“…All possible combinations of factor values are presented in the matrix. The experiment planning matrix is based on experiment 2 5 , and the effects from the sixth, seventh and eighth factors are mixed with the effects of interaction. Each experience planned by the matrix corresponded to its own design of a batcher mixer.…”

“…These issues cannot be resolved without a timely production upgrade, which is a complex, partial or complete upgrade of the plant's systems and equipment [2; 3]. Modernization as a fundamental problem consists of narrower problems, including not only the development of new types of industrial equipment [4], but also the restoration of parts during repair work [5], the improvement of existing equipment [6], and without damaging the environment [7].…”

The main operations of the process of producing multicomponent mixtures are dosing and mixing operations. The technology of vegetable protein production from sugar beet processing wastes involves the process of dosing and mixing organic acid solution with squeezed juice. The optimal selection of process equipment has an impact on the quality of the obtained product. These processes can be carried out using a liquid batcher mixer. The analysis of the design features of the existing batcher mixers showed their main disadvantages. There are the nonuniformity in the distribution of the additional liquid in the main liquid flow, the additional energy costs for driving the mixing element and the low degree of homogeneity of the finished mixture. An experimental plant for conducting researches of a batcher mixer has been developed. Analysis of the functioning of the used equipment was carried out to determine the main parameters of the liquid dosing and mixing processes. The design diagram of measuring instruments arrangement at the experimental assembly is presented. The purpose of the research in the liquid batcher mixer was to determine the dependencies of qualitative indicators of the obtained mixture on the design parameters. Functions of uniformity of distribution of solution of organic acids in juice on the design parameters of the batcher mixer are shown. Dependencies of coagulation time and the amount of the obtained protein on the content of organic acid solution are presented. Experimental researches made it possible to substantiate the optimal design and technological parameters of the batcher mixer.

“…After analyzing the methods of strengthening the working bodies of agricultural machines [4; 5], it was found that the greatest effect is given by applying strengthening coatings to the front surface of the knife. In addition, there are several methods of coating: plasma surfacing, supersonic sputtering, surfacing by manual electric arc welding, electric spark processing, physical and chemical effects on the part [6][7][8][9].…”

The research is aimed at ensuring the durability of the knives of a feed mixer-distributor with a vertical cutting-chopping and mixing scheme of feed preparation. The analysis of the wear process of the feed mixer knife found that the loss of performance occurs due to the violation of the geometry of the working edge of the knife in the course of mainly abrasive wear. The required level of durability can be achieved by reducing the wear rate. Strengthening the front surface of the knife cutting teeth increases the resource of the working body. Strengthening by electrospark alloying is considered as one of the technological methods. At the same time, an increase in the hardness of the working surface of the edge is achieved, while providing both fatigue and impact strength. When developing the technology, a comparison was made of various materials for forming a coating. The optimal rods are made of steel R5M6 (HSS) and a surfacing electrode T-590. The development of the operating parameters of coating deposition on the BIG-4 installation showed that the oscillation frequency of the electrode and the pulse energy have the greatest influence on the quality of the resulting coating. A microstructural analysis of the coating obtained during alloying in terms of microhardness and porosity has been carried out. For practical use, a technology has been developed and applied for hardening the knives of the feed mixer made of grade 45 carbon steel, which have acquired wear resistance at the level of knives made of 65G manganese steel spring. The results of life tests of hardened working bodies in the production conditions of a company engaged in dairy cattle breeding are presented, which showed an increase in the resource of the feed mixer knives by 67%. Conclusions are made about the expediency of using the developed technology to obtain a hardening coating on the cutting edge of the feed mixer knife.

“…As a result of this action, either structural changes in the reference surface or the formation of a predetermined coating on the surface occur. The conducted analysis of literary sources [18][19][20][21][22] indicates the scientific significance of the problem of studying the physicochemical foundations of surface structure formation in various methods of modifying workpieces from structural metal alloys based on iron, in particular cast iron, and the importance of continuing research in the field of creating strengthening coatings of materials. Therefore, the development of new strengthening technologies to improve the set of performance properties, namely, to increase the wear resistance and durability of cast iron products by modifying their surface is an object requiring further research in the field.…”

The article considers issues of increasing wear resistance of cast iron products by methods of thermochemical treatment of their surface layer. Methods are proposed to solve the problem of wear from cast iron of grade EN-JS1060 due to development of technological processes of strengthening treatment. Alternative versions of strengthening technologies are represented by nitrocarburizing, liquid nitriding and carbonitration. Results of examination of control samples at increasing loads after 200 N before catastrophic wear are given. Comparative analysis of these results showed that samples after carbonitration and liquid nitriding had the greatest bearing capacity (1000 N). Carbonitration is selected as a most preferred option of the surface hardening treatment. Non-poisonous cyanoacid salts are used to realize it.
