Company Profile

The result of more than 30 years of experience of its founders and leading experts - a unique grinding technology that enables the production of various grades of finely dispersed talc powder of the highest quality.

About us

Our young company was established with one goal in mind - to build a plant using the latest technology that is unparalleled in the world and to produce a high-quality, competitively priced product.

Finegri, established in 2021, is a company for the production of finely dispersed industrial minerals, particularly talc. The technology has been patented, has undergone numerous industrial approbations, and has been successfully implemented in many enterprises all over the world.

The process know-how applied at our production facilities allows delivering the end product having an exclusive quality, with the highest health, safety and environmental standards met.

Finegri’s personnel comprises high-skilled specialists in various areas: each one of them speaks several languages and has a long track record of international projects aimed at developing production enterprises, introducing innovations into business and production processes, and other related areas.

Finegri’s personnel is a team of specialists having various profiles and united by innovative ideas. We both manage our own unique manufacturing processes, and use our competences to implement the ideas of our customers by offering turnkey solutions.

For us, each customer’s desire is a challenge and an opportunity to make favourable changes in our productions processes and to become more flexible. We listen to and hear our customers, while our lead specialists implement innovations and create additional opportunities for everyone cooperating with us.

We generate innovations: Finegri is a synonym to “innovation”.

Funding for scientific activities and construction of plants for the production of fine-dispersed materials began over 10 years ago.

Since then, nearly 20 plants and production lines have been built across Europe, East Asia, and North America.

The first patents were obtained to confirm the exceptional capabilities of the developed methods for ultrafine grinding of materials.

What is Talc?

Talc is a natural mineral and a subsurface rock, which this mineral forms. It is also industrial fine-grained raw materials used in different industries, mainly as a filler.

The approximate talc chemical formula is Mg3Si4O10(OH)2. The formula can vary subject to specific chemical impurities.

Magnesium in the mineral may be replaced by other elements: ferrum, calcium, nickel; aluminum, chromium and manganese additions may also be present.

Depending on the composition and additions, the rock may have reddish brown colour; it may be white, greenish, bluish, or grayish with rose, golden and yellow tones. Its formula may vary depending on the specific chemical additions.

Geology

Talc is quite widespread in the wild. Subject to its structure and impurities (nickel, manganese, chrome, iron and aluminum), there are the following types of talc as a mineral:

Agalite. Has acicular structure. The crystal needle fibers are arranged in almost parallel position, in one direction.
Minnesotaite. Characterized of iron content (replacing magnesium), which embrowns it.
Steatite. Characterized of compact structure. Also called soap stone or soap rock.
Willemseite. Characterized of bluish or greenish tint due to nickel content. More than half of magnesium in the mineral is replaced with nickel.
Noble talc. High-density semi-transparent stone. Susceptible to processing.
Soapstone (talc-chlorite).

Physical properties

Talc has the following properties:

Odorless.
Water-insoluble.
Is inert to acids, works to the tank bottom.
Good adsorbing material.
Absorbs odors well.
Low thermal conductivity.
Low hardness of 1 on the Mohs hardness scale.
Low density (2.75 kg/m³).
Fire-resistant.
Transforms into a very hard material when strongly heated (800-900°C).
Good dispersive capacity.
Fine-grained talc powder and water form indiscernible substance.

Sustainability

The entire initial ore feed and pre-grinding system is equipped with an air aspiration system, which enables complete air purification in the industrial process.

Finegri’s gridding system does not require any additional air intake. The system only uses ambient air fed into the pre-grinded product from the atmosphere.

Thereafter, fine grinding takes place, and the end product goes to the silo group equipped with the aspiration and filtration system for complete air purification in the fine grinding area.

In the packing section, silos containing the end product are connected to packaging machines that automatically package the product into multi-layer perforated paper bags with a polyethylene insert and polypropylene big bags. The entire process line is secured against emissions by the aspiration system. Next, bags are conveyed to the palletizer, where they are stacked on pallets, and the pallets are automatically wrapped with a polyethylene film.

The process line management is fully automated, and the key control parameters are displayed on the central console and doubled by the central computer, which protects the entire system from the “human factor”, automatically records the key figures, analyses them, and (where necessary) adjusts the parameters.

The quality laboratory ensures quick and objective control of the feedstock (ore) and end product (powder).
