USES OF DOLOMITE POWDER
RUBBER PRODUCTS:
A huge market for dolomite is rubber industry manufacturing different products as footwears, container, etc.
CONSTRUCTION:
In a crushed manner it is used extensively in construction industry such as base of roads, aggregate in cement and filling in different manners. Rail road Ballast also invites huge usage of dolomite sand.
AS A STRAINER:
Used in hydro power plants to strain all the impurities from water when used as sand formation.
THERMAL POWER PLANTS:
Due to its high resistance to heat it is used in kilns for lining in the inside part and also exterior.
CERAMIC INDUSTRY:
Due to its hardness and high gravity it is used hugely in tiles and other ceramic based industries , as well as a sintering agent in iron ore pelletization and as a flux agent in steel making.
CHEMICAL INDUSTRY:
Due to use of MgO in pharma and other scientific purposes, dolomite is used in this industry also. Extraction of MgO from powder or chips os done through chemical processing by treating it with various acids.
Pure White Natural Dolomite is Micronized by adopting the latest Indigenous Technology and Manufacturing Plants under strict Quality Control. The ultimate fine and high whiteness Filler is available in Uncoated and Coated Form. The available particle size ranges between 40 ~ 10 Microns.
We are supplier and exporter of Dolomite. We provide all types of Dolomite "Crushed, Powder or Bulk" Product - Dolomite Ore Specification MGO: 20% min Caco3: 32% min Al2o3: 0.04% Fe2o3: 0.02% Shipping mode - Containerized or Bulk Packing olomite powder is an anhydrous carbonate mineral which comprises calcium magnesium carbonate. It finds its use widely in Plastic, in PVC footwear, PVC Pipes, cables and others. One of the most widely used Mineral Fillers in the Plastics and Polymer industry, and its use in rigid packaging has increased significantly over the years due to its low cost and abundance availability.
High purity Dolomite, i.e., with low silica content. The low silica dolomite powder is available in coated and uncoated form. The available particle size ranges between 40 ~ 10 Microns.
Dolomite mineral is a double carbonate of calcium and magnesium and it exhibits a granular structure. It has high natural whiteness and it's noted for their ease of dispersion. Its use improves properties such as weather ability, reduces shrinkage, fissure development and water absorption. Natural Dolomite Powder is of White Colour and is used as Filler in many applications such as Soap & Detergent, Paints, Ceramics and many other Industries. Applications: - Soap & Detergent Leather Cloth Industry Cable Industries Rigid PVC Pipes Iron, Steel, and Ferro-Alloys Industries Paints, Inks, Powder Coating Ceramic Industry Rubber Industry Glass Industry Available Mesh Size: - 100 TO 700 MESH Custom sizes and Material of required specifications can be made in case of Bulk and Regular orders.

Dolomite powder is used as a raw material for the production of high-grade glassware, medicine bottles and optical glass. Dolomite powder has limited dosage in paints, confined to be used as filler, mainly playing the role of white pigment. However, due to the coarse particles, refractive index and paint solvent similar to the covering power is weak, there is no certain special role in the application, just for the body pigment filler paint.- Used in the building materials and refractory materials, chemical and agricultural, environmental protection, energy conservation and other fields. - Used in the production of glass and ceramic ingredients; - Used as refractory inner layer, slag making agent, cement raw material, glass flux, kiln industry, building and decoration stone material, paint;
