Tension and compression forces are transferred by anchorage of the ribbed rebars, and by bearing onto anchorage plates. Shear forces are transferred to the concrete by bearing onto the shank of the bolt.

If this procedure is not followed the motor mounting bolts will bend when tightened! Once bent these bolts lose tension and will ultimately fail.
view moreThe most common failure mode of bolts is fatigue failure. Bolts can fail by due to several reasons including (1) the bolt had not been sufficiently preloaded/tension during installation, (2) had lost its preload during service, (3) the applied cyclic loading had been excessive – far beyond the strength of the bolt and/or (4) the bolt had been ...

In the case of a vibrating screen, the vibrations are given to the screen to effect the separation of solid particles into two size fractions. Vibrations given keep the solid particles moving. Proper selected frequency and amplitude keep the capacity constant. In the case of a vibrating screen ...
