Calcium Carbonate

Three types of calcium carbonate-containing rock are excavated and used by industry. They are limestone, chalk and dolomite. Limestone and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. The calcium carbonate rock could be extracted by blasting, crushing and grinding process.

DETAIL

Major components: CaCO3

Mohs hardness: 3.0-3.5

Applications: Building & Construction, Metallurgical

Calcium Carbonate Process Flow

  • 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.
  • 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.
  • 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.
  • 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.

Calcium Carbonate Processing Machine

Because of its vertical structure, ultrafine mill covers a little area, in this way, it help investors save lots of fundation and workshop costs. Also, its compact structure, perfect transmisson device and excellent sealing system can ensure its reliable performance and long service-life.

Vertical roller mill has similar working principle &outside surface with Raymond mill, but it has many more advantages, such as, higer grinding efficiency, higher capacity and fewer noises. So it is much more cost-efficiency and much more environment friendly used in calcium carbonate prodution line.
