The working principle of the circular vibrating screen revolves around its highly efficient rotary vibration mechanism. As the motor exerts centrifugal force through strategically positioned eccentric blocks, the screen embarks on a dynamic circular motion. This movement ensures that the material is meticulously and uniformly distributed across the screen surface, facilitating its swift journey towards the screen's outlet. During this process, the material is systematically graded based on particle size, as it navigates through screens with varying apertures, delivering unparalleled precision in sorting.
