The SIEBTECHNIK banana screening machine achieves good separating accuracy at an extremely high feed rate and with difficulttoscreen material. Its operational behaviour makes it a highspeed screen. Compared with conventional vibrating screens, the banana screen handles a considerably larger feed quantity for the same screen area.
The deep screening of small particles has become a major problem with the development of coal dry screening. Hence, coal particles with 2~6, 6~9, and 9~13 mm are selected for comparing the fractal dimension. Figure 8 displays the images and the edge images of those coal particles. The fractal dimensions of 2~6, 6~9, and 9~13 mm particles are 2. ...
