Natural Frequency Natural frequency conveying moves materials smoothly and efficiently in a gentle series of "throws and catches." Spring systems are custom engineered and tuned to the weight of the conveying trough material. This produces a system that resonates at the most desired natural frequency. Most important, when the conveyor
Vibration and instability can shorten the life of any equipment, as well as transmit this vibration to other adjacent structures giving rise to high frequency noise. Spring isolators are ideal for limiting the transmission of vibration, shock and structure borne noise over a variety of applications – from engine generator sets and small fans ...
Difference 2#: Working principle The vibrating conveyor uses the reciprocating vibration of the conveying trough to convey the material. There are two ways of conveying the material in the trough, which is the sliding motion and the throwing motion. As long as the appropriate kinematic parameters are determined, such as amplitude, Frequency, …
