Bucket Elevator-DAHAN Vibration Machinery

Introduction of Bucket Elevator

Bucket elevator is a conveyor system consisting of a series of buckets attached to chains or belts that move the buckets vertically between the different levels of the production line, used to vertically transport bulk materials such as grain, fertilizer, or sand.

The buckets on a bucket elevator are usually made of durable materials such as steel or plastic and are designed to scoop up material as the elevator moves up. Then, the bucket unloads the materials on the top of the elevator, where they can be directed to storage bins or other processing equipment, which can be widely used in feed mills, flour mills, rice mills, oil plants of all sizes, starch plants, Vertical transportation of bulk materials in grain warehouses, ports and other occasions.

Working Principle of Bucket Elevator

The working principle of a bucket elevator is relatively straightforward. The elevator consists of a series of buckets that are attached to a chain or belt, which moves the buckets vertically between different levels of a production line.

Here is a step-by-step breakdown of how a bucket elevator works:

1. Loading: The bulk material is loaded into the buckets at the bottom of the elevator, either manually or through an automated feeding mechanism.

2. Upward Movement: As the elevator chain or belt moves upward, the buckets are lifted and transported vertically to the top of the elevator.

3. Discharge: At the top of the elevator, the buckets are tipped over, allowing the material to fall into a storage bin or other processing equipment.

4. Return: After the buckets are emptied, they continue their downward movement and return to the bottom of the elevator to be loaded again.

The movement of the bucket elevator is driven by a motor, which powers the chain or belt that moves the buckets. The speed of the elevator can be adjusted to control the rate of material transport.

Benefits of Bucket Elavator

Vertical transport

Designed for vertical transport of bulk materials, it is ideal for applications where materials need to be moved between different levels of the production line.

High capacity

Large quantities of material can be handled over long distances, making it an efficient way to move bulk materials. The lifting volume can reach 830 cubic meters per hour, and can be lifted to 40~100 meters.

Improve product quality

Helps minimize product damage and contamination during shipping, improving product quality and reducing waste.

No dust or material

Fully sealed structure, the inner edge of the bearing is sealed with glue to the sealing ring, which is dustproof, weatherproof, and can also prevent material leakage during transportation.

Customizable

Can be customized to meet the specific needs of a production line, including bucket size and capacity, elevator speed, and type of material being conveyed.

Low maintenance cost

Typically low maintenance, with few moving parts and simple design. This helps reduce downtime and maintenance costs.

Difference Between Screw Conveyor And Bucket Elevator

Both bucket elevators and screw conveyors are commonly used in material handling applications, the following are the differences between the two types of conveying equipment:

1. Conveying products: Bucket elevators are designed to transport materials vertically, while screw conveyors are designed to transport materials horizontally or inclined. Bucket elevators are ideal for applications where material needs to be moved between different levels of the production line, while screw conveyors are better for applications where material needs to be moved over shorter distances and angles.

2. Capacity: The bucket elevator has a higher capacity than the screw conveyor, and can handle larger volumes of materials over longer distances. This makes them a more efficient way of moving bulk materials.

3. Reduced product damage: Bucket elevators are designed to minimize product damage during transport because the buckets are gentle on the material being transported. And screw conveyors can cause more damage to some materials, especially if they are abrasive or brittle.

4. Maintenance: Bucket elevators require less maintenance than screw conveyors because they have fewer moving parts and a simpler design. This helps reduce downtime and maintenance costs.

Structure of Bucket Elevator

Traction parts: There are two types of tape (cotton core rubber belt/nylon core tape/steel rope core tape) and chain (plate type/ring type).

Hopper: punched and welded steel plate, divided into plastic bucket, nylon bucket.

Note: The bucket spacing is generally 2.5-3.5 times the bucket depth, about 200-400mm.

Machine head: It is composed of head wheel, machine head shell, discharge port and transmission device.

Base: base shell, bottom wheel, tensioning device, feeding hopper, deviation and speed sensing device.

Structure of Bucket Elevator

1. Loading method

(1) Take out

The material is drawn from the material by the hopper. The working resistance is required to be small, so it is mainly used to lift powdery and small bulk materials with less abrasiveness. The running speed of the hopper can reach 0.8-2m/s.

(2) Inflow type

The material flows directly into the hopper for filling. In order to prevent material spilling during loading, the hoppers of the bucket elevator are arranged in close contact. It is mainly used to lift bulky and abrasive materials. The running speed of the hopper shall not exceed 1m/s.

2. Unloading method

(1) centrifugal

The running speed of the hopper is usually 1-2m/s. The value of the centrifugal force on the material is greater than the gravity value, and the material in the hopper moves along the outside of the inner wall of the hopper for centrifugal discharge. It is used for unloading of powdery, granular and small block materials that are easy to flow.

(2) Gravity type

The running speed of the hopper is about 0.4-0.8m/s. The gravity of the material is greater than the centrifugal force, and the material moves along the inner wall of the bucket elevator hopper for gravity discharge. It is used for unloading bulky and abrasive materials. It is required to use a scale hopper, and the hoppers are arranged in close contact.

(3) Centrifugal + gravity (mixed)

The running speed of the hopper is about 0.6-0.8m/s. - Part of the material moves along the outer side of the inner wall of the hopper under the action of centrifugal force, and another part of the material moves along the inner side of the inner wall of the bucket elevator hopper under the action of gravity, which is suitable for poor fluidity and wet materials. The hopper generally chooses a shallow hopper, and the distribution method is an interval layout to ensure the completion of unloading. This unloading method combines the advantages of centrifugal and gravity elevators, and is suitable for the transportation and lifting of most materials.

Available Options

Bucket elevators are available in a variety of designs and options to meet the specific needs of your production line. Here are some of the options available for bucket elevators:

1. Bucket material: Buckets can be made of various materials, including steel, plastic or aluminum, depending on the material being transported and the environment in which the elevator will be used.

2. Bucket size and shape: The size and shape of the bucket can be customized to optimize the transportation of specific materials, such as powders or granules.

3. Traction parts: The bucket elevator can use rubber belts, steel cable belts or chains to move the bucket. The choice of belt type will depend on the specific requirements of the application.

4. Bucket elevator configurations: Bucket elevators can be designed in a variety of configurations, including single-point or multi-point discharge, vertical or inclined transport, and straight or Z-shaped configurations.
