Vibrating screens generally handle particles of size between 5 mm and,Construction, Working and Maintenance of Electric,,To generate vibration in a vibration system, one of the shafts of the unbalance exciter is driven by stationary drive motor through cardan/propeller shaft (a shaft fitted with universal joints at each end). 8 Construction, Working and Maintenance of Electric Vibrators and Vibrating Screens www.practicalmaintenance.net.5 Vibrating Screen Common Problems And How To,1) Pipe Beam Fracture. (a) The thin wall of pipe girder may lead to fracture. At this time, the same type of thick wall pipe or the first type of pipe girder should be selected, but it should not be too large or too thick, because this will increase the vibration quality of the sieve and bring many problems;
