IMPROVING THE EFFICIENCY OF LIME PRODUCTION PROCESS USING FLOCCULANT

Abstract: Inseparable element of the lime production process is pipeline transport of hydromixture which arises from rinsing of stones. Such hydromixture is a finely-granular solid phase and the water that serves as a carrier of the solid phase. At the end of the transporting process the water is recovered in order to recycle it for re-circulation, and the solid phase is deposited in dumps or in the sludge tanks. Hydromixture clarification process through the process of sedimentation, is difficult due to the large amount of solid particles with a diameter less than 2 mm. In order to improve the efficiency of sedimentation process we added polymer additives called flocculants. They allow the formation of flocs by binding together fine particles into larger agglomerates, which are under the influence of gravity and fall intensively to the bottom of settler tank.

Keywords: hydraulic mixtures pumps, experimental studies, flocculant, efficient use of water

THE EFFECT OF HIGH SOLIDS CONCENTRATION ON THE RHEOLOGY OF LIMESTONE SLURRY

Abstract: The paper deals with solid-liquid limestone slurry with a high solids concentration, which appears widely in a mining and civil engineering industries. Experiments performed in the paper deal with influence of solids concentration on the shear stress. Solids concentration various from 20% wt. to 35% wt. which is most suitable to industry. The main objective of the paper is to determine the flow curves for high solids concentration of slurry at limestone factory and to fit the proper rheological model. The paper proves that most suitable model which fits measured dependence of shear rate on the shear stress is the Herschel-Bulkley rheological model. The exponential increase of shear stress and plastic viscosity with increasing the solids concentration is demonstrated for high solids concentration of limestone slurry.

MEASUREMENT SYSTEM ANALYSIS OF ATTRIBUTE OR CONTINUOUS DATA, AS A ONE OF THE FIRST STEPS IN LEAN SIX SIGMA PROJECTS

Abstract: Measurement System Analysis is a part of “Measure” phase, which is a structured project management approach. This approach consist of the following steps: Define, Measure, Analyze, Improve, Control – “DMAIC” and is a path to resolve production problems based on Lean Six Sigma methodology. This method has been presented by using of computer aided statistical software – Minitab – which is a most common statistical software, used by Green or Black Belts. As a Master Black Belt I faced to the problem of lack an appropriate explanation of using it by the Belts – which contributed by implementation of a proper training program. Measurement system analysis in this program, is divided by Attribute Agreement Analysis, which is analysis of attribute data, and Gage R&R – analysis for continuous data. Therefore it is very important to understand differences between attribute and continuous date and their main metrics. Understanding data types, allowed to explain components of measurement errors. This base knowledge is a foundation of measurement system analysis and going further – base knowledge of each Green or Black Belt.

MOTYVATION AND CONTROL IN TECHNICAL SYSTEMS

Abstract: The study presents issues related to the motivation of human action and its shaping. The issues are presented from the point of view of psychology, sociology, management science and cybernetics. It was found that in the application of appropriate stimuli may affect motivation to change and consequently the change in quality of performance. The common denominator of these areas of study is the conclusion that the motivation may be the result of the conditions of information or energy. Maslow, human motivations, addicted from needs. He introduced the so-called pyramid of needs, from which it follows that the greatest impact of human motivations are the needs of an energetistic nature. But the Herzberg in his two-factor theory of motivation found that motivations are the result of exposure to man, so-call motivators such as stimuli (incentives) of the informative nature. At the same time he provided the conditions which made the effectiveness of these motivators. Mazur introduced the man as an autonomous system and describe the processes that determine the motivation of action. He said that the man, as the system must be able both to retrieve from environment as well to place on in to the environment, the information and energy. This means that the motives of human actions can have only informative and energetistic character, what largely corresponds with the results of sociological research. Kossecki linked motivations of human activities with distinctive social norms and depends of the human norm type, he found that motivations can be informative, energetistic, or mixed. To similar conclusions is reaching when it is depending the type of motivation of man's relation to the basic categories of social existence, given by Koneczny. Using the principles of transmission of information it has been shown that the efficiency of the control depends on the motivation. People with the energetistic motivation are more likely susceptible to control. In the discussion are presented examples of control in technical systems, typical for the problems presented in the work.

CONCEPT OF A DECISION SUPPORT SYSTEM TO SELACT THE OPITMAL CCT SOLUTION FOR A CHOSEN LOCATION IN SILESIA REGION

Abstract: Decision Support Systems (DSS) are computer-based tools which can assist managers of different disciplines, local governments, investors and other stakeholders to simulate, evaluate, and/or optimize management alternatives. This study aims to elaborate and develop a concept design of a DSS and explore the possibilities which it offers in selecting the most optimal Clean Coal Technology for a given location in the Upper Silesian Coal Basin. The implementation of CCT is a very complex process and is characterized by the interaction of many factors such as: economic, environmental, legal and social therefore, as a consequence the decision-making becomes intricate. The study consisted and relied on the draw-up structure, the determination of fundamental components of the DSS and the generation of recommendation reports. Furthermore, the identification of the DSS user’s needs was carried out along with the classification of the main groups of users, which have a direct impact on the implementation processes of the CCT in the Upper Silesian Coal Basin.

Keywords: Decision Support Systems, Clean Coal Technologies, decision-making, technology implementation.
