Question

Higher holdup of solids in the rotary dryer results in:

• A. Increased kiln action, decreased kiln action, poor exposure of the solid to the gas, and an increase in power required for operating the dryer
• B. Increased kiln action and decreased kiln action
• C. Increased kiln action and an increase in power required for operating the dryer
• D. Increased kiln action, poor exposure of the solid to the gas, and an increase in power required for operating the dryer

Hint:

Optimizing holdup improves drying efficiency and reduces operational costs.

Answer 1

The Correct Option is D

Higher holdup reduces exposure to drying gas, requiring more power to achieve effective drying.
