The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.2 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00095 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.28 SJR: 0.341 SNIP: 0.536 CiteScore™:: 1.9 H-Index: 57

SINOPSIS

Specific melt types have high viscosity and comparably low surface tension. Therefore, conventional twin-fluid atomization of these viscous melts for powder production often results not in spherical particles but in a great amount of fiber material. In this investigation, viscous mineral melts are atomized in a pilot plant by means of hot gases for spherical particle granulation. Experimental results show that an almost fiber-free product (97% spherical powder) can be obtained. Usually, the atomization process is controlled by the gas pressure only (here before the expansion in the atomizer nozzle). For constant atomization pressure the mass median diameter of the powder yield decreases with increasing atomization gas temperature.
Numerical simulations of the gas flow field in the atomizer vicinity support the analysis of the melt fragmentation process by obtaining the gas temperature distribution and the gas flow conditions within the atomization process. Simulations for different atomizer nozzle designs and several operating conditions have been realized. From the discussion of the experimental results together with the results of the simulations, the relevant shear process between the melt jet and the atomization gas, characterized by the Reynolds number, can be determined as the main driving mechanism of the atomization and spheroidization process.
