Study on the Separation Effect and Mechanism of 6−0.5 mm Coal in Fluidized Bed with Vibratory Combined Force Field
February 22, 2023
Abstract
As a crucial power source, the separation of fine coal has gradually become a research focus in the coal separation field. In this study, the vibratory combined force field fluidized bed has been introduced into fine coal (6−0.5 mm) separation research. The kinematic characteristics of the fluidized bed was studied. The spatial distribution of coal on the bed under the action of vibration and air was clarified. The influence of different factors on the degree of ash segregation (Sash) was analyzed, and the optimal operation parameters were evaluated. The results showed that the vibratory combined force field fluidized bed was characterized by round-trip periodic movement. The maximum vibration amplitude on the X-axis of the main vibration direction was 6.88 mm, the velocity amplitude was 287.60 mm/s, and the acceleration amplitude was 10.43 m/s2. At 34 Hz and 5.68 m/s for vibration frequency and air speed, the maximum ash segregation of the product was 1.896, and the yield and ash contents were 85.28% and 10.69%, respectively.
