    • A COMPARISON OF THE TENSILE STRENGTH OF PLASTIC PARTS PRODUCED BY A FUSED DEPOSITION MODELING DEVICE 

      Autor: Beniak , Juraj; Križan , Peter; Matúš , Miloš
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      Rapid Prototyping systems are nowadays increasingly used in many areas of industry, not only for producing design models but also for producing parts for final use. We need to know the properties of these parts. When we ...

    • Change of Pressing Chamber Conicalness at Briquetting Process in Briquetting Machine Pressing Chamber 

      Autor: Križan , Peter; Matúš , Miloš; Kers , Jaan; Vukelić , Djordje
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In this paper, we will present the impact of the conical shape of a pressing chamber, an important structural parameter. Besides the known impact of the technological parameters of pressing chambers, it is also very important ...

    • DESIGN THEORY FOR THE PRESSING CHAMBER IN THE SOLID BIOFUEL PRODUCTION PROCESS 

      Autor: Kováčová , Monika; Matúš , Miloš; Križan , Peter; Beniak , Juraj
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The quality of a high-grade solid biofuel depends on many factors, which can be divided into three main groups - material, technological and structural. The main focus of this paper is on observing the influence of structural ...

    • EFFECTS OF INITIAL MOISTURE CONTENT ON THE PRODUCTION AND QUALITY PROPERTIES OF SOLID BIOFUEL 

      Autor: Matúš , Miloš; Križan , Peter; Beniak , Juraj; Šooš , Ľubomír
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
      The moisture content of densified biomass is a limit parameter influencing the quality of the solid biofuel. It influences its calorific value, density, mechanical strength and dimensional stability as well as the production ...

    • Modularity of Pressing Tools for Screw Press Producing Solid Biofuels 

      Autor: Matúš , Miloš; Križan , Peter
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper focuses on the development of the newly-patented structure of a screw briquetting machine for compacting biomass into a solid biofuel. The design of the machine is based on the results of a comprehensive study ...

    • RELATIONSHIP BETWEEN COMPACTING PRESSURE AND CONDITIONS IN PRESSING CHAMBER DURING BIOMASS PRESSING 

      Autor: Križan , Peter; Matúš , Miloš; Beniak , Juraj
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
      In this paper, we will present the impact of the conditions in pressing chambers during the pressing of wooden briquettes. The conditions in pressing chambers can significantly impact the resulting compacting pressure ...

    • STABILIZATION TIME AS AN IMPORTANT PARAMETER AFTER DENSIFICATION OF SOLID BIOFUELS 

      Autor: Križan , Peter; Matúš , Miloš; Beniak , Juraj; Kováčová , Monika
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      The aim of this paper is to present some preliminary results from experimental research on the densification process of solid high-grade biofuels. The findings presented in this paper contribute to an investigation of the ...

    • THE INFLUENCE OF SIZE FRACTION ON THE COMPRESSIBILITY OF PINE SAWDUST AND THE EFFECTIVENESS CRITERION FOR DENSIFICATION 

      Autor: Matúš , Miloš; Križan , Peter; Kováčová , Monika; Beniak , Juraj
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
      Particulate matter from biomass, e.g. wood sawdust, is very diverse. The basic parameter describing the densification process of particulate matter is its compressibility, quantified by the coefficient of compressibility. ...

    • THE OPERATING LOAD OF A DISINTEGRATION MACHINE 

      Autor: Beniak , Juraj; Križan , Peter; Matúš , Miloš; Kováčová , Monika
