MOHAN-PROCESS
Have you calculated the velocity inside the TAD?It should be Greater than 25 m/sec.If the carrying velocity is less than the settling velocity the material will get accumulate.what is the inclination of your TAD?TAD is located towards the kiln rotation or opposite to the kiln rotation?Any variation with the TAD temperature?What is the condition of the Damper in the stoppage inspection?Any Control available over the Damper?
