Abstract: To design reliable devices for the handling of bulk solids and to characterize bulk solids, the flow properties of these bulk solids have to be known. For their measurement a great number of shear and other testers are available. The chapter gives a review of existing testers and demonstrates which tester should and can be used for which application. Many ideas, methods, and testers exist to measure the flowability of bulk solids. People running those tests seldom are interested in exclusively characterizing the flow properties of the bulk solid in question only. More often they want to use the measured data to design equipment, where bulk solids are stored, transported or otherwise handled, to decide which one out of a number of bulk solids has the best or the worst flowability, to fulfill the requirement of quality control, to model processes with the finite element method or to judge any other process in which the strength or flowability of bulk solids plays an important role. Many testers are available which measure some value of flowability, only some of these shall be mentioned here without claiming completeness. It is beyond the scope of this chapter to describe all testers in detail and to compare them one by one. Instead it tries first to define flow properties. Secondly applications are mentioned. Here the properties, which are needed for design, are described and the testers being able to measure these properties are mentioned. Finally a comparison with regard to application as tried.

01 Jan 2013TL;DR: In this paper, hydrophobic micro-glass particles were obtained by chemical modification with organosilanes and the successful chemical modification process was established using Fourier transform infrared spectroscopy (FTIR) and water drop interaction with the modified particles surfaces.
Abstract: Hydrophobic micro-glass particles were obtained by chemical modification with organosilanes. Particles were treated by peroxymonosulfuric acid to obtain a hydrophilic surface, which was the first step of the modification process. Different silanes were used, each of them with a different functional group, effecting variable degrees of hydrophobicity. The successful chemical modification process was established using Fourier transform infrared spectroscopy (FTIR) and water drop interaction with the modified particles surfaces. The morphology of the modified particles was studied using scanning electron microscope (SEM). The degree of the hydrophobicity was established with static contact angle measurements. The microscopic adhesion and particle contact properties of the comparatively stiff (amorphous) micro-glass beads and the macroscopic powder flow behavior were investigated with ring shear tests and evaluated by constitutive models on physical basis.
