If the 'Ø-peak' (or 'peak') amplitude is used, the spectrum will display the maximum speed achieved by the vibrating component at the various vibration frequencies. On the other hand, if the 'rms' amplitude is used, a quantity indicative of vibration energy at the various frequencies will be displayed instead.

Freely vibrating screens. By freely vibrating screens one means screens that are supported on springs, and the box is vibrated by a vibrating mechanism (also called an exciter) which vibrates the screen box in various ways, depending on the type of vibrating unit. Circular motion. Screens with a circular motion are the most common type.

Amplitude. The amplitude of a sound wave is a measurement of the wave's height. The amplitude of a sound wave is known as its loudness or the maximum displacement of vibrating particles in a medium from their mean location when the sound is made. It is the difference between the wave's crest or trough and its mean location.

Measure the peak amplitude. Multiply by 0.707 to obtain the RMS value. Divide by 0.707 to obtain the Peak value. In some cases - specifically the use of displacement amplitudes where the analyst wants the total amount of bearing movement back and forth - the 'Peak to Peak' value is desired by the analyst. In that case, the peak value is simply ...

2. Extech's VB300 Vibration Recorder. The VB300 is a very cost effective vibration measurement instrument and is an entry level vibration recorder. Coming in at less than $300 it can be a great first option at quantifying your vibration environment. It's definitely limited in sample rate (up to 200 Hz) and total storage (4Mbit or 112K samples per axis) but for some …

Last of all, to really measure screening amplitude properly, there are tools and kits available. They attach to the equipment at a predetermined point, usually on the side of the deck, where they're then configured. From here, the amplitude, displacement metrics, and vibratory stroke length can all be observed and manually regulated.

Finally, remember that the amplitude of vibration is measured around the static equilibrium position. It means that the static displacement ystat=mg/k is …

A vibrating mechanism attached to the middle of the screen imparts rapid vibrations of small amplitude to its surface, making the ore, which enters at the top, pass down it in an even mobile stream. The spring-loaded bolts, which can be seen in section in Fig. 7, move with a hinge action, allowing unrestricted movement of the entire screening ...

Measuring Units. When we looked at the vibrating tuning fork, we considered the amplitude of the wave as the physical displacement of the fork ends to either side of the rest position. In addition to Displacement, we can also describe the movement of the fork leg in terms of its velocity and its acceleration.

Vibration Amplitude. The maximum amplitude or range of the vibration you are measuring determines the sensor range that you can use. If you attempt to measure vibration outside a sensor's range, it distorts or clips the response. Typically, accelerometers used to monitor high vibration levels have a lower sensitivity and lower mass. Sensitivity

For the circular vibrating screen, the most common reason for the poor screening effect is the inadequate inclination of the screen surface, so it is necessary to pad the back support. In practical application, the inclination angle of screen surface is more suitable when it is 20 degrees.
