Limestone calcination in a rotary kiln
Apr 18, 2017The different limestones studied exhibited significant differences in heat-absorption capacity and calcination temperature which may be related to their radiative properties. Increasing particle size over a range of 0.75 to 3.5 mm resulted in an increase in both heat transfer to the bed and calcination. Rotary kiln 2,5х75 m Performance data Prev:
