Liaoning Heavy Calcium Powder, Haicheng Heavy Calcium Powder, Heavy Calcium Carbonate Powder, Liaoning Calcium Carbonate Powder, Haicheng Calcium Carbonate Powder, Super-fine Calcium Carbonate Powder

White marble ore is processed through beneficiation, coarse crushing, medium crushing, pulverizing, grading, and packaging to produce white marble powder. Dolomitic limestone is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizer, lightweight magnesium carbonate, granular fertilizer, and as a filler in rubber and pharmaceuticals, as an acid neutralizer for soil. It can also be 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 filler material and an excellent performance enhancer, widely utilized in: spackling powder, white emulsion, paint, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields. Our factory produces various grades of ultra-fine heavy calcium carbonate powder (heavy calcium powder, calcite powder) with even particle distribution, high whiteness, and stable chemical composition.

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