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

White marble ore is processed through beneficiation, coarse crushing, medium crushing, grinding, grading, and packaging to produce white marble powder. White marble is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, and as a filler in rubber and pharmaceutical products, as well as a soil acidity neutralizer. 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 filler material, serving as an excellent performance modifier. It is extensively used in: putty powder, white emulsion, paint, plastic, 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 uniform particle size 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 processed from marble or calcite ore. The product fineness ranges from 325 mesh to 2500 mesh, featuring even particle distribution and good brightness.
