3. Flexible routing with a cyclone at the discharge
4. Short enclosed transfers in a compact space
Select the correct match.
Answer: B
Correct answer: A-2, B-1, C-4, D-3
Four conveyors for four duties. A belt carries material over long horizontal runs at very low power per tonne. A bucket elevator lifts vertically at high capacity. A screw makes short enclosed transfers in a compact space, where its power and attrition penalties are small. And a pneumatic line offers flexible routing, ending at a cyclone that separates the material from the air.
