Rotary kiln fuel consumption

Oct 08, 2014 The energy consumption of the kiln as fuel for calcination, studied in this work, varies mainly with kiln technology, process setup, raw material properties, and product properties. The variations are large. Shaft kiln operations are reported at 3.2–4.9 GJ per ton product and rotary kilns at 5.1–9.2 GJ per ton product 3
