The modern development of the national economy is associated with an increase in the processing of non-ferrous and ferrous metals, mining and metallurgical raw materials and construction materials at mining and metallurgical plants.
In the process of preparation of polymer solutions, depending on the type of stirring device and the shape of the vessel, power on the shaft and mixing time, polymer molecules are subjected to mechanical impact and in accordance with the level of this impact can be partially or completely destroyed (mechanodestructured).
One of the most important tasks of the national economic plan for the development of industry is the introduction of high-performance technology of mining and processing of minerals. An essential part of this technology is the movement of minerals in the form of bulk materials, as well as waste enrichment in ferrous and non-ferrous metallurgy.
