Ground Calcium Carbonate(GCC)
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. In terms of granularity, GCC can be classified into ordinary GCC, ultrafine GCC, wet-grinding ultrafine GCC and surface-modified ultrafine GCC.Calcium carbonate plant can produce calcium carbonate powder with different fineness between 80-2500 mesh，Calcium carbonate plant need to crushing equipment, milling equipment and some corresponding mining equipment work together, the way to match jaw crusher, hammer crusher,MTM series trapezium mill、modification machine, powder packaging machine, belt conveyor, vibrating feeder, etc.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.
