From Google, define screen:

http://www.google.com/search?hl=en&s...=en&defl=en &
q=define:screen&sa=X&oi=glossary_definition&ct=tit le

The 11th definition given is:

sieve: a strainer for separating lumps from powdered material or grading
particles


This definition does not require the straining element be made of a
woven mesh. I have a conical sieve that has many holes but is pressed
from sheet stainless steel. I think it matches this definition.
