Limestone referred to as limestone, the carbonates calcite as the main ingredient. Sometimes contain dolomite, clay minerals and detrital minerals, gray, gray, gray, yellow, light red, brown and red color, hardness generally not severe reaction with dilute hydrochloric acid. Limestone in metallurgy, building materials, chemical industry, light industry, construction, agriculture, and other special industrial sectors are important industrial raw materials. With the development of the steel and cement industries, will further enhance the importance of limestone.
Limestone as a mineral resources development and utilization is not be underestimated. In limestone mine construction investment, low technology content and obsolete equipment, serious pollution have all become factors restricting the development of the limestone industry.The rocks in the overburden may also contain calcareous material. The dissolution of these minerals, which may include CaCO3, MgCO3, and Ca, Mg(CO3)2, by natural waters produce alkaline drainages with attendant amounts of calcium and magnesium. The rate of dissolution of calcareous material is dependent on the pH, the partial pressure of carbon dioxide (PCO2), surface area of reactivity, temperature, rate of water flow and the frequency of contact between the water and the minerals (Rauch and White, 1977; Geidel, 1979). Equilibrium conditions are attained quickly, but the solubility of these minerals at atmospheric conditions is much less than the solubility of sulfide minerals. This often results in situations where the alkalinity is overwhelmed by the acidity.
Limestone mine utilization need jaw crusher chunk of stone crushing processing after impact crusher or cone crusher and other equipment for further processing, and then, depending on the industry, for different purposes during deep processing . Limestone ore crushing processing equipment generally hammer crusher, jaw crusher, impact crusher, cone crusher, impact crusher, mobile crushing station.
Cone crusher, widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Used in building materials, bricks, coal, metallurgy, mining, electric power, light industry and other industrial sectors for crushing coal, shale, coal cinder, carbon, lime, cement Guessed, bentonite and in hard brittle materials, crude broken, broken bits and pieces.
Henan Hongxing Machinery limestone crusher to spare no effort in the process of development of the limestone industry, support for the sake of further breakthroughs and make unremitting efforts.
