“…References mention more methods for the fabrication of the powders having spherical particles or granulates [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In the author's opinion, the methods of producing this type of powders can be classified, according to the nature of the raw material used, into two large groups, A and B (Fig.…”

On the basis of a graphical classification devised by the author, the paper presents a brief analysis of the principal methods and procedures used for elaborating powders having spherical particles. The than discussion is focused on emphasizing and classifying the influence factors related to the material, processing method and equipment, which enables the obtaining of spherical particles. In the case of those methods which lead to both spherical and non-spherical particles, additional operations are needed the separation of the non-spherical particles, possibly followed by their conversion to spherical particles in a thermal field.

The conditions needed for an efficient separation together with the most important factors influencing the accuracy of the separation are emphasized. Some relationships that allow the evaluation of the covering degree of the separation surface and the volume of the charge with single dimension particles corresponding to a unit separation surface are presented. The efficiency of spherical shape particles separation and the productivity of the separation process have been analysed. Some technical and practical considerations on the separation process are given.
