Precision and Purity in 200 Mesh Dolomite Powder: Engineering-Grade Mineral by Kiran Minichem

In the world of mineral processing and industrial formulation, 200 Mesh Dolomite Powder stands as a benchmark of controlled particle size, chemical uniformity, and structural integrity. Produced by Kiran Minichem, a reputed Wholesaler and Wholesale Supplier, this high-purity dolomite grade serves as a multifunctional additive and filler across diverse industrial sectors including glass, ceramics, paints, polymers, fertilizers, and steel.

With meticulous attention to mesh sizing, particle fineness, and mineral purity, Kiran Minichem ensures every batch of Dolomite Powder meets the stringent requirements of modern industrial applications where precision governs quality and performance.

Understanding 200 Mesh Dolomite Powder

Dolomite (CaMg(CO₃)₂) is a double carbonate of calcium and magnesium, valued for its dual chemical functionality and thermal stability. The 200 mesh grade indicates that the powder has been finely ground to pass through a 200-mesh sieve, ensuring a particle size distribution around 74 microns. This fine mesh size enhances reactivity, dispersion, and blending characteristics in formulations.

Kiran Minichem utilizes advanced pulverizing and micronizing systems to achieve consistent mesh size distribution and high surface reactivity, ensuring that the final product performs reliably under diverse processing conditions.

Chemical Composition and Purity Standards

Every batch of 200 Mesh Dolomite Powder from Kiran Minichem undergoes rigorous laboratory analysis to confirm the following parameters:

  • Calcium Carbonate (CaCO₃): 54% – 56%
  • Magnesium Carbonate (MgCO₃): 42% – 44%
  • Silica (SiO₂): < 0.5%
  • Iron Oxide (Fe₂O₃): < 0.2%
  • Moisture Content: < 0.2%
  • Whiteness Index: 90% – 95%

These values represent an optimized mineral balance, ensuring both structural integrity and chemical compatibility across end-use industries. The controlled magnesium and calcium ratios make this Dolomite Powder particularly effective as a fluxing, neutralizing, and reinforcing agent.

Manufacturing and Mesh Calibration Process

Kiran Minichem employs precision-driven techniques to achieve the 200 mesh fineness while maintaining consistent density and morphology. The process involves:

  1. Raw Material Selection: High-grade dolomite lumps sourced from reliable quarries with minimal impurities.
  2. Primary Crushing: Breaking down large dolomite rocks into manageable aggregates.
  3. Grinding and Pulverization: Multiple-stage grinding through ball mills and classifiers to attain 200 mesh fineness.
  4. Air Classification: Ensures uniform particle size and removes over-ground particles.
  5. Magnetic Separation: Eliminates ferrous contaminants for higher chemical purity.
  6. Quality Inspection and Packaging: Testing for brightness, mesh consistency, and reactive index before final dispatch.

This controlled workflow guarantees reproducibility and uniformity in every shipment, meeting ISO and ASTM standards for industrial mineral products.

Applications in Industrial Sectors

The 200 Mesh Dolomite Powder finds extensive applications due to its balanced chemistry and fine mesh size:

  • Glass Manufacturing: Acts as a fluxing agent, improving melt viscosity and glass clarity.
  • Ceramics: Enhances firing characteristics and thermal stability in tiles and sanitary ware.
  • Paints and Coatings: Serves as an inert filler, improving opacity, gloss, and surface smoothness.
  • Plastics and Rubber: Provides reinforcement and dimensional stability.
  • Steel Industry: Used as a flux during sintering and refining to control slag chemistry.
  • Agriculture: Neutralizes acidic soils and supplements magnesium and calcium nutrients.
  • Water Treatment: Used as a buffering agent to maintain pH stability.

By offering chemical consistency and reliable supply, Kiran Minichem ensures that the 200 Mesh Dolomite Powder fits seamlessly into every industrial process requiring precision-grade mineral input.
