“TECHNOLOGY TO IMPROVE THE TECHNOLOGY OF GYPSUM PRODUCTION AND ENSURE THE OPERATION OF GYPSUM MILLS WITHOUT DETERIORATION”

Аннотация

This article analyzes the problem of the edibility of Raymond- type mill catocs used in the gypsum manufacturing industry. The article will look at the reasons for eating, available solutions and promising areas. Also, the possibilities of producing edible-resistant catoxes using domestic raw materials are analyzed.

The most common Raymond roller mills are used in the gypsum industry- this is a serious problem in which the roller parts of the mills are quickly eaten up by friction work, increasing the cost of the product and reducing the efficiency of production. At the heart of this problem lies the high friction forces between the roller and the material to be crushed. This friction leads to intensive eating of the roller surface, changes in its geometric dimensions and, as a result, to a deterioration in the productivity indicators of the mill. The scientific problem that is envisaged to be solved in this research work is defined as follows: due to the rapid ingestion of roller parts in Raymond roller mills in the Gypsum industry, it consists in the development of materials science and technological solutions to increase the working productivity of the mill and reduce maintenance costs. The essence of the problem lies in the insufficient resistance of existing steel materials to abrasive materials such as plaster. Ordinary Steels, despite their high hardness and mechanical properties, are quickly eaten in conditions of long-term friction. This creates the need for frequent repairs and replacement of spare parts. There is also a technological aspect to the problem. Current Surface reinforcement methods are not sufficient to significantly increase the wear resistance of the roller. While existing methods 78 ACADEMIC RESEARCH IN MODERN SCIENCE International scientific-online conference (such as nitration) only increase hardness in the surface layer, but the softness of the inside of the roller causes it to deform and fail quickly. In addition, optimization of the operating mode of the mill is also important. Current mills, often operating in non-optimal mode, cause overloading and rapid eating of rollers. The loading of the mill, controlling the flow rate and moisture of the material, helps to reduce the ingestion of the rollers. Most of the existing gypsum mills operate on outdated technologies, which leads to low product quality and high production costs. The rapid ingestion of cathocks, one of the main components of gypsum Mills, causes frequent maintenance of equipment, stagnation of production, and an increase in product cost. The catocs of these mills are replaced on average at 5-6 months. Imported catocks, on the other hand, are 2-3 times more expensive than domestic products. This reduces the competitiveness of local gypsum manufacturers and leads to an increase in prices for building materials.Within the framework of the project, the following studies are planned to be carried out to solve these problems: The essence of surface sanding (Poverkhnostnaya zakalka): Surface sanding is the process of hardening the surface layer of a steel object by rapidly heating it to an austenitic state and then rapidly cooling it. This process results in a martensite structure in the surface layer, which provides high hardness and wear resistance. The price of prepared catocks is much cheaper than imported catocks and can easily compete with them even in terms of quality. The service life of the newly manufactured catocks is effectively characterized by being longer than the operating life of the existing Catocks and by being resistant to eating. During the project, a significant increase in the edible resistance of Catocs is achieved. As a result of the optimized technology of thermal processing and the application of new materials, the life of the cathocks is extended by 2-3 times. The surface layer of the roller will have a high hardness, which will increase its wear resistance. As a result of increased wear resistance, the shelf life of the roller increases. Adapted to local conditions, the technology for the production of import substitutes and competitive catocks is created. This technology creates new opportunities in the field of gypsum production. Due to the longer operation of the cathocks, the cost of replacing the spare parts is reduced, which makes the cost of gypsum products cheaper. Within the framework of the project, scientific work is carried out on the basis of this project to attract professors and teachers to scientific research, improve their skills and develop scientific research to at least one PhD degree. In conclusion, this project has a significant impact not only on the achievement of technological achievements, 79 ACADEMIC RESEARCH IN MODERN SCIENCE International scientific-online conference but also on the socio-economic development of our republic.
