Jun 06, 2008 · Kiln feed to clinker ratio. That factor is increased by the dust losses from the preheater to the raw mill and dust filters. If your factor is 1.75 then you must have high dust losses from the preheater so improving collection efficiency will reduce the factor. However, it will also increase the pressure drop across the preheater.
The raw mill and preheater/precalciner use kiln exhaust gases to dry, heat and calcine the raw feed before it enters the kiln. The counter flow of raw materials and exhaust gases in the raw mill and preheater act as an inherent semidry (raw mill) and dry scrubber (preheater) to control SO 2 emissions. Some SO 2 may also be dry scrubbed in the baghouse particulate control system.
