Talc is widely distributed all over the world, but its storage capacity is small. The white talc is even more rare. White talc is mostly produced in China, India, Australia, France, Italy, Korea and other countries, of which China and India have a larger production of talc.

But in many cases, the talc output on the data is often higher than the actual output. What is the cause of this problem? Some of the chlorite will be counted as the talcum powder. In addition, there will be a part of the talc belongs to low-grade talc.

Talc powder is widely used in cosmetics and daily necessities. For example, talcum powder is used as the main ingredient in baby powder. Talc powder is closely related to our lives, so its safety has received great attention. It is important to note that in the natural environment some talc and asbestos are associated or symbiotic. Asbestos are easily mixed with some of the talcum powder used in some industrial fields, and asbestos is a known carcinogen. Do not worry. The talc powder used in our life has been through rigorous testing.

Next let’s look at the production and processing technology of talc.

The talc powder is mainly processed by dry method. The equipment used before mainly includes Raymond mill, impact mill and airflow mill. But with the development of ultra-fine grinding, this kind of machine has been more and more applied to talc processing.

Ultra-fine grinding mill, also be called micro powder grinding mill, has won an increasingly larger market in recent years. And why?

To be honest, with the development of modern industry, the purity, whiteness and fineness of talcum powder have met higher and higher requirements. But talcum powder as inorganic filler has great difference in chemical structure and physical form with organic polymer and molecular material. The lack of affinity of talcum powder makes it a problem of uneven mixing and weak adhesion between the polymer and the polymer, thus reducing the mechanical properties of the products. Therefore, the surface modification of talc must be carried out.

The ultra-fine talc processing plant in our company not only remains good reputation in the talc powder fineness processing, but also be popular for its auxiliary equipment. Powder surface coating machine is one of the auxiliary machines in the whole ultra-fine stone (talc) processing plant. The powder surface coating machine with unique chamber design is applicable to the modification of many materials. Of course, talc powder is definitely included here.
