The main differentiation factor between tube mill and ball mill is the ___________________?
Correct answer: A. Length to diameter ratio
- A. Length to diameter ratio
- B. Size of the grinding media
- C. Final product size
- D. Operating speed
Explanation
A tube mill is relatively long and narrow, giving it a higher length-to-diameter ratio than a ball mill. Media size, product size and speed may overlap, so they are less reliable as the main distinction.
