Abstract:

Belt conveyor (BC) transportation systems are considered to be the most effective for handling large volumes of bulk material. With regards to the rules of sustainable development, the improvement of belt conveyor technology is, in many cases, focused on environmental issues, which include the idea of energy usage optimization. The key issue in an energy-efficient transportation system is reducing the value of specific energy consumption (SEC) by increasing conveyor capacity whilst decreasing belt conveyor motion resistance. The main idea of this paper is to conduct an analysis of the modernization of existing belt conveyor transportation systems operated in open-pit lignite mines, in order to achieve relatively small electric energy consumption for a considered transportation task. The first part of the paper investigates the relationship between a conveyor’s SEC and material flow rate for various conveyor design parameters. Then, based on multi-parameter simulations, an analysis of electric energy consumption for a belt conveyor transportation system is carried out. Finally, an energy-saving, environmentally friendly solution is presented.

Abstract:

Conventionally, a series of several individual conveyors is necessary to realise long conveyor lines. This segmentation creates critical transfer points for the transport of goods. The number of transfer points and the overall height can be minimised by direct drives based on magnetic toothed belts and carriers attached to the mat chains. For example, a modular belt conveyor with an overall height of 100 mm and a width of 1 m can reach a length of well over 10 m. The friction between the mat chain and the sliding plane can be reduced by using alternative sliding partners such as a textile or a sliding support made of wood-based materials. These measures increase process and work safety and allow the system to be designed to be energy efficient.

Abstract:

Nowadays, in order to mine the ore economically, it became necessary to increase the tonnage of mined ore, as well as to improve the method of transporting the ore that is to be mined. Belt conveyors are essential equipment for transferring the material from one place to targeted place and conveyor pulleys are the major component of conveyor system. Such kind of conveyor system needs reliable conveyor pulleys. Different type of conveyor pulleys are used throughout the conveyor system as per their function. In this research, the agenda is on modification of present conveyor pulley design by removing the most common causes of catastrophic fatigue failure which are used for high tension application in mining industry. The target during the research is on improvement of end disc design, elimination keyed connection in between shaft and hub by using locking device. The another development is to use of gearless drive technology for drive pulleys. This is obtained by continuous improvement and strategic standardized process to cater the need of mining application. These modified conveyor pulleys are best suitable for high capacity, high tension long distance conveyors used in mining industry.

Abstract:

Exploitation of lignite in continuous surface mines requires removing masses of overburden, which are hauled to a dumpsite. There are some technological arrangements where the overburden is transported several dozen meters down to a spreader operating on a lower located dumping level. Depending on an angle of a declined transportation route, there is a possibility to convert the potential gravitational energy of conveyed down overburden masses into electric energy. To recover the maximum percentage of stored energy, an energy-effective and fully loaded belt conveyor should work in a generator mode. Due to the implementation of such a solution, a lignite continuous surface mine, which is a great electric energy consumer, can obtain the status of an electricity prosumer and reduce its environmental impact, in particular demonstrating significant savings in primary energy consumption. Though lignite surface mining is phasing out in Europe, the recuperative, overburden conveyors for downhill transport match up the targets of sustainable mining, understood as getting the maximum benefits from the exploited natural resources. According to the analyzed case study, an investment into the installation of regenerative inverters for the electric power supply of the declined overburden conveyor would pay off within 3–4 years.

Abstract:

This paper uses the Kelvin-Voigt viscoelastic model to establish the continuous dynamic equations for tail hammer tension belt conveyors. The viscoelastic continuity equations are solved using the generalized coordinate method. We analyze various factors influencing longitudinal vibration of the belt conveyor by simulation and propose a control strategy to limit the vibration. The proposed approach and control strategy were verified by several experimental researches and cases. The proposed approach provides improved accuracy for dynamic design of belt conveyors.

Abstract:

Conveyor belts are widely used in food handling areas, especially in poultry processing plants. Because they are in direct contact with food and it is a requirement of the Brazilian health authority, conveyor belts are required to be continuously cleaned with hot water under pressure. The use of water in this procedure has been questioned based on the hypothesis that water may further disseminate microorganisms but not effectively reduce the organic material on the surface. Moreover, reducing the use of water in processing may contribute to a reduction in costs and emission of effluents. However, no consistent evidence in support of removing water during conveyor belt cleaning has been reported. Therefore, the objective of the present study was to compare the bacterial counts on conveyor belts that were or were not continuously cleaned with hot water under pressure. Superficial samples from conveyor belts (cleaned or not cleaned) were collected at three different times during operation (T1, after the preoperational cleaning [5 a.m.]; T2, after the first work shift [4 p.m.]; and T3, after the second work shift [1:30 a.m.]) in a poultry meat processing facility, and the samples were subjected to mesophilic and enterobacterial counts. For Enterobacteriaceae, no significant differences were observed between the conveyor belts, independent of the time of sampling or the cleaning process. No significant differences were observed between the counts of mesophilic bacteria at the distinct times of sampling on the conveyor belt that had not been subjected to continuous cleaning with water at 45°C. When comparing similar periods of sampling, no significant differences were observed between the mesophilic counts obtained from the conveyor belts that were or were not subjected to continuous cleaning with water at 45°C. Continuous cleaning with water did not significantly reduce microorganism counts, suggesting the possibility of discarding this procedure in chicken processing.

Abstract:

In continuous conveyor systems with circulating traction mechanisms, e.g. chains, the kinematic-dynamic movement behaviour of the traction mechanism is of great importance. Force and vibration analyses can be used to detect overloads and other irregularities in the conveying process. This helps to prevent damage that can lead to a complete failure of the conveyor system. Such analyses are particularly interesting for slide chain conveyors with plastic chains, as these react very sensitively to system overload due to limited thermal and mechanical characteristics as well as often a complex track layout. This article shows how accelerations and tractive forces can be continuously recorded, transmitted and analysed by sensors integrated into the chain links. In addition to the discussion of test results, potential applications of the measuring chain are shown.

Abstract:

Vibrationsförderer sind Stetigförderer, welche Fördergüter durch periodische Schwingbewegungen in gerichtete Bewegungen versetzen. Vibrationsförderer sind in der Handhabungstechnik, der Zuführung von Mikrobauteilen und feinen Pulvern, sowie in der Schüttgut verarbeitenden Schwerindustrie weit verbreitet. In dieser Arbeit erfolgt nach der Betrachtung des Stands der Technik von Vibrationsförderern und den Interpretationsmöglichkeiten der Förderorganbewegung, die Vorstellung und Diskussion weiterer analytischer Berechnungsansätze. Anschließend werden Störprozesse, die während des Guttransportes auf Vibrationsförderern immer wieder beobachtet werden, erstmals klassifiziert und mathematisch beschrieben. Um die DEM-Simulation von Vibrationswendelförderern und linearen Vibrationsförderern unter Verwendung des Gleit-, Wurf- und Haft-Gleitförderprinzips in der Software LIGGGHTS zu ermöglichen, wurde eine Softwareerweiterung entwickelt. Diese Erweiterung umfasst zwei Module, welche die Bewegungen von importierten CAD-Geometrien auf Basis von als Fourierreihen definierten harmonischen Schwingungen höherer Ordnung ermöglichen. Das Befehlsmodul viblin ermöglicht die Definition von translatorischen Schwingungen. Das Modul vibrot ermöglicht die Definition von Rotationsschwingungen um eine raumfeste Achse. Beide Bewegungsmodule ermöglichen die Definition von komplexen Schwingungszuständen der CAD-Geometrien. Untersuchungen der Mikroprozesse innerhalb einer Arbeitsperiode zeigen, für die Förderarten Wurf und Gleiten, alle notwendigen Abschnitte der Kraft- und Geschwindigkeitsverläufe am Fördergut. Die durchgeführten Validierungen stellen die Verwendung der DEM als Simulationswerkzeug in der Vibrationsfördertechnik sicher. Auf der Basis der abschließend durchgeführten Parameterstudien können in Zukunft Kalibrierungsmethoden bezüglich des Verhaltens von Partikeln auf vibrierenden Unterlagen entwickelt werden
Vibratory conveyors are continuous conveyors which move the materials to be conveyed by periodic vibrations of the conveyor chute. Vibrating conveyors are used in handling technology, the supply of micro components and fine powders, as well as in bulk material processing heavy industry. Within this work the state of the art of vibratory conveyors and alternative interpretations of the conveyor movement are introduced. Afterwards further analytical approaches are discussed. Subsequently, interfering processes, which occur during the transport of the materials on vibratory conveyors are classified and mathematically described. To simulate vibrating spiral conveyors and linear vibration conveyors using the sliding, throwing or sticking-glide conveyor principle in the software LIGGGHTS, a software extension was developed. This extension includes two software modules, to define the movements of imported CAD geometries on the basis of as Fourier series defined harmonic oscillations. The viblin command module allows the definition of translatory vibrations. The module vibrot allows the definition of rotational vibrations around a fixed axis. Both motion modules allow the definition of complex vibrational states of the CAD geometries. Investigations of the micro processes within a working period showed all necessary sections of the force and speed progression on the conveyed particles for the conveyor principles of micro throw and slide. The validations constitute the basic function of the DEM as a simulation tool in the vibratory conveyor technology. The final parameter studies can be used to develop calibration methods to describe the motion of particles on vibrating plates

Resumo: Este trabalho propõe um método, via análise convexa, para a solução de problemas de controle ótimo em normas ¿H IND. 2¿ e ¿H IND infinito¿ utilizando-se realimentação estática de estados, de saída e dinâmica de saída. Em cada um dos casos, uma transformação não linear parametriza o conjunto de todos os ganhos estabilizantes através ou de um conjunto convexo (no caso de realimentação de estados) ou da intersecção entre o conjunto convexo anterior e um conjunto definido por uma função real. Em seguida, condições necessárias e suficientes para a existência do ganho procurado são propostas, o que permite a solução dos problemas ótimos ¿H IND. 2¿ e ¿H IND. infinito¿. Os problemas de observador de estados ¿H IND. 2¿ e ¿H IND. infinito¿ são tratados como duais ao problema de regulador. Os problemas de regulação dinâmica de saída são expostos como extensões das soluções anteriores. A principal característica da formulação proposta é sua versatilidade, permitindo que diversos problemas venham a ser considerados, como os problemas de custo garantido ¿H IND. 2¿ e ¿H IND. infinito¿, no caso de sistemas incertos pertencentes a domínios convexos poliedrais, os problemas de descentralização de ganho e os problemas de falhas de atuadores/sensores. Dois algoritmos são propostos para a solução dos problemas, ambos baseados no método de planos de corte
Abstract: This thesis proposes a convex programming approach for the optimal solution of H IND. 2 and H IND. INFINITE control problems by static state feedback, static output feedback and dynamic output feedback. In each case, a nonlinear transformation parametrizes the set of all stabilizing control gains either by a convex set (in the case of state feedback) or by a intersection between a convex set and a set defined by a real-valued function. Necessary and suflicient conditions are derived for the existence of the gain, which allows the solution of the H IND. 2 and H IND. INFINITO optimal control problems. The observer problem cases are solved by duality and the dynamic feedback cases follows directly from the state regulator control problem. The proposed formulation main characteristic is the versatility. It allows to deal with uncertain systems in convex bounded polyhedral domains, the decentralization problems and the failure actuator/sensor problems. Two algorithms are proposed for solving the aforementioned problems, both based on the cutting-plane methods

Includes bibliographical references (page 38).
This research attempted to assess the feasibility of using screw conveyors as a means of continuously rearing black soldier fly larvae. Farming of the black soldier fly (BSF) has gained popularity in recent years as means to supply protein for animal feed and recycle food waste. However current methods for BSF farming are labor intensive and costly. This is due partly from the batch system in which BSFs are grown. It is also a factor of space inefficiency, as BSF larvae can only live in the first 7-10 cm of the substrate they are grown in due to oxygen depletion. Screw conveyors in theory could solve both these problems by allowing for continuous production and mixing which could aerate the substrate preventing oxygen depletion. In order to test the feasibility of using screw conveyors an analysis was done to predicted energy cost. Based on the calculations done in this work energy cost would be trivial, on the order of 0.01 US dollars or less per pound of dry weight BSF larvae. Physical experiments were also done on the effectiveness of mixing in aerating the substrate and allowing BSF larvae to live deeper. This involved filling a tube with substrate and BSF larvae to various depth between 15 and 45 cm and measuring oxygen levels at the bottom depth. The tube was also flipped to simulate mixing. While there is a high level of uncertainty, the results in general indicate oxygen was depleted in the substrate on the order of 5-10 minutes for depths bellow 15 cm. This does not support the feasibility of using screw conveyors for BSF farming as the conveyor would have to be running almost constantly to prevent the development of anaerobic conditions. However many factors in this research where high conservative and the development of anaerobic zones in BSF substrate and the effects of mixing warrant further research.

Abstract:

Gas-solid two-phase flows are widely seen in many industrial processes. A good example of these is the pneumatically conveyed pulverised fuel (coal/biomass) flow in the power generation industry. In order to achieve efficient operation of a power plant it is desirable to monitor the physical characteristics of fuel particles. As one of the most important characteristics, particle size distribution should be monitored to increase combustion efficiency, to minimise pollutant emissions, and to reduce milling cost. This thesis describes the design, implementation and experimental evaluation of two prototype instrumentation systems for in-line, continuous size measurement of pneumatically conveyed particles. A review of methodologies and techno logies for the in-line measurement of particle size distribution is given, together with the discussions of existing problems and technical requirements in their applications. Based on this review, a particle impact sensing system using a piezoelectric film sensor incorporating particle impact modelling and signal processing algorithms is proposed. Experimental results obtained on a laboratory test rig demonstrate that the system is capable of measuring particle size distribution and can be used to provide an assessment of flow characteristics wider various flow conditions. The system also demonstrates that this technology is practical and operational on a full-scale power plant. Additionally, the thesis also reports the latest development in particle imaging technology. A novel particle imaging system using multi-wavelength illumination sources is designed and implemented. Experimental results on a laboratory-scale rig show that the multi-wavelength design has increased the coverage of flow field and improved the system repeatability compared to the single-wavelength system. Finally, the particle impact sensing system and particle imaging system have their own advantages and limitations and both require further research. The work reported in this thesis offers a foundation for future in-line measurement of particle size distribution and demonstrates the potential of the proposed techniques.

Abstract:

Intelligent process control technology in various manufacturing industries is important. Vision-based non-magnetic object detection on moving conveyor in the steel industry will play a vital role for intelligent processes and raw material handling. This chapter presents an approach for a vision-based system that performs the detection of non-magnetic objects on raw material moving conveyor in a secondary steel-making industry. At single camera level, a vision-based differential algorithm is applied to recognize an object. Image pixels-based differential techniques, optical flow, and motion-based segmentations are used for traffic parameters extraction; the proposed approach extends those futures into industrial applications. The authors implement a smart control system, since they can save the energy and control unnecessary breakdowns in a robust manner. The technique developed for non-magnetic object detection has a single static background. Establishing background and background subtraction from continuous video input frames forms the basis. Detection of non-magnetic materials, which are moving with raw materials, and taking immediate action at the same stage as the material handling system will avoid the breakdowns or power wastage. The authors achieve accuracy up to 95% with the computational time of not more than 1.5 seconds for complete system execution.

Abstract:

This paper looks at a two new conveyor technologies that offer the opportunities for significant improvement in the handling of coal in power plants, and in bulk transportation facilities, and other coal-handling operations. This first technology is “flow-engineered” chutes. Based on material testing and flow studies, these chutes allow the development of transfer chute systems that provide better control, continuous coal flow at higher capacities, and dramatic reductions in material spillage and the release of airborne dust. By regulating the coal flow path of movement, these engineered chutes improve the load placement on the belt, eliminate chute blockages, reduce safety hazards, and minimize maintenance costs. The second leading edge system is air-supported conveyors. Air supported conveyors are now seeing increasing acceptance in coal handling applications in power plants. This is due to the advantages they offer to coal-handling, including high efficiency and low maintenance. This technology also provides a reduction in the release of coal dust, as the carrying side of the conveyor is completely enclosed. This paper will discuss recent installations of these systems in coal handling facilities. In particular, it will feature the engineering and installation of flow-engineered chute systems at AmerenUE’s Meramec and Rush Island Electric Generating Stations, to improve conveyor system performance, while reducing dust as much as 98%. He will also discuss recent application of air-supported conveyor systems in coal handling systems, and discuss the benefits of the application of conveyors combining both “leading edge” systems.

Abstract:

To address issues associated with the recently updated OSHA Instruction on combustible dust hazards, this presentation will explore an innovative concept of conveyor design. The author will also examine two “leading edge” conveyor technologies and review recent projects that employed these two technologies. This presentation will first address concerns associated with the OSHA Instruction on combustible dust hazards by exploring the architecture concept for conveyor design and the new dust accumulation resistant conveyor structure. This pioneering approach to conveyor design focuses on prevention of fugitive dust accumulation and ease of maintenance. The next of these advanced technologies is “engineered-flow” chutes. Designed from material testing and flow studies, these transfer chute systems provide better material control, continuous flow at higher capacities, and dramatic reductions in material spillage and the release of airborne dust. By regulating the path of material movement, these engineered chutes improve the load placement on the belt, eliminate chute blockages, reduce safety hazards, and minimize maintenance costs. A third leading edge conveying system is air-supported belt conveyors. Rather than using rollers, these leading edge systems use a film of air rising from a troughed pan to support the belt and cargo. These totally enclosed conveyors offer a number of benefits, including improved tracking, improved control of dust and spillage, and reduced friction and power consumption. In this presentation, the author will present “project profiles” of recent installations of these systems. The author will look at the reasons these systems were selected and report on the lessons learned from system engineering, installation, and operation. These projects will include systems handling Powder River Basin (PRB) coal in mines and power plants.

Abstract:

Occupational noise-induced hearing loss continues to be one of the most pervasive health problems in the mining industry, despite over 25 years of regulation. One of the loudest pieces of equipment used in underground mining is the continuous mining machine. Noise sample data collected by the Mine Safety and Health Administration indicate that 42% of noise overexposures between 2000 and 2005 involved continuous mining machine operators. Previously conducted field and laboratory tests have determined that the continuous mining machine conveyor system is a dominant noise source. Loud impacts occur as the conveyor chain flight bars, used to move the mined aggregate, traverse their path from the top to the underside of the conveyor deck. Various noise control treatments have been applied to abate noise caused by the conveyor system. A durable polyurethane coating has been developed for the conveyor flight bars, resulting in a time-weighted average reduction of 3 dB(A) for an eight-hour work shift. In an attempt to further reduce continuous mining machine operator overexposures, a similar urethane coating has been applied to the tail roller component of the conveyor system. Laboratory results showed a 2 dB(A) reduction in sound power levels, but the component failed during underground durability testing. An outer steel sleeve has been added to the urethane coating of the tail roller to enhance wear resistance during mining. The urethane jacketed tail roller is the latest effort, combined with previous noise treatments, to bring the continuous mining machine into compliance with federal noise regulations.

Abstract:

The reliability of conveyor systems is the main requirement because of the high consequential costs in case of malfunction of intralogistic systems. In order to ensure this claim manufacturers react with robust modules of which these systems are composed. The consequence of this is that the design of intralogistic systems is not adapted to customer requirements. To develop a basis on which continuous conveyors can be designed, three Response Surface Models based on measurands have been worked out. With the help of a statistical software the response values of the models have been optimised.

Abstract:

Noise Induced Hearing Loss is the most common occupational disease in the U.S. and of paramount importance in the mining industry. According to data for 2006 from the Mine Safety and Health Administration (MSHA), Continuous Miner operators accounted for 30.2% of underground mining equipment operators with noise doses exceeding the Permissible Exposure Limit (PEL). This figure becomes more significant considering that 49% of the 2006 national underground coal production was extracted using continuous mining methods. Thus, there is a clear need to reduce the sound radiated by Continuous Mining Machines. The first step towards efficient noise control of a Continuous Mining Machine requires identification of the various noise sources under controlled operating conditions. To this end, a 42-microphone phased array was used in conjunction with 4 reference microphones to sample the acoustic field of a machine in the Hemi-anechoic chamber of the Pittsburgh Research Laboratory. These data were processed using a frequency-domain beamforming algorithm to obtain acoustic maps of 5 sides of the machine. The focus of the test was on the conveyor noise since previous studies showed that operation of the conveyor is the most important contributor to the sound radiated by the machine. From the acoustic maps, the following potential areas for noise control were identified, and included: chain-tail-roller interaction, chain flight tip-side board interaction, and chain-upper deck interaction.

Abstract:

The article investigates functional techniques of extralinguistic expression in multimedia texts; the effectiveness of figurative expressions as a reaction to modern events in Ukraine and their influence on the formation of public opinion is shown. Publications of journalists, broadcasts of media resonators, experts, public figures, politicians, readers are analyzed. The language of the media plays a key role in shaping the worldview of the young political elite in the first place. The essence of each statement is a focused thought that reacts to events in the world or in one’s own country. The most popular platform for mass information and social interaction is, first of all, network journalism, which is characterized by mobility and unlimited time and space. Authors have complete freedom to express their views in direct language, including their own word formation. Phonetic, lexical, phraseological and stylistic means of speech create expression of the text. A figurative word, a good aphorism or proverb, a paraphrased expression, etc. enhance the effectiveness of a multimedia text. This is especially important for headlines that simultaneously inform and influence the views of millions of readers. Given the wide range of issues raised by the Internet as a medium, research in this area is interdisciplinary. The science of information, combining language and social communication, is at the forefront of global interactions. The Internet is an effective source of knowledge and a forum for free thought. Nonlinear texts (hypertexts) – «branching texts or texts that perform actions on request», multimedia texts change the principles of information collection, storage and dissemination, involving billions of readers in the discussion of global issues. Mastering the word is not an easy task if the author of the publication is not well-read, is not deep in the topic, does not know the psychology of the audience for which he writes. Therefore, the study of media broadcasting is an important component of the professional training of future journalists. The functions of the language of the media require the authors to make the right statements and convincing arguments in the text. Journalism education is not only knowledge of imperative and dispositive norms, but also apodictic ones. In practice, this means that there are rules in media creativity that are based on logical necessity. Apodicticity is the first sign of impressive language on the platform of print or electronic media. Social expression is a combination of creative abilities and linguistic competencies that a journalist realizes in his activity. Creative self-expression is realized in a set of many important factors in the media: the choice of topic, convincing arguments, logical presentation of ideas and deep philological education. Linguistic art, in contrast to painting, music, sculpture, accumulates all visual, auditory, tactile and empathic sensations in a universal sign – the word. The choice of the word for the reproduction of sensory and semantic meanings, its competent use in the appropriate context distinguishes the journalist-intellectual from other participants in forums, round tables, analytical or entertainment programs. Expressive speech in the media is a product of the intellect (ability to think) of all those who write on socio-political or economic topics. In the same plane with him – intelligence (awareness, prudence), the first sign of which (according to Ivan Ogienko) is a good knowledge of the language. Intellectual language is an important means of organizing a journalistic text. It, on the one hand, logically conveys the author’s thoughts, and on the other – encourages the reader to reflect and comprehend what is read. The richness of language is accumulated through continuous self-education and interesting communication. Studies of social expression as an important factor influencing the formation of public consciousness should open up new facets of rational and emotional media broadcasting; to trace physical and psychological reactions to communicative mimicry in the media. Speech mimicry as one of the methods of disguise is increasingly becoming a dangerous factor in manipulating the media. Mimicry is an unprincipled adaptation to the surrounding social conditions; one of the most famous examples of an animal characterized by mimicry (change of protective color and shape) is a chameleon. In a figurative sense, chameleons are called adaptive journalists. Observations show that mimicry in politics is to some extent a kind of game that, like every game, is always conditional and artificial.
