The three-dimensional rotary vibrating screen uses a vertical motor as the excitation source. The upper and lower ends of the motor are equipped with eccentric weights to convert the rotating motion of the motor into a horizontal, vertical, and inclined three-dimensional motion, and then transfer this motion to The screen surface makes the material expand and involute on the screen surface, so this series of vibrating screens are called rotary vibrating screens. Rotary vibrating screen has the advantages of long material running trajectory and high screen surface utilization. Adjusting the phase angle of the heavy hammers at the upper and lower ends can change the trajectory of the material on the screen surface. The material can be finely screened and screened with probability. Grading.
After the rotary vibrating screen is started, its power device, namely the eccentric masses with different phases at the upper and lower ends of the vibrating motor, generates a composite inertial force due to the effect of high-speed placement. Continuously reciprocating movement under the action of the ground, driving the screen surface to periodically vibrate, so that the material on the screen surface will move directional and enthusiastically along with the screen box, during which the material smaller than the aperture of the screen surface will fall to the lower layer through the screen hole , Becomes the under-screen material, the material larger than the aperture of the screen surface is discharged from the discharge port after continuous jumping motion, and the screening work is finally completed. The trajectory of the vibrating body of the rotary vibrating screen is a complex three-dimensional curve in space. The projection of this curve on the horizontal plane is a circle, and the projection on the two vertical planes is two identical ellipses. In actual application, by adjusting the relative phase of the eccentric blocks at the upper and lower ends of the vibrating motor, the movement trajectory of the material on the screen surface can be changed, so as to achieve different screening operations.
