We are facing the problem of frequent calcined powder lumps in kiln and the lumps discharged in to cooler and clinker crusher will get jammed, The lumps are soft and contain the calcined powder inside, Please any body suggest what is the reason for the lump formation and how to overcome the problem.
We are operating Rotary kiln 3.0m Dia x 42.5m Length with 5 stage suspension Preheater having capacity of 500 t/d, due to the above problem the production drop down to 350 t/d.
