Qiangda is one of the largest company offering wide range of Ground Calcium Carbonates in China. The pertaining raw materials occurs naturally & used in the form of calcite lime stone
Fine Ground Calcium Carbonate Powder is processed through naturally occurring high purity calcite ores containing CaCO3 as major component. The selected raw material has to be washed, crushed ,fine grinded and then classified precisely to attain the products of exceptional consistent & desirable quality available in a variety of grades.
Two processes are used to produce GCC
A dry process line (GCC), involves a series of crushing and fine milling stages that produces a fine (micronized) product. During the processing, the material is processed & classified in dry form to attain the desired quality of the products. Thefineness (D 50) of the standard products thus obtain is 2-5) microns.
In the wet process (WGCC), the coarser powder materials obtain initially from dry process used as the raw material. The powder raw material prepared in slurry form after adding the suitable additive then made to pass through stages of wet attrition mills to get ultrafine product slurry with low viscosity of close PSD band. The slurry has The calcium carbonate slurry thus obtained is filtered & supplied through tankers & barrels or packed in dried form.
