The working principle of the circular vibrating screen is ingeniously designed around a state-of-the-art rotary vibration mechanism. When the motor diligently generates centrifugal force via a sophisticated set of eccentric blocks, it orchestrates the screen to glide seamlessly in a circular motion. This dynamic motion ensures that materials are elegantly dispersed across the screen surface, swiftly guiding them towards the screen's outlet. By utilizing screens with varying apertures, materials are meticulously graded according to their particle sizes, providing an efficient and precise classification process.
