Which statement about screen blinding is FALSE?
Answer: C
Correct answer: It is caused by oversized apertures
This is the false statement. Blinding needs something able to lodge in the aperture, so it is near-size particles, damp material and fibrous trash that cause it; an aperture too large for anything in the feed cannot plug at all. The other three statements are correct, including the use of ball trays beneath the deck as the standard remedy.
