vibrating screen exciter frequency

These screens vibratearound 298mm/s RMS in the highest direction of motion. I found a beauty of a defect when I was conducting a vibrating screen structure survey, I decided to collect the usual routine vibration data from the exciter gearboxes via a flat magnet mount and found an inner race defect!

Vibrationis transmitted to thescreendeck by theexciter(vibrator) assembly. The vibrator assembly comprises eccentric masses mounted on theexcitershaft. The shaft is supported on either two or four (depending on the capabilities of the bearing and housing design)vibration screenduty self-aligning double row spherical roller bearings.

Thevibratingmachine with the dual-mass system driven by two exciters is avibrating screen. Tables 1 and 2 show the parameters ofvibrating screenand parameters of two exciters of thevibrating screenseparator as shown in Figure 9, respectively.

Different to other type screens, the vibromotors of high-frequency screens are mounted on each deck instead of on the screen body. Aggressive vibration is applied within a range of3600–5000 RPMdirectly to the screen media, allowing for higher capacity and more efficient sizing when compared with conventional screens.

There are three regions that will lead to the sudden increase of vibration acceleration: (1) the load weight variates within 0–50 kg and excitation frequency variates within 40–60 Hz; (2) the load weight variates within 10–100 kg and excitation frequency variates within 50–90 Hz; (3) the load weight variates within 80–200 kg and excitation frequency variates within 70–100 Hz.

Sep 01, 2009· After structural optimization, the first elastic deformation frequency of the vibrating screen is lowed by 14.17%, the second elastic deformation frequency is reduced by 12.29% and the total mass of vibrating screen decreased 2.35%.
