Abstract

At present, there is still a lot of room to improve the separation effect of coal blocks, which is mainly due to the lack of effective support for the screening of coal blocks within a certain size and diameter range, which seriously affects and restricts the overall operation efficiency of coal preparation plant and the improvement of economic benefits of operation. Based on this, this paper first studies the current situation and problems of coarse slime separation process, then analyzes the numerical simulation technology and process of coarse coal slime particle number process in water medium fluidized bed, and finally gives the numerical simulation and experimental verification of coarse coal slime separation in water medium fluidized bed.
