Dear Benedict,

thank you for your question!

Heavy calcium carbonate is grinding powder from natural carbonate minerals such as calcite, marble and limestone. It is a common powdery inorganic filler. Commonly used heavy calcium powder fineness is 325 mesh, 400 mesh, 800 mesh, 1000 mesh, 1250 mesh and other specifications.

10 microns is also 1250 mesh, the size belongs to ultra-fine powder processing category. Liming Heavy Industry developed and produced professional ultra-fine powder processing equipment, LUM Series Superfine Vertical Roller Grinding Mill and HGM Series Micro Powder Mill for 10 microns(1250 mesh) ultra-fine heavy calcium carbonate powder processing.

The outstanding advantage of LUM Series Superfine Vertical Roller Grinding Mill is advanced capacity. It broke through the ultra-fine powder production bottlenecks, is suitable for large-scale heavy calcium carbonate, limestone, barite, gypsum and other ultra-fine powder production. The final product fineness is adjustable between 400-1250 mesh. HGM Series Micro Powder Mill has the advantage at finished size, the output size up to D97≤5 microns (2500 mesh).

Customers can choose the most practical equipment model according to the product fineness, capacity and other actual demand.
