Abstract
Disk separators operate on the basis of selective removal of a short fraction grain from a mixture with longer ones, for example, darnel grains and similar impurities from a mixture of wheat grains; or wheat grains from a mixture of wild oat seeds and other longer waste particles. For this purpose, the working bodies of separators— cylinders or disks — are equipped with special cavities, so called “cells”, which location, shape and size correspond to the technological operation. In the flow lines of the grain cleaning workshops of high performance flour mills, predominantly, disk separators, which construction and productivity are well-known from the scientific and technical literature, are used. In recent decades, the improved, so-called small-scale disk separators for wild oat, for example, A9-УТО-6 and some others, have been created and become widely used. Their specialties include, in particular, the lack of interdisciplinary trays in the pre-configured prefabricated input device (i.e., they are characterized by the use of unblocked WUAs). Further improvement of an unblocked WUA is possible on the basis of “The grain mixture cleaning method", which involves the location of cells on the surface of the discs, which ensures that the short particles fall out of them with a compact beam at the same angle, regardless of the distance of the cell relative to the axis of rotation. Therefore, the casting model of the disc should receive a more complex construction, which, unlike the present, mainly manual technology, is expedient to use with modern CNC milling machines.

Summary
