The main mineral component of limestone is calcite. It has rare crystal structure and mineral particles and its surface is smooth and granular. Colors are black, gray, white, yellow and brown. Limestone containing seawater formation lime, hence the name of marble, limestone, chalk, rock, etc. Their main component of natural mineral is calcium carbonate.
Limestone is a non-renewable resource, with the continuous progress of science and technology and the development of nanotechnology; Limestone application areas are further widened. After crushing by crusher and sand making machine, limestone can be applied in many fields. Limestone powder processing industry is gradually vigorous in recent years.
Limestone can be directly processed into stone and fired into the quicklime. It includes quicklime and slaked lime. Cement is made from limestone and clay mixed by high temperature calcination system. Glass is made from the limestone, quartz sand, soda ash and other mixed by high temperature melting system. Smelting Iron is with limestone for flux and removing gangue. Steel making use lime as slag material to remove sulfur, phosphorus and other harmful impurities.
