Grinding & Classifying Systems

  • CaCO3 Grinding Systems

    Ground Calcium Carbonate (GCC) is mainly sourced from marble, limestone and chalk. The ultra-fine grinding of calcium carbonate produces properties such as whiteness and brightness. It is a highly functional filler and pigment for paper, plastic and paint products, and an ingredient of cement and iron purification. Pendulum mills are used for grinding calcium carbonate and other industrial minerals mainly for coarser products. Due to new developments, the production of ultra-fine particle size distributions with 97% <10 μm or finer is now possible; a particle size d50 <3μm can be achieved.
