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

The marble ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce marble powder. Marble is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, as a filler in rubber and pharmaceuticals, and 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 to produce magnesium metal. It is a widely used inorganic filling material, serving as an excellent performance enhancer and is extensively used 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 (heavy calcium powder, calcite powder), all processed from marble or calcite ore. The product fineness ranges from 325 mesh to 2500 mesh, featuring uniform particle distribution and good brightness.
