used technique in condition based maintenance and rely a lot on instrumentation Machine vibrations stack a lot of information about the condition of a machine. Measurement and analysis of the vibration response gives a lot of information with relevance to fault conditions in different types of machines (Khwaja, Gupta, & Kumar, 2010).


Conclusion The bottom line in noise and vibration control, as in virtually all other engi-neering efforts, is cost-effectiveness, which translates into achieving work-able, inexpensive solutions to complex problems. Maximum advantages of reducing noise and vibration at the source can be realized by careful plan-ning, thoughtful design, and proper

5 Construction, Working and Maintenance of Electric Vibrators and Vibrating Screens Unbalance Motors They are also known as vibration motors. Unbalance motors are provided and are suitable for driving vibrating systems, such as vibrating pipes, vibrating feeders, vibrating screens,


This permits a quick change of the screen mats and an optimum product flow on the screening elements. This vibrating screen machine is carried out as a circular vibrating screen and is driven by an imbalance shaft drive with standard three-phase AC motor. The sub-frame compensates the residual vibrations of the screen.


Figure is multiplied by the sq. footage of the screen deck. • Calculation gives the basic capacity of each deck and the total capacity of the vibrating screen. • The vibrating screen capacity is determined: • Using a standard sizing formula (9 variables). • Basic capacity of each deck opening. • Unique factors of that application. •
