An accurate dynamic model of VFFS considering the influence of materials is significant for its dynamic analysis and screening process research, but it has rarely been
Its high frequency characteristics differentiates it from a normal vibrating screen. The high frequency vibrating screens usually operates at an inclined angle, traditionally varying between 0 and 25 degrees and can go up to a maximum of 45 degrees. Besides, it should operate at a low stroke and has a frequency ranging from 1500 7200 RPM.
Vibrating screen noise source: 1.Eccentric shaft: The vibrating screen works by relying on the centrifugal force of the eccentric block to generate the vibration force. If the eccentric force deforms the eccentric shaft to produce a bend, the relative deflection of the inner and outer bases of the bearing will occur, and the trajectory of the
company and a vibrating-screen manufacturer conducted a cooperative study of vibrating-screen noise. Rubber isolators reduced sound levels by 1 dB. Urethane screen panels did not reduce sound levels in this case. Drive noise was determined to be the dominant noise source on the screen. Damped side plates reduced vibration levels on the screen
Jun 13, 2017· I. Introduction>>> UFSZ series linear vibrating screen is designed and manufactured by Xinxiang Unitfine Machinery Co. and Chinese School of Mines, with the principle of a vibrating motor excitation. Sieving materials can be tossed on the screen surface and moved forward in a straight line, achieving screening purposes. It can sieve for 0.074-6mm any material, and 
Characteristics of Sound. The sound that we hear around us is the type of energy made by the vibration that travels through the air or any other medium and can be heard when it reaches a person’s ear. So, basically sound helps us to communicate with the other person. For example, we can hear the musical instruments like tabla, flute, a guitar due to vibration.
