Holes of a sieve tray are arranged in triangular pitch of _________________ times the hole diameter?
Correct answer: B. 2.5 to 5
- A. 1.5 to 2
- B. 2.5 to 5
- C. 5 to 10
- D. 10 to 15
Explanation
Sieve-tray holes are commonly laid out on a triangular pitch of about 2.5 to 5 hole diameters. This arrangement provides good open area while retaining sufficient metal between holes for tray strength.
