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

The marble ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce marble powder. Dolomitic limestone is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizers, 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. Metal magnesium can also be extracted from it. It is a widely used inorganic filling material and an excellent performance modifier, widely applied in: putty 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 (heavy calcium powder, calcite powder) with uniform particle size distribution, high brightness, 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.
