Ground Calcium Carbonate(GCC) is usually got by grinding natural carbonate minerals such as calcite, marble and limestone. It is a kind of common powdery inorganic fillers, characterized by high purity, big inertia and excellent thermal stability. GCC never decomposes below 400℃. Besides, it has advantages such as high whiteness, low oil absorption, low refractive index, low hardness, low abrasion value and good dispersion. GCC is soft, dry / water-free, non-toxic, tasteless and odorless.

Ground Calcium Carbonate(GCC) Grinding Technical
Ground Calcium Carbonate(GCC) is usually made by grinding natural carbonate minerals such as calcite, marble and limestone. It can be got by wet or dry process. Currently, dry process is popular at home.
1. Crushing Stage:
Big blocks of natural carbonate minerals like calcite, marble or limestone would be crushed into particles within 15mm-50mm --- the feeding size of grinding mills.
2. Grinding Stage:
The small qualified pieces would be evenly sent, by conveyor and feeder, into the grinding cavity where the materials would be ground into powder.
Usually, LM vertical grinding mill, MTW European grinding mill and MTM over-pressure trapezoidal grinding mill are often used for fine powder processing while LUM ultrafine vertical grinding mill and XZM ultrafine grinding mill are often used for ultrafine grinding.
3. Grading Stage:
The ground Ground Calcium Carbonate(GCC) with air flow would be graded by powder separator. After that, the unqualified powder would be sent back to the grinding cavity for another grinding.
4. Powder Collecting Stage:
With air flow, powder meeting the standard enters into the powder collecting system along the pipe. The finished powder products are sent to finished product warehouse by conveyor and packed by powder filling tanker and automatic pack machine.
GCC Can Be Used In:
2. Paper industry
3. Chemical engineering
5. Adhesives and sealants
8. Feed industry
