Rod mills employed for grinding_________________?
Correct answer: B. All A , B & C
- A. Employ a steel shell having L/D ratio of 1.5 to 3.0
- B. All A , B & C
- C. Employ steel rods of 2-12 cms diameter extending over full length of the mill
- D. Is useful for handling sticky materials
Explanation
Rod mills commonly have an L/D ratio of about 1.5 to 3, use long steel rods roughly 2 to 12 cm in diameter, and can handle somewhat sticky materials. Thus all three statements describe rod mills.
