At present, there is no uniform formula for calculating the final residence time of lime in rotary kiln. Most of the formulas of cement rotary kiln are applied to lime system, but the composition and particle size of lime and cement are obviously different, so the calculation time is not accurate enough, which will bring inaccuracy to the ...
