DEVELOPMENT OF A TECHNOLOGY FOR OBTAINING CYLINDRICAL FILTERS WITH AN ANISOTROPIC STRUCTURE AND HIGH OPERATIONAL PROPERTIES UNDER THE INFLUENCE OF CENTRIFUGAL FORCE

This article investigates the technology of producing cylindrical filters with an anisotropic structure and high operational properties under the influence of centrifugal force. According to the research results, it is established that the method of forming multi-layer filtering elements from metal powders of various sizes has a higher efficiency compared to other traditional methods. Experiments have confirmed that the permeability coefficient, mechanical strength, and efficiency parameter of the filters obtained by the new method increased 2-fold, and the cleaning indicator improved to 1–3 µm. In addition, it is reported that the ability to retain solid particles in the air has increased 3-fold, successfully extending the filter's service life to 8–10 years and reducing the technological process time by 3 hours.
