Ground Calcium Carbonate(GCC) is usually got by grinding natural carbonate minerals such as calcite,
and limestone. It is a kind of common powdery inorganic fillers, characterized by high purity, big
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
GCC is soft, dry / water-free, non-toxic, tasteless and odorless. In terms of granularity, GCC can
classified into ordinary GCC, ultrafine GCC, wet-grinding ultrafine GCC and surface-modified
Ground Calcium Carbonate(GCC) Grinding Technical
Ground Calcium Carbonate(GCC) is usually made by
natural carbonate minerals such as calcite, marble and limestone. It can be got by wet or dry
Currently, dry process is popular at home.
Big blocks of natural carbonate minerals like calcite, marble or limestone would be crushed
particles within 15mm-50mm --- the feeding size of grinding mills.
The ground Ground Calcium Carbonate(GCC) with air flow would be graded by powder separator.
that, the unqualified powder would be sent back to the grinding cavity for another grinding.
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
SCM ultrafine grinding mill are often used for ultrafine grinding.
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
How to match a calcium carbonate plant
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.
