Microcalcite (ground marble)

Microcalcite: what is it

Calcium carbonate, microcalcite, micromarble, fine marble, marble flour, marble grits or ground marble - all these are the names of the most demanded building and chemical material in the world!

Read more about the benefits of using, production features and factors affecting the cost of ground marble.

Ground marble

Microcalcite production process

on the example of the plant "Basis"

Microcalcite is produced in marble grinding factories.

For the production of micromarble, crushed marble rock is used - usually a fraction from 0 to 80 mm.

These stones are fed to a mill, in which the marble chips are turned into fine marble powder.

To make the highest quality ground marble, only pure white marble chips should be used.

This is exactly what we do at the Bazis plant, organizing the sorting of raw materials by color.

Thanks to the air classification technology, our employees can easily customize the production of microcalcite of any required fraction.

Benefits of Using Calcium Carbonate

for different areas of production

1   2   3

Radiation safety. 

Calcium carbonate belongs to category 1 building materials, which means its purity, safety and applicability for interior construction work. 

High grain strength.

Calcium carbonate, in contrast to chalk, has a pronounced crystal lattice. 

As a result - increased strength and wear resistance of the final products.

Non-flammability, fire safety.

Microcalcite MK, due to its resistance to combustion, is recommended for use in children's, cultural, sports, medical institutions, in public and residential buildings.

Solubility in acids.

Such property of ground marble as solubility in mineral acids, for example, in hydrochloric acid, is very important for oilmen.

This is why microcalcite is used to complete oilfield services and to repair oil spills.

UV resistant.

This property is important for manufacturers of various types of building materials intended for exterior decoration of structures.

An important property. It should be remembered by manufacturers of dry building mixtures

Free from dyes.

Ground marble (MK, microcalcite) does not contain such impurities as titanium, manganese, iron oxide, etc., which can affect the final color of the product.

This is why it is chosen for white products.

Adhesive properties.

Microcalcite has high adhesion characteristics. In other words, the particles of ground marble adhere well to each other. This property is important for those who use calcium carbonate as the basis for any kind of solution.

Be it mortars, drilling fluids or grouting fluids.

Distinctive characteristics of micromarble

If you want to buy microcalcite and choose a supplier, we recommend that you carefully study our list of criteria or main characteristics of ground marble.

Seriously. Often the price of microcalcite is not the most important thing.

Trust our many years of experience.

Some of these features of micromarble may not be important for your type of production, while others may be the determining factors.

  • White
          ⇒

Whiteness depends on the purity of the original marble. As a rule, manufacturers make 2 types of micromarble according to whiteness: 

1st grade (from 95 to 99%) by whiteness

2nd grade (below 94%) for whiteness.

This parameter is important for manufacturers of varnish and paint products, finishing fillers, PVC products, etc.

 

  • Chemical composition
          ⇒

In this parameter, one should pay attention to the chemical purity of the product, the content of the basic substance (CaCO3) and impurities.

This factor will be important for the technologists of glass factories and other manufacturing enterprises. Therefore, if you are interested in buying microcalcite, check the chemical composition of microcalcite from the supplier.

 

  • Fractional composition
          ⇒

In other words, the size of the particles. The fineness of microcalcite grinding is important for everyone.

The size of the microcalcite fraction is indicated by a number and is calculated in micrometers (μm).

This parameter is indicated in the product quality certificate and other documentation.

 

  • Humidity
          ⇒

The moisture factor is important for manufacturers of dry mortars or other materials.

Check with your technologists for the required parameters. Usually manufacturers prescribe either up to 0.5% moisture content, or up to 0.2-0.3% moisture content.

For the analysis of moisture, special devices are used - moisture analyzers.

 

  • Packaging
          ⇒

At the "Basis" plant, microcalcite is packed in large bags (big-bag) by 1 ton or in bags of 25-50 kg.

As a rule, it is more economical and more profitable to buy ground marble in MKR (big-bag). But for some types of industries, it is critical to buy microcalcite in bags of 25-50 kg.

 

  • The cost
          ⇒ Explanations are unnecessary here. An important and critical factor is the price of microcalcite. That is why we recommend contacting only manufacturers with their own quarries directly, for example, the products of our Basis plant. Indeed, only in this case you can buy microcalcite in bulk at the best prices.
  • Density
          ⇒ The average density of microcalcite is 2.7 g / cm 2

Microcalcite: fractions

Microcalcite manufacturers try to meet all consumer requirements and offer a wide range of crushed marble fractions. 

The Basis plant produces microcalcite of various fractions from 2 microns to 1000 microns.

You will learn more about the differences between these fractions and the peculiarities of their use  here.

Where to buy microcalcite from the manufacturer

The Bazsey factory is a manufacturer of ground marble. Our advantage is the presence of our own quarry, a marble deposit. We are engaged in the supply of wholesale consignments from 20 tons, most often directly to consumers. Therefore, the Basis plant can sell microcalcite at the best prices.
