Production process of light calcium carbonate_ Calcium carbonate mill
Light calcium carbonate is produced by calcining limestone and other raw materials to produce lime (mainly calcium oxide) and carbon dioxide, then adding water to digest lime to produce lime milk (mainly calcium hydroxide), and then adding carbon dioxide to produce calcium carbonate precipitation, which is then prepared by dehydration, drying and crushing, or first using sodium carbonate and calcium chloride for double decomposition reaction to generate calcium carbonate precipitation, and then dehydration It is made by drying and crushing.
After drying, light calcium carbonate needs to be crushed by a crusher and grinded by a grinder!
Crushers commonly used for crushing light calcium carbonate include hammer crusher, impact crusher and cone crusher. For large pieces of light calcium carbonate to be crushed, jaw crusher will be used for primary crushing. Crushed light calcium carbonate needs to be grinded by a mill. As for the selection of the mill, the fineness of the finished light calcium carbonate needs to be considered. If the fineness requirement does not exceed 500 meshes, it is recommended to select LM vertical roller mill, MTW European version mill and Raymond mill; If the fineness is required to be about 1000 meshes, it is recommended that you choose LUM ultra-fine vertical mill, MW medium speed mill and overpressure trapezoidal mill; For those manufacturers of light calcium carbonate that have strict requirements on the fineness of light calcium carbonate and reach 2000 goals, it is better to choose T130X enhanced superfine mill independently developed by Henan SMMVIK, which can not only improve the quality of finished products, but also the output of finished products.
