The working principle of the density screening machine is to achieve the separation of materials by utilizing the differences in the movement trajectories of materials with different densities under the influence of fluid mechanics.
When materials are added to the fluid medium, materials of different densities occupy different positions and are subjected to different forces in terms of magnitude and direction. Therefore, their movement trajectories are also different. Under the action of the circulation system of the fluid medium, the materials will stratify on the screening system (including the screen and the screen mesh), thereby achieving separation.
