Liaoning Heavy Calcium Powder, Haicheng Heavy Calcium Powder, Heavy Calcium Carbonate Powder, Liaoning Calcium Carbonate Powder, Haicheng Calcium Carbonate Powder, Ultra-fine Calcium Carbonate Powder

Wolframite ore is processed through beneficiation, coarse crushing, medium crushing, grinding, classification, and packaging to produce dolomite powder. Dolomite is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, as a filler for rubber and pharmaceuticals, and 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 filler material. It is an excellent performance enhancer and is widely used in: putty powder, white paint, paint, 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 ultra-fine heavy calcium carbonate powder (heavy calcium powder, calcite powder) in various specifications, all processed from dolomite or calcite ore. The product fineness ranges from 325 mesh to 2500 mesh, featuring uniform particle distribution and good brightness.
