Justification of the shape and parameters of the new sorting device for granular materials

The article is devoted to the substantiation of the shape and parameters of a new sorting device for granular materials. It was substantiated the relevance of the new device, which has a great importance for mechanical engineering and agricultural production. A mathematical model for sorting granular materials is proposed. The shape, design parameters and modes of operation of various elements with different: sorting assortment and efficiency indicators were substantiated taking into account the relevance of the device. For this purpose, a new auger sorting device was developed. It was equipped with various automation devices to increase productivity. The satisfactory results were obtained. This sorting device, equipped with an automatic regulator, received a patent from the Copyright Agency of Azerbaijan Republic. The proposed device does not create conditions for pollution of the production area, it has competitive advantages and high rates of technical and economic efficiency.
