Technical Field

Background

The vibrating screen operates by utilizing reciprocating rotary type vibration generated by vibrator excitation. The upper rotary heavy hammer of the vibrator makes the screen surface generate plane rotary vibration, the lower rotary heavy hammer makes the screen surface generate conical surface rotary vibration, and the combined effect makes the screen surface generate re-rotary vibration. The vibration locus is a complex space curve. The curve is projected as a circle in the horizontal plane and as an ellipse in the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotary weights.
