A bucket elevator is a complex system with many variables to consider. As discussed in previous chapters these include bucket size, bucket spacing, speed, and various components. Some of the most critical, and sometimes hard to understand principles of bucket elevator design include the sizing of the motor and shafts.

The bucket design allows the product to flow down the back of the preceding bucket; Typical speeds 0.5 to 1.0 m/s; Due to the lower speed, the foot print is generally larger than that of a centrifugal elevator of the same capacity; The lower speed and style of bucket means that this style of elevator is less aggressive than the centrifugal type ...

Capacity Calculating Calculating Bucket Elevator Capacity STEP 1: Multiply the CAPACITY of the bucket times the NUMBEROFBUCKETS per foot (12 divided by spacing) times the NUMBER OF ROWS of buckets. This will give the capacity in cubic inches of each running foot of the belt or chain. ... SPEED of the belt or chain FPM (Feet Per Minute) CUBIC IN ...

A bucket elevator consists of a series of uniformly fed buckets mounted on an endless chain or belt which operates over head and foot wheels. The buckets are used to elevate (usually vertically) pulverized, granular, or lumpy materials. The material is received at the boot, raised and then discharged by passing over the head wheel at the top ...

The most common cause for loss of capacity in an elevator is the bucket discharge, which can be caused by the incorrect belt speed in relation to the pulley diameter, the wrong bucket for the material and the wrong head shape. Below is a table showing the three types of discharge and their common characteristics. Discharge

Too slow and the material slides from the upturned bucket as it comes over the top pulley and falls back to the bottom of the elevator. Too fast and the material is flung out too soon and hits the top of the elevator before falling back to the bottom. Formulas are available to determine the right belt speed and throw for the material.
