Centrifugal discharge in a bucket elevator requires
Answer: C
Correct answer: A relatively high belt speed
Centrifugal discharge relies on the material being thrown clear of the bucket as it rounds the head pulley, which requires enough speed for the centrifugal effect to overcome gravity at the top of the arc.
The buckets are spaced apart so the discharging material has a clear path. The alternative, continuous discharge, runs at low speed with buckets close together, the material sliding out over the back of the bucket in front - gentler on fragile products, and used where breakage matters more than throughput.
