Which of the following crushers can be considered as a combination of a jaw crusher and a roller crusher ?
Correct answer: A. Gyratory crusher
- A. Gyratory crusher
- B. Fluid energy mill
- C. Rod mill
- D. Ball mill
Explanation
A gyratory crusher combines the fixed-jaw crushing principle with a continuously gyrating crushing surface, giving more continuous action than a simple jaw crusher. Rod, fluid-energy, and ball mills are grinding devices rather than jaw-crusher combinations.
