Item type:Article, Access status: Open Access , Energetyczne wskaźniki oceny procesu mielenia rudy miedzi i ich modelowanie(Wydawnictwa AGH, 2005) Trybalski, Kazimierz; Krawczykowski, DamianThe paper concerns the energy consumption problem and copper ores grinding processes evaluation in grinding and classification system of one of KGHM »Polska Miedź« SA ore enrichment plants. The costs analysis of grinding and classification center was conducted, what identified its highest energy consumption. The energetic-technological factors evaluating grinding and classification processes were then proposed and calculated. On their basis the examples of models were constructed, which were regressive ones and neural networks forms, taking into consideration dependencies between process evaluation factors and energetic-technological data of investigated process. The comparison of given models was carried out.Item type:Article, Access status: Open Access , Analiza pracy układu technologicznego mielenia i flotacji z wykorzystaniem modeli blokowych, transmitancyjnych oraz programu Simulink Matlab(2007) Trybalski, Kazimierz; Foszcz, Dariusz; Konieczny, AndrzejThe paper presents one of the mineral raw materials beneficiation technological systems modeling methods. On the basis of laboratory and industrial results concerning grinding and flotation of copper ores, as well obtained beneficiation characteristics and functional dependences, the model of beneficiation system was done by application of block schemes, transmittance models and Simulink Matlab program. Applying the obtained model in the form of calculating schemes, programmed in Simulink Matlab program, the simulating researches of concerned technological scheme were conducted for changeable feed characteristics. Three possible and probable variants of industrial process course were investigated. This concerned both the changes of selected particle size fraction content as well of copper content in individual particle fractions.Item type:Article, Access status: Open Access , Modelowanie przemysłowego procesu mielenia rudy z wykorzystaniem energetycznych wskaźników oceny(2006) Trybalski, Kazimierz; Krawczykowski, DamianThe costs analysis of grinding and classification center in one of KGHM »Polska Miedź« SA ore enrichment plants was conducted in the paper, what identified the highest energy consumption of grinding process.

Identification was achieved by mathematical modeling using the linear regression models of energetic factors to evaluation of the ore preparation process.
