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

Calcined marble ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce marble powder. White marble is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizers, and as a filler for rubber and pharmaceuticals, as well as a soil acidity neutralizer. It can also be used as a metallurgical flux, building stone, refractory material, and as an ingredient in ceramics and glass. Metal magnesium can also be refined from it. It is a widely used inorganic filler material, serving as an excellent performance modifier and is extensively employed in: spackle, lime plaster, 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 (heavy calcium powder, calcite powder) with even particle distribution, high whiteness, and stable chemical composition.

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