The head section consists of the drive shaft, sprockets, drive source (such as a motor) and the elevators discharge. The mid-section contains the elevators support structure along with the chains and buckets. Most elevators are fully encased for safety and dust control, although a few elevators do operate with just a skeleton support structure.

which is now expanded in this work to validate and optimize bucket elevators. 4.1 Discharge of Buckets There are three methods of bucket elevator discharge – gravity, mixed, and centrifu-gal. The abovementioned pole method is good enough to make a quick basic judg-ment how the proposed bucket elevator will discharge (Fig. 4.5).

Bucket Elevator In centrifugal-discharge bucket elevators, the material to be elevated is dug out of the boot and discharged by centrifugal force. They are comparatively high-speed el evators, used where the percentage and size of lumps are at a minimum. 3.1.2 Continuous Bucket Elevator In continuous bucket elevators, buckets closely spaced

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 ...

Example - Force and Power to Lift an Elevator. An elevator with mass 2000 kg including passengers are moved from level 0 m to level 15 m . The force required to move the elevator at constant speed can be calculated as. F c = (2000 kg) (9.81 m/s2) = 19820 N. The power required to move the elevator between the levels in 20 s can be calculated as.

Bucket speed = 15 m/minute, bucket pitch = 0.25 m/bucket (or 4 buckets/m), bucket working volume = 0.005 m3 (or 5 litres) 15 m/minute x 4 buckets/m = 60 buckets/minute. Substituting in the bucket working volume we get: 0.3 m3/minute of volumetric throughput capacity. As the product handling industry work using throughput capacity per hour, we ...
