Question

Stationary screens can be used for wet particles.

(a) True

(b) False

This question was addressed to me during an interview.

Asked question is from Unit Operations topic in section Sedimentation and Centrifuge, Mixing, Size Reduction and Separation and Material Handling and Transportation of Food Engineering

Answer 1

Correct option is (b) False

To explain I would say: Stationary screens only rely upon gravity for the settling and movement of particles from one screen to another. Hence they cannot be used for wet particles.
