MODERNIZATION OF CORN GRAIN CRUSHER IN THE CONDITIONS OF IT-SYSTEM EQUIPMENT
Abstract
Corn is widely used as a source of starch in the food, pharmaceutical, paper, mining and construction industries. This starch is usually obtained after the cleaning process, and corn germ, fiber and protein are also produced. It is used in the production of biodegradable plastic bags, medicines, paper, corrugated cardboard, detergents, paints, diapers, cosmetics, glue, surfactants and agrochemicals. Corn is the most important grain in the world. After all, in addition to the highest consumption of all grains, corn is also a universal product from which you can get fuel, electricity and household goods. This means that by increasing the volume of corn processing, it is possible to go beyond the agricultural sector and create goods with high added value. Growing corn for grain allows better use of agricultural machinery due to the later dates of sowing and harvesting. Valuable properties of corn cause its consistently high demand on the world market. Corn grain processing is part of the technological lines that are part of cereals. The main equipment that ensures high quality products are impact centrifugal crushers. Analysis of the operation of the impact-centrifugal crusher revealed the possibility of its operation in a wide range of changes in design parameters. The oretical aspects of the dependences of crusher productivity, which basically take its design parameters and modes, include: rotational speed of grinding discs, disc diameter, disc tooth length, thickness, and properties and parameters of grain material. As a result of the conducted researches the possibility of increase of qualitative characteristics of the processed products, and also productivity of the shock-centrifugal crusher is defined. To increase productivity, it is proposed to implement two options. On the one hand to make the rotational speed of the adjustable working body, on the other hand to increase the sizes of diameters of working disks, taking into account a design of the crusher for corn grain, having provided productivity of the crusher. The purpose of this work is to increase the efficiency of the grain crusher, which is part of the preparation of grain for grinding, to ensure the reliability of the machine, its productivity, improve the quality of finished products by implementing automation based on SMART-technology, defined as self-control technology and reporting. This technology provides long-term archiving of the received data that allows the dispatcher to watch work of the corresponding equipment, reacting by means of the IT- service program.
