15-03-2021  The vibrating flip-flow screen (VFFS) with elastic sieve mats has been widely used for screening fine-grained minerals due to its good performance ( Zhou et al., 2020a, Wu et al., 2019 ). To date, many researchers have conducted numerous studies on the stability of the dynamic response of vibrating screens.

How to Identify, Correct a Resonance Condition

18-04-2021  Natural frequency is a characteristic of every machine, structure and even animals. Often, resonance can be confused with the natural frequency or critical frequency. If equipment is operating in a state of resonance, the vibration levels will be amplified significantly, which can cause equipment failure and plant downtime.

Basics of Structural Vibration Testing and Analysis ...

Frequency Response Function (FRF) is computed from two signals. It is sometimes called a "transfer function." The FRF describes the level of one signal relative to another signal. It is commonly used in modal analysis where the vibration response of the structure is measured relative to the force input of the impact hammer or shaker.

How to Diagnose and Prevent Resonance - Pioneer

07-06-2016  The frequency that this free vibration naturally wants to occurs at is known as the natural frequency. If an object is being forced to vibrate at its natural frequency, resonance will occur. This is what causes large amplitudes of vibration when a machine’s running speed is at or near a natural frequency even if the force inputs are low.

Choosing the Proper Vibratory Screener

Install a ball tray deck beneath the screen section. The ball tray has compartments with perforated plate at the bottom. Balls are placed in each compartment and freely bounce during screener operation. The balls strike the underside of the screen surface and randomly knock out the plugged material.
