Critical Technical Requirements for Dolomite Grinding in Ceramics
Dolomite’s role in ceramics manufacturing extends beyond mere filler material. When properly processed, dolomite contributes to thermal stability, mechanical strength, and aesthetic qualities in finished ceramic products. The grinding process must achieve several technical objectives simultaneously: maintaining the chemical integrity of CaMg(CO3)2, producing consistent particle sizes between 325-2500 meshes, and avoiding iron contamination that could discolor finished ceramics.
Egyptian ceramics manufacturers typically require dolomite powders with specific characteristics: whiteness levels exceeding 90%, iron content below 0.02%, and tightly controlled particle size distributions that ensure uniform sintering during firing. These specifications eliminate many conventional grinding systems from consideration and demand advanced milling technology capable of precision grinding with minimal contamination.
