A tube mill compared to a ball mill__________________?
Correct answer: A. Has a higher length/diameter ratio
- A. Has a higher length/diameter ratio
- B. Produces a coarser product
- C. Has a higher diameter/length ratio
- D. Uses much larger balls
Explanation
A tube mill is essentially a long, narrow grinding mill, so its length-to-diameter ratio is greater than that of a ball mill. It generally produces a finer, more uniform product rather than a coarser one.
