Recommendations for the construction of an adaptive vibration mill for the preparation of concentrated feed

At the present stage of development of the processing industry of agro-industrial production is closely connected with the search and implementation of promising technical and technological solutions that provide the possibility of efficient use of energy consumed.

One of the main directions of processing of agricultural products is its grinding. Grinding of grain ingredients is an important operation in the technological process of production of micro-fertilizers for dry feed, herbal flour, premixes, feed, mineral components for animal feed, as well as for the treatment of dependent mineral fertilizers.

Today, the grinding process is carried out mainly by crushing and grinding machines, which are not effective enough, due to significant wear of working bodies (in hammer, rotary crushers), low specific productivity (in ball and jet mills), relatively high power consumption per drive and other factors. A progressive type of grinders are vibration mills, which have high specific productivity, low energy consumption and wide technological capabilities - adjustable grinding tone.

This scientific article provides a constructive scheme of the adaptive vibration mill, in which the vibration field provides the lifting of part of the load(grinding bodies and crushed material) and with the help of a transport-reloading device performs its continuous controlled movement from one grinding chamber to the second, thereby ensuring circulation-spatial movement of the medium in which the grinding process occurs as a result of impact interaction of grinding bodies and crushed material.

The current state of agricultural production requires the development and implementation of innovative equipment, the basis of which is mechatron systems and automated control systems, therefore, the schematic diagram of an adaptive vibration mill for grinding components of concentrated feed given in the floor is a priority for creating vibration mills.

The scientific article provides recommendations for the calculation and design of the main units of the adaptive vibration mill with spatial-circulation movement of the technological medium.
