Properties and characteristics of recycled garnet abrasives for AWJ
Martinec, Petr ; Hlaváček, Petr ; Ruppenthalová, Lucie ; Sitek, Libor
The use of recycled garnet abrasive from sludge after cutting materials is a current\nproblem. The behavior of individual garnet abrasives in the AWJ process depends\non the geological origin of the garnets, which also affects all the material\ncharacteristics of the garnet recyclate. The parameters of the BARTON HPX80 and\nGMA 80 abrasive inputs and their recycled products were compared: mineralogical\ntype, apparent density, granularity, grain shape and mineralogical purity,\nmicrohardness data and the degree of damage to the garnet grains. All individual\nparameters of abrasives and their recyclates are reflected in the index of cutting\nefficiency of abrasive. The effect of abrasive material properties on cuttability of\nabrasives is synergistic. The new parameters in the evaluation of abrasives are\nmicro-hardness (brittleness criterion), specific surface and pore size distribution\n(internal grain damage criterion).
Geology of Coal Basins - Czech - Polisch Conference /10./
Ruppenthalová, Lucie
Department of Laboratory Research on Geomaterials of the Institute of Geonics AS CR has organized the Czech - Polish conference about geology of coal basins since 1993. This year the 10th jubilee of conference is held. Traditionally, at the conference meet experts especially from the Czech Republic and Poland, dealing with the development and research of coal deposits, geology of the coal basins, tectonics and coal petrography. However, with new trends in the use of coal, there are also presented the results of research in physical and chemical properties of coal and coal mass, pyrolysis and combustion processes or geosequestration of CO2 into coal seams.
