Since 1978 till now, the staff of the Department of Applied Mechanics carries out research and development of machines for fine grinding of polymeric, fibrous and moist materials for their utilization and use as raw materials for obtaining new products (VI Kravets, VF Antonenko, MI Ogurtsov). In the process of research, several designs of mills have been developed. One of the latest developments of associate professors V.I. Kravets and VF Antonenko – a versatile three-stage mill with an adjustable degree of crushing opens up wide opportunities for its use in various industries and agriculture. Studies on improving the design of mills and the search for new applications in the industry continue.

Employees of the Department Ass. Glychikov VV and Shishko SV together with an employee of the department of TM and SM as. Trubitsin MN were engaged in theoretical questions of the internal mechanics of the drum mill. Participated in the 3rd international conferences “Theory and practice of the processes of crushing, separating, mixing and sealing materials” (2009-2011), Odessa, where they delivered reports on the development topics. In the process of solving the tasks, scientific contacts are maintained with: prof.Semchenko G.D. (KHPI); prof. Sokur N.I. (Kremenchuk Technical University); prof. Naumenko Yu.V. (Rivne Unitary Enterprise of Water Management); prof. Bilenko LF (St. Petersburg Institute of Mechanobras, Russia).

The new material – fine sand, which is glass microspheres with a diameter of less than 200 microns, having a thickness of a sphere of the order of several microns, is received. Since in the middle of the microsphere is a vacuum, the sand is a good thermal insulating material for mastics, putty, paint and so on. Sandpaper is tested on a paper mill in Dnipropetrovsk, as a heat-insulating material for boiler equipment.

The facility for conducting research on the cavitation process is being developed to optimize energy consumption. With the help of hydrodynamic devices, cavitation enters the liquid flow and is used to intensify physical, chemical and reactive processes.

Head Kravets V.I. and the assistant of the Department Hnatko O.M. Participated in the NATO Environment Conference under the auspices of the Academy of Geopolitical Problems (May 2011, Dnipropetrovsk) with the reports: “Solid waste processing of industrial production by fine milling in a centrifugal mill” and “Electrolyzer for the production of environmentally safe functional water solutions: Study of mass transfer in the ring”. Scientific work was conducted jointly with the University of Manitoba, (Winnipeg, Manitoba, Canada).
