Product Performance & Advantages
Our 200 mesh dolomite powder adopts strict ore selection, coarse crushing and multi-stage screening technology, with pass rate stably controlled at 92%-99.993%. The product features uniform coarse particle size, no agglomeration and ultra-low moisture. With standard CaO content (27–35% per TDS TDHX-Dolomite-2025-08), it has excellent acid-base neutralization and chemical stability. It boasts high bulk density and low oil absorption, allowing large-dose filling to effectively reduce enterprise production costs. It can significantly improve the hardness, wear resistance and structural stability of finished products, with strong weather resistance and long service life.
Ultra-Wide Application Scope
200 mesh dolomite powder is mainly used for bulk industrial filling and construction engineering scenarios. In the construction industry, it serves as core filler for building mortar, concrete and road base materials. In environmental protection industry, it is widely applied in industrial flue gas desulfurization and sewage treatment. It is also commonly used for rubber and plastic bulk filling, ceramic raw material preparation, fertilizer additives and various general industrial filling fields, with extremely high cost performance and wide applicability.

Frequently Asked Questions
What are the CaO and MgO contents of your dolomite powder?
Our dolomite standard TDHX-Dolomite-2025-08 specifies CaO 27–35%, MgO 22–30%, SiO₂ ≤8%, Fe₂O₃ ≤0.5% and whiteness 80–95. Individual grades sit inside that window; the TDS is available for download on this page. Tell us your target chemistry and we will confirm which grade matches.
Which industries use dolomite powder?
Glass and ceramics (CaO–MgO source), coatings and plastics (functional filler), construction (mortar and concrete), and environmental protection (flue gas desulphurisation).
Why is dolomite powder used in glass melting?
Dolomite supplies both CaO and MgO in one raw material, which lowers the melting temperature, aids refining, and improves the thermal and chemical durability of the finished glass.
Can dolomite powder be customised for my process?
Yes — mesh size from 200 to 2000 mesh, whiteness 80–95, and CaO/MgO ratios can all be adjusted. Free samples are available for bench testing.
