Bucket elevators are not suitable for the vertical lifting of __________ materials?
Correct answer: B. Sticky (e.g. clay paste)
- A. Fine (e.g. - 200 mesh size coal)
- B. Sticky (e.g. clay paste)
- C. Small lumpy (e.g. grains and sand)
- D. Free flowing
Explanation
Bucket elevators require material that can flow and discharge readily from the buckets. Sticky clay paste adheres to the buckets and does not discharge properly, unlike grains, sand, or fine free-flowing solids.
