Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate production, in particular to a calcium carbonate drying tower used for calcium carbonate production. Background Art

[0002] Calcium carbonate is a white solid, tasteless and odorless. It has two forms: amorphous and crystalline. The crystalline form can be divided into orthorhombic and hexagonal systems, which are columnar or rhombic. The relative density is 2.71. It decomposes at 825-896.6℃, and decomposes into calcium oxide and carbon dioxide at about 825℃. The melting point is 1339℃, and the melting point is 1289℃ under 10.7MPa. It is difficult to dissolve in water and alcohol. It reacts with dilute acid and releases carbon dioxide at the same time, which is an exothermic reaction. It is also soluble in ammonium chloride solution. It is almost insoluble in water. Calcium carbonate is widely used in the pharmaceutical, papermaking, food, plastic and other industries.
