blast furnace, finely ground or granular limestone (with a low sulfur and alkali content) is used together with finely ground lime to convert ore into pig iron. The pig iron is later processed into steel. Lime is used as a fluxing agent in electric arc furnaces and basic oxygen furnaces.
