In general, casing for a chain style bucket elevator should allow for a couple inches of clearance on both sides of the bucket. So if the bucket is 16" x 8", the engineer may select a 20" x 48" casing; 20" allows for 2" of clearance on each side of the buckets, while 48" accounts for the depth, providing ample clearance for the ...
