Item type:Article, Access status: Open Access , Przegląd metod oceny właściwości geometrycznych odpadowych surowców mineralnych(2007) Szymańska-Czaja, MariaGeometrical properties of grained solid materials describe such parameters as grain size, size distribution curve, grain shape, specific surface, porosity etc. For specifying them in laboratory practice a several different method currently are used. Each method based on different physical phenomena of the material. This cause a diversity of the results, what is inconvenient in introducing to the technological processes applying fine-grained row materials. The paper presents ability assessment of geometrical properties of fine-grain materials investigated in recent years, based on several research results and practical observations unambiguous and multi-conditioned relations between separate geometrical properties.
