What

are Bucket Elevators

A

bucket elevator or grain leg, is a machine that convey flowable bulk

materials vertically. It is useful in oil mill machinery and consist

of buckets, a belt, to carry the buckets and transmit the pull,

machine to drive the belt and accessories for loading the buckets or

picking up the material. it is important accessory for oil mill

machinery as it can convey light to heavy materials at ease.

Bucket

Elevators are one of the most popular systems in use today for

elevating bulk materials. Their inherent simplicity makes them a

popular choice for handling bulk materials and in processing

applications. Continuous developments in bucket shape, head and boot

profiles, manufacturing and operating specifications.

With a

bucket elevator, most free flowing materials and other materials with

poor flow characteristics can be successfully handled. The rate at

which material can be elevated depends on many factors in addition to

the obvious effects of bucket design, capacity and speed.

Types

of Bucket Elevators

The

most common elevator is a centrifugal discharge elevator, which may

be vertical or inclined. The action of centrifugal force drives the

vertical elevators to put the oil into the discharge chute and be run

at a relatively high speed. Inclined elevators have the buckets

placed little apart or set close together may have the discharge

chute set partly under the head pulley. The speed of the inclined

elevator is low because it doesn't depend on the centrifugal

force.

All vertical elevators have spaced buckets with rounded

bottoms. The materials from a boot, a pit or a pile can be easily

loaded to a centrifugal elevator. The shape of buckets are triangular

and close to on the belt with little or no space in between them.

This type of elevator are being used to carry heavy material, and

lift at a slow pace. Unlike earlier elevators, which used to use

small, flat steel buckets, nowadays modern elevators uses a rubber

belt with plastic bucket. These are more convenient and easy to use.

Further, the pulleys are being used at the top and bottom and driven

by an electric.

Functions

of Bucket Elevators

The

main function of elevator is to continue pulsating flow of material

through a vertical handling. Apart from centrifugal discharge type,

there are others such as positive discharge type, continuous type and

super capacity elevators. In case of large materials, lumpy and

abrasive materials slow elevators may be used without scooping the

material is lifted. The chains or belts as traction element are used

and different bucket shapes, provide universal possibility of

combinations. Apart from conventional bucket elevators there are

overlapping buckets type elevator, shelf elevator, cradle elevator

etc.
