The market situation is outlined with regard to screening equipment in Russia. It is noted that, in this market, additional niches emerge that are associated with the introduction of new promising technologies. Examples of such technologies are considered, which are quite close in essence even though originating in such different industries as the manufacture of building materials from crushed stone screenings and the production of mineral fertilizers. In order to fully comply with the ever-increasing requirements of the technologies used in these industries, it is necessary to either fundamentally upgrade the existing vibrating screens or design respective new equipment. The paper contains a substantiation for the application prospects of a vibrating screen with a nonstandard shape and location of the screening surface on the example of the screen developed by Mekhanobr-Tekhnika REC. Two invention patents have already been registered for this screen. The screen implements one of the possible methods of improving the screening performance and efficiency. The paper contains the results of comparative classification tests conducted using the vibrating screen with modified and perforated sieves, which demonstrate the advantages of such modified sieves. It is shown that such a vibrating screen with a modified screening surface has a great potential for application in the new promising technologies.
