“…A 3D modeling was proposed as a mechanism for an efficient and convenient way of feeding the mills with balls. In [10], it was found that the broken energy is in relation with the concentration of the balls in a ball drum mill. As a disadvantage of the paper, it can be pointed out that the distribution of balls by size in the drum is not considered.…”

Ensuring the reliable operation of the dust fuel preparation system at thermal power plants (TPP) is a topical issue since it determines the energy strategy of any country that fires coals for thermal energy production. This unit is one of the most energy-intensive units in TPP. Those systems are outdated, poorly automated and high energy-intensive. Furthermore, they must ensure efficient and safe operation of the facility while being environmentally friendly. The current work focuses on the process of grinding coals in ball drum mills for further pulverized combustion. An experimental study was performed in order to determine the main factors (rotational speed of the drum mill, the degree of loading with the grinding balls, and the velocity of the supplied air) that affect the efficiency of the fuel preparation system. The obtained experimental data and performed mathematical modeling resulted in regression equations describing the energy performance of the mill. Three regression equations for mill productivity, power consumed, and specific surface area of the final product were obtained and validated. The study reveals that the lowest specific energy consumption is achieved when the relative rotational speed of the mill is between 0.81 and 0.87; the weighted average diameter of the balls ranges from 33.5 up to 34.5 mm; the load factor of the grinding media ranges from 0.325 up to 0.335, the supplied air velocity is between 0.2 and 0.3 m/s. The proposed methodology allows adjustment of the operating parameters of the grinding process to achieve the lowest energy consumption. The power consumption for the preparation can be reduced up to 5 % for the selected operation mode of the grinding facility.

The constant increase in the consumption of ferrous, non-ferrous, precious and rare metals in the national economy requires an increase in the efficiency of minerals mining and processing. One of the main methods of enrichment used in the technological process of processing various ores is foam flotation. The authors provide a brief description of this process and analysis of various designs of flotation machines. The article is devoted to the modernization of the aeration unit of flotation machines with “RIF” design. It is noted that the design of such machines effectively uses the modular principle of assembly aggregates, which allows you to upgrade individual unit, increasing the efficiency of the machine as a whole. The main part of this unit is an impeller – the most complex and fast – wearing part. The paper analyzes various designs of impellers and their manufacturing technologies. It is noted that in the existing designs of flotation machines, the impellers are made of steel. It is proposed to replace this material with polyurethane, which has become widely used as a structural material due to the emergence of additive technologies in the production of various parts. This material has a relatively low cost and has an increased resistance to wear. The article formulates the main requirements for the most important operations of the technological process of impeller manufacturing. For this purpose, a 3D model of the upgraded impeller design was developed in the SolidWorks 3D computer-aided design system. The authors propose an additive technology for layer-by-layer production of an impeller on a 3D printer using the Ultimaker Cura slicer program. For the manufacture of the proposed design of the impeller made of polyurethane, the production technology was developed by the method of layer-by-layer deposition method of Fused Deposition Modeling (FDM).
