The first element is decoupling. Keep in mind that sound is nothing more than a vibration. The vibration will travel (conduct) easily if there is a nice solid direct pathway to follow, like the string between two orange juice cans. If we cut the string, however, we "decouple" the pathway, and the sound vibration stops (no conduction).
When introducing the vibration, the product shakes and the particles jump without sliding on the screening surface. Each jump is an attempt of the particle to pass …

It is narrowly confined to the basic principles, as understood by the author, underlying the performance, design and application of mechanical equipment for particle separation by screening.
Forced vibration occurs when an external force is applied to a system, causing it to vibrate. Examples include the vibrations produced by an operating motor or pump. Natural vibration, also known as resonance, occurs when a system vibrates at its natural frequency. This type of vibration can be problematic if the machine's natural …

Vibration is static and dynamic imbalance of equipment. Vibration is the oscillation, or moving back and forth of an object. The word vibrations consciously or unconsciously use it as a measure of how well things are running. For vibration to get start it takes some effort, either external or internal to get vibration going, some input of ...
