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

We process marble ore through beneficiation, coarse crushing, medium crushing, grinding, 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 a soil acidity neutralizer. It is also employed 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 enhancer, widely used in: putty powder, lime, 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 (calcium carbonate powder, calcite powder) with uniform particle distribution, high brightness, and stable chemical composition.

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