A centrifugal bucket elevator employs centrifugal force to throw material out of the buckets as they travel over the head pulley or sprocket. This type of bucket elevator operates at a higher speed and utilizes buckets spaced further apart compared to continuous bucket elevators. The result of the high speed and bucket spacing is optimized material fill and reduced interference between buckets.
Continuous bucket elevators operate at a lower speed with closely spaced buckets compared to centrifugal bucket elevators. This action permits material flow over the backside of the preceding bucket to assist with discharge. Additionally, extended sides on the buckets gently guide material into the discharge spout. These modifications create an ideal approach for fragile, abrasive, and sluggish materials. Benefits include limited material aeration and minimized breakage of friable or fragile material.
