Best Calcium Carbonate Grinding Mill for Micro Powder Production

Introduction to Calcium Carbonate Grinding

Calcium carbonate (CaCO3) is a versatile mineral widely used in industries like plastics, paints, paper, and pharmaceuticals. Producing ultra-fine calcium carbonate powder requires advanced grinding technology to achieve precise particle sizes (325–2500 meshes) while maintaining energy efficiency. Among the available solutions, MW Ultrafine Grinding Mill and LUM Ultrafine Vertical Grinding Mill stand out for their exceptional performance in micro-powder production.

LUM Ultrafine Vertical Grinding Mill: A Smarter Alternative

For projects requiring even finer control, the LUM Ultrafine Vertical Grinding Mill offers:

  • 30–50% Energy Savings: PLC-controlled multi-head powder separator optimizes cutting precision and switching speed.
  • Reversible Roller Design: Hydraulic system allows easy maintenance without dismantling the mill.
  • Stable Material Layer Formation: Unique roller shell curve ensures consistent grinding pressure for higher whiteness (≥94%).

Applications & Case Studies

Both mills excel in processing calcium carbonate for:

  • Cosmetics: Ultra-fine powders (d50=2μm) for foundations and sunscreens.
  • PVC Pipes: High-purity CaCO3 improves tensile strength by 15–20%.
  • Food Additives: FDA-compliant powders with iron content <0.005%.
