Break rolls run at \( 500 \) and \( 125 \) rev/min. The differential ratio is
Answer: B
Correct answer: 4.0 to 1
The differential is the ratio of the two roll speeds:
\[ \frac{500}{125} = 4.0 \]
The distractor \( 625 \) multiplies rather than divides. A high differential of this order is characteristic of break rolls, where the difference in surface speed produces the shearing action that opens the kernel and scrapes endosperm from the bran. Reduction rolls run at a much lower differential, around 1.25 to 1, because their action is crushing rather than shearing.
