During a recent site visit, a Terex Vibratory Engineer ran into a familiar challenge.

Material flowed smoothly at the feed end but stalled at discharge, throttling throughput and efficiency.
A visual inspection showed no obvious mechanical failures. On the surface, everything looked fine.

The data revealed something the eye couldnโt see:
โ๏ธ Screen motion was symmetric
โ Operating speed was well below target
โ Gโforces were significantly under the expected 7 Gs
At just 700 RPM instead of the normal 830 RPM, the screen simply couldnโt generate the energy needed to move nearโsize material off the discharge end. The result? Material hangโup and lost production โ even though the screen looked fine.
Having this data, the engineer inspected the drive system and quickly found the root cause: a broken spring in the Vโbelt tensioner, allowing belt slip and reduced speed.
