The subject of this thesis is the measurement of flow properties of powder materials. The theoretical part deals with particulate substances in general and describes the basic principles of flow behavior of powder materials. In the theoretical part is a description of the Jenike Shear Tester and Ring Shear Tester. The following section summarizes the Standard Shear Testing Technique. Measurements were carried out on the new apparatus Laboratory of Chemical Engineering. The measurement was selected 5 samples of limestone Omyacarb ® from Omya CZ s.r.o. Individual samples varied in four different particle size distributions and one sample was surface-modified hydrophobic stearic acid. Tests were conducted at 3 levels of the preshear normal stress - 2.5 kPa, 5 kPa and 7.5 kPa. Distribution function of particle size in the material data sheets supplied by the manufacturer were verified using a laser particle size analyzer Sympatec Helos KR purchased in the Materials Research Centre at the Faculty of Chemistry at Brno University of Technology.
