A _____________ mill is a revolving mill divided into two or more sections by perforated partitions in which preliminary grinding takes place at one end and the finishing grinding at the discharge end?
Correct answer: A. Compartment
- A. Compartment
- B. Tube
- C. Rod
- D. Pebble
Explanation
A compartment mill is divided by perforated partitions so that coarse grinding occurs in the first compartment and progressively finer grinding occurs toward discharge. This staged arrangement distinguishes it from a simple rod or pebble mill.
