Which statement about a cyclone is FALSE?

  • A.It separates stones from the grain stream
  • B.It recovers dust from an air stream
  • C.Its efficiency rises with inlet velocity
  • D.It should sit ahead of the fan

Answer: A

A cyclone never handles the grain at all; it works only on the aspiration air stream and its entrained dust. Stones are the destoner's business entirely, and the other three statements in the question are perfectly correct.
