Bucket Elevators

The motion of the belt or chain is a device for the lifting of bulk materials. Bucket elevators enjoy a few advantages, which include simplicity of design and fabrication, req un-directional. The bucket elevator is very simple yet reliable requires minimum floor space, low initial investment.
Often bucket elevators are classified according to the bucket spacing and mode of discharge. They are:

• Centrifugal discharge elevators
• Gravity or Continuous discharge elevators
• Positive discharge elevators

The essential components of a bucket elevator are:

1. Buckets
2. Carrying medium
3. Boot arrangement
4. Head arrangement
5. Casings

Application

Typical average materials which can be conveyed by bucket elevators are:

• Limestone crushed to 25 to 30 mm size,
• Foundry sand, Coal, Coke, Sugar, Animal Feed, Chemicals, Phosphate rock, Cement mill clinker, Friable, Fragile materials, Candy, Snacks, Coffee, Rice, Seed, Soaps, Detergents, Plastic Granules

Limitations:

• Limitations of the system include the following points:
• Lump size should be under 100rnm
• Phosphate rock, Cement mill clinker, Friable, Fragile materials, Candy, Snacks, Coffee, Rice, Seed, Soaps, Detergents, Plastic Granules
• The material should not be the very sticky temperature of the materials should be ambient or slightly above
• The materials should not be excessively corrosive or abrasive
• Advantages of belt system over chain system:
• The traction element may be either an endless belt or endless chain, but a belt system is preferred under certain conditions for the following reasons:
• Higher speeds possible
• Quieter operation. Possess better abrasive resistance to materials like sand, co
