Hydrostatic generator of non-periodic pressure impulses for testing technical products
The article reviews the possibility of using the hydrostatic generators of oscillators with nonlinear power elements (elastic shells) as part of the structures of various test benches in the field of mechanical tests for vibration strength and vibration resistance, as well as when testing with external and internal pressure. The hydrostatic generator of non-periodic pressure impulses for engineering products testing is a new patented technical solution in the field of testing machines. The ratios of the angular velocities of the shafts, which provides the movement of the operating fluid into the actuator of the test bench in the form of a non-periodic function and with impulses varying in amplitude in a random manner were obtained. It makes a continuous and non-repetitive sequence of pressure impulses and corresponds to the operation of the tested objects in real conditions. The random nature of the amplitudes settings is provided by signals controlled from electric generators through controlled hydraulic valves. The development of a hydrostatic generator with a power element in the form of an elastic shell is represented by a hydromechanical diagram of a generator of non-periodic pressure impulses with corresponding kinematic and dynamic dependencies. In addition, there were developed three hydro-mechanical systems with the use of a new hydrostatic generator for engineering products testing both for mechanical random vibration and for testing the external and internal pressure of engineering objects that operate in such conditions. The result of the research is the expansion of the range of systems and methods for the test processes implementation under random non-periodic force effects on various engineering objects

Vermiculite and vermiculite-based materials have found wide application in many spheres of life: industry, environmental management, fire safety, etc. That's why, the solution of problems related to the improvement of technological processes for heat treating of vermiculite concentrates and conglomerates, especially in the aspect of obtaining high-quality expanded vermiculite, is relevant. The electric modular-trigger furnaces are the foundation for assurance of the resource efficiency of technological processes for expanded vermiculite production. Therefore, the consideration of issues of developing new electric modular-trigger furnaces designs and technological complexes based on them are relevant. The aim of the research is to develop the technological complex for vermiculite processing, study of specified technological processes and evaluation of their effectiveness. The research methods are based on the analysis of information sources in the field of research, the synthesis of constructive and technological solutions, parametric and functional description, experimental studies. Results. The authors have developed a technological complex for processing vermiculite concentrates and conglomerates, taking into account the requirements of energy saving, improving the quality of expanded vermiculite and secondary target products. The modular-trigger furnace was improved. The furnace allows saving up to 15 % of electric power at the same capacity. It was proved that the proposed cooling system provides an increase of the strength of the expanded grains by 19,1 %, an increase to almost 90 % of the release of secondary target products. The main quality indicator - decrease in the poured density of the main target product due to removal of secondary products and inert material - is significantly increased. The authors forecast further works in the aspect of developing a new electric furnace with a movable bottom platform, which has a specific energy capacity for vermiculite heat treating of about 81,6 mJ/m3
Application and production technology of thermal activation products of serpentine minerals from industrial wastes
Relevance. Serpentine minerals, in large quantities contained in mining waste, are part of vermiculite. Singulite is a specimen of serpentine materials as well as expanded vermiculite. They both are applied in environmental technologies: the first one is applied for detoxification of technologically contaminated lands and water bodies, the second one is applied for soil formation. Expanded vermiculite is also widely used in metallurgy, construction and other industries. So, it is necessary to search for development of technologies and equipment to obtain these materials. The aim of the research is to develop a technology for electric thermal activation of the sungutite in power technological units while burning pre-enriched conglomerates obtained from mining wastes, which contain sungulite, vermiculite and olivine-pyroxene rocks. Methods. The research method is based on the improvement of the technology for sungutite conglomerates converting by adding into the technological process the heat-treatment of upgraded electric modular-trigger furnaces. A module with a movable platform with an electric heater is fixed in the design of the furnaces. Results. The results of the research based on upgrading the technology for thermal activation products of serpentine minerals from in dustrial wastes allowed developing the power technological units on the base of upgraded electric modular-trigger furnaces or furnaces with a vibrating bottom platform. This technology makes it possible to compensate partly the costs for heating the useless olivine-pyroxene rock and reduce the power capacity of the technological process. The efficiency of upgrading is proved by deficiency-free obtained materials. As a result, a promising technology for production of thermal activation products of serpentine minerals from industrialwastes is developed

It was observed that the temperatures of the electric heaters and the refractory surface of the firing modules distribute unevenly horizontally: the temperatures decreased significantly from center to periphery. This feature showed a technical solution β the division of the total flow of the expanded vermiculite into local and controlled flows between the thermal zones of the furnace modules taking into account their temperatures. The required time for particles movement in each thermal zone was determined, as well as average local speeds of their movement in the indicated zones were by comparing the thermal capacities of local vermiculate flows. The calculations of local flow rates were carried out and the total productivity of the modernized furnace was determined. The productivity of modernized furnace is 24% higher than the prototype furnace. It is shown that with an increase in productivity but equal to electricity consumption, the specific energy consumption of firing processes decreases by the same 24%. It makes the furnace more perfect and competitive

The improved energy and resource-saving technology, implemented in new technological complexes with preliminary Β«coldΒ» re-preparation, allows returning valuable raw material resources to industrial circulation and obtaining vermiculite and sugulite concentrates from mining waste accumulated in the Kovdor flogopit-vermiculite deposit. Therefore, this work is devoted to the issues of improving the processing of sungulite-vermiculite conglomerates. The aim of the research is to analyze the possibility of improving the technology for producing thermally activated sungulite and expanded vermiculite from mining wastes of the Kovdor phlogopite-vermiculite deposit and increasing its energy efficiency. The object of the research is the technological equipment for processing sungulite-vermiculite conglomerates, which implements energy- and resource-saving technology for producing activated sungulite and vermiculite concentrate. The methods are based on the experimental data and analysis of aerodynamic separation of vermiculite and sungulite from olivine-pyroxene rock and increase of allotment of sungulite in sungulite concentrate. The results prove the aim of the research is achieved. On their basis, it is possible to develop the improved technology for vermiculite producing, including expanded and magnesia-silicate reagent (thermoactivated sungulite) from mining industrial wastes with energy savings of up to 182 kJ/kg, which reduces energy consumption of their processing by 28 % compared to the previous technology. Besides, additional technological operations make it possible to obtain 350 kg of raw vermiculite, 68 kg of pure magnesia-silicate reagent with grain sizes of 2,4...3.5 mm and 158 kg of sungulite concentrate in a thermo-activated form with grains of 1,3...2,4 mm at almost 86 percent concentration. In general, we can conclude that the continuation of work in the field of development and improvement of technologies for processing sungulite-vermiculite conglomerates is promising

ΠΎΠ΄ΠΎΠ².Relevance. Serpentine minerals, in large quantities contained in mining waste, are part of vermiculite. Singulite is a specimen of serpentine materials as well as expanded vermiculite. They both are applied in environmental technologies: the first one is applied for detoxification of technologically contaminated lands and water bodies, the second one is applied for soil formation. Expanded vermiculite is also widely used in metallurgy, construction and other industries. So, it is necessary to search for development of technologies and equipment to obtain these materials. The aim of the research is to develop a technology for electric thermal activation of the sungutite in power technological units while burning pre-enriched conglomerates obtained from mining wastes, which contain sungulite, vermiculite and olivine-pyroxene rocks. Methods. The research method is based on the improvement of the technology for sungutite conglomerates converting by adding into the technological process the heat-treatment of upgraded electric modular-trigger furnaces. A module with a movable platform with an electric heater is fixed in the design of the furnaces. Results. The results of the research based on upgrading the technology for thermal activation products of serpentine minerals from in dustrial wastes allowed developing the power technological units on the base of upgraded electric modular-trigger furnaces or furnaces with a vibrating bottom platform. This technology makes it possible to compensate partly the costs for heating the useless olivine-pyroxene rock and reduce the power capacity of the technological process. The efficiency of upgrading is proved by deficiency-free obtained materials. As a result, a promising technology for production of thermal activation products of serpentine minerals from industrialwastes is developed
Testing a new alternative electric furnace for vermiculite concentrates heat treatment
Relevance. Vermiculite is one of the representatives of geo-resources that are widely used in various industries. The expanded vermiculite is obtained by heat treating of vermiculite ore concentrates in open flame furnaces. Expanded vermiculite, due to its layered-porous structure and high reflectivity, is the base for obtaining many thermo-insulating and refractory materials and products. Vermiculite is a part of building materials, and it is used to protect against radiation. Heat treating of vermiculite ores in flaming furnaces is an energyintensive process; therefore the designs of electric modular-trigger furnaces are being actively developed. These furnaces have not significantly reduced the specific energy intensity of the firing process, that is why the work on creation of electric furnaces is up-to-date. This research is aimed to develop and construct a furnace prototype of a fundamentally new design. The aim of the research is the experimental determination of operational specifications of a furnace model with a vibrating bottom platform which is a separate single-phase firing module during testing. Methods: analysis of information sources in the field of research, synthesis of constructive solutions, physical modeling, parametric and functional description, experimental studies. Results. The authors have developed the alternative electric furnace for firing vermiculite concentrates with a fundamentally new design structure which is a furnace with a vibrating bottom platform. A full-scale physical model of the furnace unit - a single-phase and single-module unit, was developed. Using the above-mentioned physical model the authors carried out the experiments and obtained the empirical data. During the experimental studies, the density of the expanded vermiculite was 90β¦91 kg/m3 and the productivity was 3,56 m3/h. The value of volume energy for various types of vermiculite roasting is 63,7β¦81,6 mJ/m3, which is almost three times less than that of existing open flame furnaces operating on hydrocarbon fuel

It is the platform located at an angle to the horizontal plane. It is relevant to use a horizontal base plate, which excludes spontaneous rolling of material rounded particles and eliminates the possibility of temperature traction occurrence inside the firing space, resulting in cooling furnace heating system as well as fired bulk material. The aim of the research is to study the dynamics of a mobile platform with a base plate and a one-sided elastic element, which provides a strongly presented nonlinear elastic characteristic, and bulk material vibrotransportation over the surface of a horizontal base plate. The object of the research is a mobile base plate of an electric furnace for bulk minerals firing. The methods are based on the development of the design and model of a mobile base plate of an electric furnace for firing bulk minerals. The results of researching the properties of a special elastic element in the furnace mobile base plate allowed obtaining a nonlinear analytical model of its motion, which is characterized by an inclined Β«skeletalΒ» curve of its amplitude-frequency characteristic. The research of the dynamics of an oscillatory system with a one-sided elastic element, providing strong non-linearity, confirmed that the system performs non-symmetrical vibrations with peak vibration acceleration values of 8,32 and 4,79 m/s2 corresponding to the extreme positions of the base plate and differing in 1,74 times. It is shown that when the furnace is installed horizontally, the system sensitivity to fluctuations of excitation frequency, spring stiffness, friction forces and other factors, which change due to the influence of high temperature and external factors, is almost three times reduced. The effect of stable vibrotransportation of bulk material on the horizontal sur- face of the base plate in the thermal field of the furnace is confirmed
