Which of the following size reduction equipments employs mainly attrition for ultrafine grinding ?
Correct answer: C. All A., B. and C.
- A. Jet mills
- B. Fluid energy mill
- C. All A., B. and C.
- D. Micronizer
Explanation
Jet mills, fluid-energy mills and micronizers are essentially related types of equipment for ultrafine grinding. They primarily use high-velocity fluid streams, producing size reduction mainly through particle attrition and impact.
