Are your gas velocitys the same Mill on /off  all air to ESP must be as slow as possible across air distrubution panel to allow precollection to work and collector plates to capture dust ,kiln dust carry over may have low conductivity ,try total evaporation water air spray in ducting prior to ESP  to increase conductivity of dust ,can you increase temprature when mill off

Dear Vivek

Maybe it is a problem with the preheater top stage cyclones.

If you are interested we can help you.
