For transporting pasty material, one will use a/an__________________?
Correct answer: C. Screw conveyor
- A. Apron conveyor
- B. Belt conveyor
- C. Screw conveyor
- D. Bucket elevator
Explanation
A screw conveyor can move cohesive, semi-solid, and pasty materials because its rotating screw positively pushes the material forward. Belt conveyors are better suited to relatively free-flowing solids, while bucket elevators require material that can be scooped.
