Limestone, which is primarily calcium carbonate, is a sedimentary rock made from the minerals calcite or aragonite. A large portion of limestone is made from the skeletal remains of sea creatures and organisms. Ground Calcium Carbonate (GCC) differs from Precipitated Calcium Carbonate (PCC) in that the GCC is formed directly from grinding limestone rock into a powder, while PCC is chemically produced and precipitated out as powder.

Ground Calcium Carbonate is used in paper and plastic fillers, coatings and paints. It is also used in cement, is converted to quick-lime (calcium oxide) and slaked lime (calcium hydroxide). Ground calcium carbonate is slightly basic and can be used to neutralize combustion vapors or increase the pH in water or soils.

Pure calcium carbonate is a relatively soft mineral/compound, with a Mohs hardness of 2.5 – 3.0. However, mined limestone may have a minor portion of abrasive impurities such as quartz / sand.

One of the standard methods of milling Limestone/Calcium Carbonate is with the Hengyang Ball Mill. Hengyang Industry has a rotating rotor disc with hammers which rotates with speeds up to 23,000 feet per minute. The particle size is controlled by the internal air classifier, to provide sharp particle size distributions. Various classifier designs are available, to produce from coarse (100 mesh) product down to a fineness of 635 mesh (20 µm) product or a D50 of less than 5 µm. Abrasion resistant options are available, including tungsten carbide tipping, Ni-Hard or Ceramic liners to assist with abrasive impurities and to assist with long life of mill components. Hot air can also be used to dry the product while milling.

An alternate to the ball mill for coarser grade Calcium Carbonate is the Mikro Pulverizer Hammer & Screen Mill. The Pulverizer uses swing-hammers with interchangeable screen liners to produce a variety of products from 50 mesh to 150 mesh products.

For ultra-fine (D50 < 5 µm) milling, the Hosokawa Alpine Super Orion Ball Mill and Air Classifier are the best option. These units come in a variety of sizes to meet your application needs.

Wet milling with Hosokawa Alpine Agitated Ball Mill and is used to produce ultra-fine calcium carbonate slurries from 60% to 99% < 2 µm, at relatively low specific energy.

For plastic fillers, stearic acid coating on ground calcium carbonate is often performed.

Other Application:

Major rock types processed by the crushed stone industry include limestone, granite, dolomite, traprock, sandstone, quartz, and quartzite. Minor types include calcareous marl, marble, shell, and slate. Major mineral types processed by the pulverized minerals industry, a subset of the crushed stone processing industry, include calcium carbonate, talc, and barite. Industry classifications vary considerably and, in many cases, do not reflect actual geological definitions.
