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

Calcined marble is processed through beneficiation, coarse crushing, medium crushing, pulverizing, grading, and packaging to produce marble powder. White marble is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizer, lightweight magnesium carbonate, granular fertilizer, as a filler in rubber and pharmaceuticals, and as a soil acidity neutralizer. 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 metallic magnesium. It is a widely used inorganic filling material and an excellent performance enhancer, widely utilized in: spackle, white paint, 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 ultra-fine heavy calcium carbonate powder (heavy calcium powder, calcite powder) in various specifications, all made from marble or calcite ore. The product fineness ranges from 325 mesh to 2500 mesh, featuring even particle distribution and good brightness.
