Liaoning Heavy Calcium Powder, Haicheng Heavy Calcium Powder, High-purity Calcium Carbonate Powder, Liaoning Calcium Carbonate Powder, Haicheng Calcium Carbonate Powder, Ultra-fine Calcium Carbonate Powder

Calcium carbonate ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce calcium carbonate powder. Dolomite is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, and as a filler for rubber and pharmaceuticals, as well as an acid neutralizer for soil. It is also used as a metallurgical flux, construction stone, refractory material, and as an ingredient in ceramics and glass. It can also be refined into magnesium metal. It is a widely used inorganic filling material, an excellent performance modifier, widely applied in: spackling powder, white paint, paints, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields. Our factory produces various specifications of ultra-fine heavy calcium carbonate powder (calcium carbonate powder, calcite powder) with uniform particle size distribution, high whiteness, and stable chemical composition.

Our factory produces a variety of ultra-fine heavy calcium carbonate powder (calcium carbonate powder, calcite powder), all processed from dolomite or calcite ore. The product fineness ranges from 325 mesh to 2500 mesh, featuring even particle distribution and good brightness.
