Linear Vibrating Screen

Introduction: The linear vibrating screen consists of a screen box, a vibrating motor, vibration damping springs, a bracket, and multiple layers of screen mesh. The screen box is welded from steel plates to ensure rigidity, and the screen mesh can be made of stainless steel, polyurethane, or nylon. The vibrating motor drives the vibrator via a V-belt or direct drive, generating linear motion. The vibration frequency can be adjusted via a frequency converter to meet varying production requirements.

Working principle: The equipment is based on the synchronous counter-rotation of dual motors. The exciting force generated by the eccentric block is offset in the direction parallel to the motor shaft, and the vertical direction is superimposed as a resultant force, driving the screen body to vibrate periodically back and forth in a straight line. The material on the screen surface is acted upon by the combined force of the exciting force and gravity, and moves forward in a parabolic jump. Particles smaller than the screen hole pass through the screen and fall, while coarse particles continue to move forward to the discharge port. The screen surface inclination and vibration frequency work together to control the material movement speed and screening rate, achieving precise classification.
