The technology of multi-frequency fractionation of bulk materials and the production line for its implementation









Linked profile in other language
Artsem Makarevich
NPO "Center" offers consumers the technology of multi-frequency fractionation of bulk materials under a commercial agreement with technical assistance, as well as a production line for its implementation under a manufacturing agreement, and is looking for partners to conclude a technical cooperation agreement.
The technology of multi-frequency fractionation of bulk materials is used for sieving bulk materials along boundaries of 0.1 mm or more.

Production lines implementing the technology are used in the chemical industry, in the processing of mineral raw materials, plastics, in the food and mining industries, in the production of building materials, ceramics, metallurgy, woodworking, etc.

Separation of materials in accordance with the proposed technology along the boundary up to 50 microns (which is ten times finer than on classic screens). This prevents clogging and sticking of the screens, resulting in high screening efficiency and the ability to separate materials with high initial moisture. The technology and the production line provide high accuracy of separation of products into fractions compared to traditional screens, high specific screening performance (for fine classes less than 1 mm, the performance is 4 or more times higher), and high sieve durability. When screening at a boundary of 1.5 mm on traditional screens with a grid that are operated for 4-5 days, multi-frequency screens can be operated up to 4 weeks, and their replacement is 5 times faster. The technology and the production line ensure the breakdown of particle agglomerates and low energy consumption for the screening process (to achieve the same performance, the power used is 3 or more times lower).
Advantages and Innovations
The cost of the line is 30-50% lower than that of other manufacturers, which enables domestic consumers to purchase high-quality equipment at a significantly lower price.
