INFLUENCE OF A WAY OF CRUSHING ON ACTIVITY OF INGREDIENTS OF CONCRETE MIX
DescriptionThe article presents the results of the researches of the influence of a way of crushing on activity of ingredients of concrete mix. It is shown that sand crushing by method of free kick in a planetary mill of AGO-2 allows not only to raise its specific surface, to receive the demanded particle size distribution, but also to improve quality of a surface of particles by removal, destruction of superficial inactive films. On a new surface of sand excess energy concentrates, the active centers are formed and there is a fixing of germs of new growths of products of hydration of cement in a place of an exit of dislocations to surfaces of crystals of sand that leads to substantial increase of chemical activity and reactionary ability of sand

THE DEFORMATION EFFECT OF VM SLIDER MULTI COMPLEX MACHINE SERIES ON PRECISION MACHINING
DescriptionThe article is devoted to the problems of increasing the economic growth of the Russian Federation, the development of high-tech knowledge-intensive manufacturing industries on the basis of a fundamentally new technological order, new unmanned technologies. The measures to improve the accuracy of manufacturing of complex and large-sized parts. Currently, the technical level of many sectors of the economy is largely determined by the level of production of means of production. The basis of these means is the machine tool industry. On the basis of machine tool development we handle a comprehensive mechanization and automation of production processes in industry, construction, agriculture, transport and other industries. We completed a comprehensive analysis of the errors affecting the manufacturing precision parts. The activities for improving the accuracy of manufacture based on VM 32 multi-machine complex series were proposed. We made the analysis of the cutting forces influence and the cross-sectional shape of the slide on its deformation for various types of processing. We determined the optimal shape of the cross section of the slider to increase stiffness and reduce deformation of the slide in metal cutting

EXPERIMENTAL STUDY OF DIFFUSION OF ENZYMATIC COOKING WHEAT GRANULES
DescriptionThe article describes the process of cooking wheat granules conducted under production conditions of cooking and enzymatic cooking in laboratory conditions. It gives the values of moisture diffusion coefficients and the results of modeling the process of cooking using the equation of non-stationary diffusion method of nets for the implicit scheme. The model takes into account the changes in the moisture concentration of particles in space and time, the temperature change process and avulsion of starch outer layers

Description
The industrial safety on cereal production is currently important due to the severity of the consequences of accidents occurring to them. It should be noted that, despite the considerable efforts of recent years, awareness-raising and supervisory plan towards preventing their occurrence, the lack of attention of organizations operating hazardous production facilities to comply with the relevant standards and requirements allows us to characterize the recent situation in this area quite difficult, as evidenced by statistics. In this article it is clearly illustrated the qualitative and quantitative expression of such an approach in practice. The conceptual framework is disclosed in the light of efforts to carry out industrial safety examination in the conformity assessment of hazardous industrial facilities according to industrial safety requirements in the Russian Federation. The basic methods and technical means used for the prevention of accidents at hazardous production facilities of storage and processing of plant raw materials provide an overview of domestic and foreign producers. The item-description of the system of protection of buildings and facilities of hazardous production facilities is given taking into account the industry specifics. There are specified the key factors meeting modern technical requirements, cost-based position of enterprises, ensuring conditions for safe operation of the storage and processing of plant raw materials
