Dolomite Powder Exporter
KBH Trade is a reliable supplier and exporter of high-quality Dolomite Powder from India, serving manufacturers, processors, distributors and industrial buyers across domestic and international markets.
Dolomite is a naturally occurring mineral primarily composed of calcium magnesium carbonate (CaMg(CO₃)₂). It is carefully processed and ground into fine powder for a wide range of industrial applications.
We offer both Dolomite Coated Calcium Carbonate and Dolomite Uncoated Calcium Carbonate in different grades, mesh sizes and particle-size specifications according to customer requirements.
Dolomite Uncoated Calcium Carbonate
Dolomite Uncoated Calcium Carbonate is a naturally derived mineral powder processed without surface coating. It contains naturally occurring calcium and magnesium compounds and is available in various mesh and particle-size grades.
Its natural mineral composition, fine particle size and versatile characteristics make Uncoated Dolomite Powder suitable for construction materials, ceramics, glass, paints, rubber, agriculture and other industrial applications.
