Kinematics Investigations of Bulk Material Motion in Screw Sieve. Part I

The use of rotary screw systems began in the 30s of the XX century as they were part of the emerging military industrial complex. Currently, rotary screw systems are used in a number of sectors of the national economy (in mechanical engineering, in the food industry, in gas and oil production, applicable in such industries as oil refining, chemical industry, agriculture, building industry, construction, etc.). However, the scale of their application is not commensurate with the benefits they provide compared to other types of systems, the functioning of which is based on different technological principles. The paper presents an outlook on the introduction and use of technology and equipment in industry, which will use the original designs of rotary screw bodies with a horizontal arrangement of the rotation axis as working bodies, which will reduce energy costs, improve technical and economic indicators, simplify maintenance and increase productivity. The paper presents the perspective of the use of rotary screw systems in the industry using the example of the cement industry on the example of a design of a furnace with a grate cooler for the clinker production. The proposed design has great scientific and practical significance, which is confirmed by the obtained patents. The presented technology for manufacturing screw bodies and optimizing their design parameters allows outlining and implementing an innovative way to develop cement production. As the results of our research, we not only developed the technology of assembling screw bodies for single and serial production, but also performed work on optimizing their design parameters.

The work purpose is to increase the productivity of bulk material separation by means of engineering process development based on fundamentally new engineering equipment in the form of spiral sieves, the novelty of which is confirmed by six patents for invention of the Russian Federation. In the work there was used a complex method of investigations. Analytical methods allowed offering dependences for the definition of bulk material longitudinal motion speed in spiral sieves. Experimental investigations were carried out in order to confirm analytical dependences. The analytical investigation of bulk material separation into fractions for the purpose of conditional model choice for its description is presented. A mathematical model choice is fulfilled. There is analyzed a model of continuous medium and that of a material particle. A mathematical model is developed to determine a speed of longitudinal motion of bulk material from charging to unloading. There is presented not only a circuit and an experimental plant created in metal version, but the results of experimental investigations of bulk medium motion parameters subject to spiral sieve design peculiarities are shown which presented a coincidence level high enough.

The work purpose is to increase productivity in bulk material separation by means of the development of a test sample of the installation for bulk material separation into fractions. There is considered bulk material motion in a working chamber of the screw screen and the results of experimental investigations of bulk medium movement parameters are presented, depending on design and operation characteristics of screw screens, and also nomograms of dependences of a rate of bulk particle longitudinal movements upon a screw screen diameter, for different values of correction factors, weight of bulk particles, an angular velocity of the screw screen and fill factors. A design of the plant for bulk separation, test data and technical characteristics of the test plant are shown. A novelty is confirmed by six invention patents of the RF. By means of the complex method of investigations there are obtained dependences for definition of a rate of bulk particle longitudinal motion in screw screens, and also a length of working chamber of the screw screen.
