"NPO Center" offers consumers technological complexes for obtaining ultra-fine modified powders of mineral materials with a particle size predominantly less than 0.01 mm under a manufacturing agreement and is looking for partners interested in a adistribution services agreement.

A technological complex consisting of three main stages has been developed:
- centrifugal impact grinding operating in a cycle with built-in classification;
- high-intensity impact-abrasive grinding;
- highly efficient classification.

The created complex is intended for obtaining ultra-fine modified powders of mineral materials with a particle size predominantly less than 0.01 mm with high homogeneity and whiteness indicators with a virtually complete absence of harmful iron-containing impurities. It can be used to obtain such micropowders as electrocorundum, zeolite, marble, calcite, chalk, cement, talc, graphite, etc.

The cost of the line for obtaining ultrafine modified powders of mineral materials in a complete set (including a classifier of ultrafine powders, an aspiration system and a return system) is 1.9 times lower than the best foreign analogue - Grinding and Classifying System, ECUTEC, NETZSCH Group.

The advantages are:
- in relation to the best domestic samples (indicators) - has no analogues;
- in relation to the best world samples (indicators) - at the level of world analogues;
- import intensity (the share of imports in the cost of a unit of production) is approximately 10-20%.

These technological complexes do not have a negative impact on the environment.

The crushed product has a high specific surface area and physicochemical activity of particles, has a specified narrow granulometric composition.

The reduction of specific energy consumption and the absence of over-crushed classes is ensured by the iterative (continuous) cycle of operation of the grinding complex - "grinding - separation - continuous removal of the finished product from the grinding process".

Compared to other methods of grinding materials, the reduction in energy costs is from 12 to 56%.

Technological complexes for producing ultrafine powders were presented at the 24th International Exhibition of Technologies and Innovations in Industry "TechInnoProm" (Minsk, September 28 - October 1, 2021); the 8th International Scientific and Technical Conference "Innovative Technologies and Equipment. Processing of Mineral Raw Materials" (Minsk, October 5-7, 2021); the 86th Scientific and Technical Conference of the Faculty, Researchers and Postgraduates of the Belarusian State Technological University (Minsk, January 31 - February 12, 2022); the 26th International Exhibition of Machinery and Equipment for Mining, Beneficiation and Transportation of Minerals "MiningWorld Russia" (Moscow, April 24-29, 2022).
