The object of research is the design of a ball mill for grinding dry materials, the subject of research is the efficiency of grinding material based on improving the design of a ball mill. One of the important problems for ball mills is the problem of reducing the efficiency of grinding material. The degree of grinding of materials in ball mills ensures the quality of the product. That is why this work is aimed at choosing a way to improve the design of the ball mill in order to increase the efficiency of grinding material. This will provide a better process of grinding the material in the ball mill. The study used the analysis of the features of the ball mill designs, literature and patent review of existing ways to improve the designs of the ball mill to improve the efficiency of grinding material. As a result of the literature-patent review the method of improving the ball mill based on the prototype, which has a rotating drum with longitudinal partitions and grinding bodies, longitudinal partitions are located diametrically at right angles with windows alternating on both sides from the intersection. It is shown that the proposed method of improving the design of the ball mill will increase the efficiency of grinding dry materials. This is due to the fact that when moving the grinding bodies and the material on the partitions there is a collision of flows, and this will increase the productivity of the ball mill. Also at the same time there will be a decrease in the moment of resistance to rotation of a drum of a ball mill that will provide economy of the electric power for its work. In comparison with the known designs of the ball mill, the execution of diametrical partitions at right angles with prisms in the drum of the mill all the grinding bodies, and the material is moved along the partition, then half of the drum. This will increase the efficiency of grinding the material in the improved design of the ball mill.

“…Since quartz sands with fractions ≤1 mm are not regulated for the construction industry, their storage reserves increase every year, as a result of which foci for dust formation appear, weathering of raw materials occur, dust storms form, and the ecological situation worsens [25,26]. Creation of effective granular aggregates with sufficient physical and mechanical properties based on small quartz sands can reduce the consumption of energy resources during production and reduce the consumption of expensive binders, thereby helping to reduce the negative technogenic burden on the environment in the production of Portland cement [27,28].…”

It is necessary to solve the ecological problems of regions where there is large-tonnage storage of various finely dispersed materials, including technogenic ones. This article presents the results of an investigation into the possible use of substandard dispersed quartz sands to obtain effective granular aggregates, with the purpose of putting them to use in mortars and concrete. The study used standard and original experimental research methods related to the analysis and preparation of raw materials, technological tests, and the study of the properties of finished composites. Investigations were carried out to obtain composite binders in the component composition of which the use of different ratios of Portland cement and substandard quartz sands prepared in a vortex jet mill was envisaged. It was found that the obtained composite binders had high physical and mechanical characteristics, which was due to the high specific surface area and hydration activity. On the basis of composite binders and finely dispersed quartz sands (fineness from ≤0.16 mm to 1 mm), the granulation of mixtures of 36 types of component compositions was performed. The developed compositions of granular aggregates (GAs) showed the possibility of obtaining them with sufficiently high strength values in cement stone. The studies carried out make it possible to recommend finely dispersed substandard and technogenic materials for the production of GAs, which would ensure the economy of binding materials as well as contribute to the reuse of large-tonnage waste of ferrous and nonferrous metallurgy and the chemical and mining industries.
