As particle size is reduced__________________?
Correct answer: C. Screening becomes progressively more difficult
- A. Capacity and effectiveness of the screen is increased
- B. Screening becomes progressively easier
- C. Screening becomes progressively more difficult
- D. None of these
Explanation
Very small particles are difficult to screen because they tend to agglomerate, pass slowly through the apertures, and blind the screen. Thus, screening becomes progressively more difficult as particle size decreases.
