Abstract
In this work, we consider methods for analytical construction of the profile of rotor blades mixer, as well as mathematical modeling of their work on moving and mixing bulk material on a conveyor to increase process efficiency mixing raw materials and optimizing its operating costs. In addition to increasing the effectiveness of the mixing process and lower operating costs, the goal of implementation the proposed methods is the consciousness of production with the least possible errors that would meet modern technical requirements and be adapted to consumer tasks. In this regard, the aim of this work was to determine rational parameters and geometric characteristics of the profile of the rotor mixer blades contributing to improving the quality of mixing the metallurgical charge transported on a conveyor belt. To achieve the goal by modeling, which is a key method of the fourth concept industrial revolution, using the developed mathematical model analyzed the movement of a particle of material along a conveyor belt with its subsequent interaction with the blades of the working body of the rotary mixer.
Highlights
To obtain metals and alloys of the required chemical composition and mechanical strength, apply various types of necessary raw materials
Analysis of the works [3], [6], [7] related to the development and improvement of various kinds of continuous mixers in the preparation of bulk materials for their further use shows that such equipment should meet current trends in the development of this kind of technology, namely for metallurgical processes, have high performance and at the same time - the degree of mixing of raw materials with negligible operational and capital costs
The purpose of consideration and implementation of such methods is the creation of production with the least number of errors that would ensure the necessary product quality adapted to the needs of consumers. One such mixer in a number technological schemes of metallurgical production can be used mixer continuous with elastic truss elements, the design of which It is rather well described in a number of works [8-12]
Summary
To obtain metals and alloys of the required chemical composition and mechanical strength, apply various types of necessary raw materials. We consider methods for analytical construction of the profile of rotor blades mixer, as well as mathematical modeling of the movement of bulk material along them and conveyor belt, which allows, based on technological requirements, to determine the necessary rational equipment parameters that enhance mixing efficiency components of the metallurgical charge. The purpose of consideration and implementation of such methods is the creation of production with the least number of errors that would ensure the necessary product quality adapted to the needs of consumers One such mixer in a number technological schemes of metallurgical production can be used mixer continuous with elastic truss elements, the design of which It is rather well described in a number of works [8-12]. An improvement on the mixer, made according to such a constructive scheme, constrained by the lack of theoretical research studies the movement of material on the mixer blades horizontally directed action installed directly above conveyor belt transported devices. We consider the methods: analytical construction of the profile of the blades charge rotor mixer rotor materials in order to increase the term operating equipment for the existing technological scheme for the production of sinter and pellets; material movement on the shoulder blade horizontal mixer actions
