The basic principle of the SYT series three-dimensional vibrating screen is to use a weight (unbalanced weight) installed up and down the motor shaft to convert the rotational motion of the motor into a horizontal, vertical, and tilted three-dimensional motion, and then transfer this motion to the screen surface , causing the material to expand involute motion on the screen surface, so this series of vibrating screens is also called a rotary vibrating screen. This series of vibrating screens has the advantages of long material running trajectory and high screen surface utilization. By adjusting the phase angle of the upper and lower weights, the movement trajectory of the material on the screen surface can be changed. It can carry out fine screening of materials and probability Screening etc.
