Development and application of large aspect ratio vibrating screen
LV Gaochang
Abstract：According to the need of fluorite separation, the author designs an unconventional linear vibrating screen LVB 0861 with aspect ratio of 7.6, analyzes the structural dynamics of LVB 0861 with workbench. The results show that the modal parameters of the screen machine are reasonable, the displacement value is consistent with the theoretical calculation value, and the maximum value and distribution of dynamic stress meets the requirements of the operating conditions. The article carries out the inspection of vibrating screen, and the performance indexes meet the requirements of the relevant technical standards. The industrial application shows that the screening capability of fluorite is 8.0 to 10.0 t/h, and the moisture of fluorite after being sieved is 6.5 ％ to 7.8 ％.
