Our 300 Mesh Dolomite Powder is a microfine, ultra-pure mineral product specially processed to pass through a 300-mesh sieve (approx. 48 microns). It offers exceptional fineness, superior brightness, and high chemical stability, making it ideal for high-performance industrial applications.

Applications:

• Paints and Wall Putty: Used in manufacturing paints and wall putty, contributing to whiteness and smoothness.
• Steel Industry: Utilized in steel manufacturing processes.
  Detergent Cakes and Soap Manufacturing: Incorporated to enhance product quality.
• Agriculture: Applied as a soil conditioner.

• calcium and magnesium, enhancing plant growth.
• Ceramics: Enhances thermal and mechanical properties, improving resistance to heat and wear.
• Iron & Steel Industry: Serves as a flux to remove impurities during metal production, improving the quality of the final product.

Dolomite powder is available in various grades in the market, which are defined based on purity, mesh size, and its industrial application. Below are some commonly available grades of dolomite powder:

• High purity dolomite (CaCO3 + MgCO3 > 95%)
• Uses: Fertilizers, water treatment, glass manufacturing
• Mesh size: 100 to 300 mesh

2. Paint Grade

• Fine quality, high brightness
• Uses: Paints, coatings, primers
• Mesh size: 300 mesh and above

3. Ceramic Grade

• High whiteness and low iron content
• Uses: Ceramic tiles, sanitary ware
• Mesh size: 200 to 400 mesh

4. Steel Grade (Metallurgical Grade)

• Used in steel plants as a fluxing agent
• Lower silica content preferred
• Available in lump or powdered form

5. Construction Grade

• Used as filler in concrete and asphalt
• Lower purity acceptable
• Coarser mesh size (below 100 mesh)

6. Glass Grade

• High calcium and magnesium content with low iron
• Uses: Glass manufacturing
• Mesh size: Typically 150 to 200 mesh
