A complete set of solutions for ground calcium carbonate milling

Project Background

Ground calcium carbonate (GCC), referred to as heavy calcium carbonate, is ground from natural carbonate minerals such as calcite, marble, and limestone. It is a commonly used powdery inorganic filler, with high chemical purity, high inertness, not easy to chemical reaction, good thermal stability, no decomposition under 400 ℃, high whiteness, low oil absorption, low refractive index, soft, dry, It has the advantages of no crystal water, low hardness, low abrasion value, non-toxic, tasteless, odorless, and good dispersibility.


Calcium carbonate is usually used as a filler, and is also widely used in artificial floor tiles, coatings, paints, inks, cables, rubber, plastics, papermaking, building supplies, food, medicine, feed, toothpaste and other daily chemical industries. The volume of the product reduces the production cost. Calcium carbonate is an essential pigment and filler. Calcium carbonate is not only easy to use, but also relatively cheap, making it the preferred pigment and filler.
 

Calcium Carbonate Milling Process

Ground calcium carbonate (heavy calcium carbonate) is obtained by directly crushing natural limestone, calcite, etc. by mechanical methods (grinding equipment such as Raymond mill or ultra-fine vertical mill). Its production methods include dry method and wet method. At present, all domestic products are produced by dry method.

Processing Advantages of HGM Ultrafine Grinding Mill

The HGM ultra-fine grinding mill is mainly suitable for ultra-fine powder processing of non-flammable and explosive brittle materials with medium and low hardness, Mohs hardness ≤6, such as calcite, chalk, limestone, carbon black, kaolin, bentonite, talc , mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alumite, graphite, fluorite, phosphate rock, potassium More than 100 kinds of materials such as ore, pumice, etc., the particle size of the finished fine powder can be adjusted arbitrarily between 325-3000 mesh, and the output can reach 0.4-4.5 tons per hour.

 

1. High productivity and low energy consumption

The output of the ball mill is more than doubled, and the energy consumption of the system is only 30% of that of the jet mill.

2. The fineness can be adjusted arbitrarily

The product fineness can be adjusted arbitrarily between 325 meshes and 2500 meshes.

3. Safer to run

There is no problem that the bearing and its seals are easily damaged, and there is no problem that the screw is easy to loosen and damage the machine; the production is safer.

4. High level of environmental protection

The production is organized in full accordance with the national environmental protection standards to meet the national environmental protection production requirements.

5. High machining accuracy

Digital control, high processing precision, and some core components are accurate to one or even higher standards.

6. Original spare parts supply

Provide customers with technical services and original parts supply services throughout the product life cycle.


 

Industry Uses of Calcium Carbonate Powder

As an important inorganic powder product, calcium carbonate is widely used in rubber, plastics, papermaking, coatings and other fields due to its wide range of raw materials, low processing cost, non-toxicity and high whiteness. , ink, toothpaste, cosmetics and other fields have a large number of applications. And with the progress and development of science and technology and the influence of relevant national policies, the use of calcium carbonate will become more and more extensive, and the demand will also increase.
