Selection of Circular Vibrating Screen Parameters

The vibration force generated by the vibration source of the circular vibrating screen is an inertial force that changes in a positive and regular direction around a fixed axis. Its essence is a centrifugal force formed by the rotation of the eccentric mass around the fixed axis. The working principle of the circular vibrating screen is that after the vibrating screen is started, the vibrating screen exciter drives the vibrating screen box to make a directional jumping motion, during which the material smaller than the screen surface aperture falls to the lower layer through the screen hole and becomes the under-sieve material, which is larger than the screen surface. The material with the aperture of the screen surface is discharged from the discharge port after continuous jumping motion, and ly the screening work is completed.
 

1. Toss the index.

In general, according to the use of the sieve, the circular vibrating screen generally takes KV=3～5, and the linear vibrating screen should take KV=2.5～4. The difficult-to-screen material takes a large value, and the easy-to-screen material takes a small value. When the sieve hole is small, take the larger value, and when the sieve hole is large, take the small value.

2. Vibration intensity.

The choice of vibration strength K is mainly limited by the strength of the material and the stiffness of its components. The current mechanical level K value is generally in the range of 3 to 8, and the vibrating screen is more than 3 to 6.

3. The inclination of the screen surface.

For the circular vibrating screen, generally take 15°~25°, take the small value when the amplitude is large, and take the large value when the amplitude is small.

4. The amplitude of the screen box.

The amplitude of the screen box is an important parameter in the design of the screen, and its value must be appropriate to ensure that the material is fully layered, reduce blockage, and facilitate the screen. Usually A = 3 ~ 6mm, the larger the sieve hole is the larger value, and the smaller the sieve hole is the smaller value.
