Gentleman, had an old TYLER SCREEN, worked fine for past 20 years and advised following situation:
- he had changed the TRIPLE nested coil springs on each of 4 corners and noted that the vibrating screen was not VIBRATING the whole structure WILDLY and quite erratically.
- asked why this would be the case, to which on the phone, i stated, beats me
- upon further troubleshooting, i asked if anything had changed lately and the answer as usual was NO.......to which my response as usual was,,,,,,"are you sure" .......oh,,,,,LET ME see.
- turns out they had replaced a leg that was rotted or damaged or weakened over the years on the screen support structure. I asked if they measured properly to ensure balance of vibrating screen on the structure was maintained, he assumed yes.
- I asked him to have a TRANSOM CHECK DONE On all 4 corners....and they actually found the new leg....was 2 3/4" SHORTer THAN the other 3 legs. This was the cause of the erratic vibration.
- WHEN FIXED, problem went away. VERY important to have all 4 corners EQUAL and balanced and level always.
And.........how is your old structure doing today? ■
