Large Vibrating Screen Design Maintenance - 911 Metallurgist
2018.10.16 A vibrating screen must first support its own weight. Other “motionless” stresses are present in the structure as a result of cutting, bending, welding, burning, drilling, assembly, tolerancing, and manufacturing variances. Quite simply, these stresses exist whether or not the screen is operating.
