A new corrected formula to predict mean residence time of …
The relation between the mean residence time and holdup in a rotary dryer is given by (1) τ = L ⋅ 0.3344 S N 0.9 D ± 0.6085 G S S d p 0.5 where, τ is the residence time of granular particles (s), L is the length of rotary dryer (m), S is the slope of rotary dryer (°), N is the rotational speed (rev/s), D is the diameter of dryer (m), G is ...
