The light calcium carbonate is important raw materials for industry such as papermaking, rubber, plastics and paint manufactory. This technology is to utilize the principle of CO2 carbonation to produce light calcium carbonate, employ calcium oxide and CO2 as raw materials with rotating packed bed reactor in the different conditions that include no additive, conditions of operation control to continuous produce different crystal form calcium carbonate. This technology emphasis on doesn’t adding any additive, it so will not influence purity of calcium carbonate. In addition to, it can continuous production, easy to operate and low cost.
