Tongli bucket elevator Introduction

Tongli cement bucket elevator is a type of mechanical conveying system used in cement plants and other industrial settings to vertically transport bulk materials, particularly powdered or granular materials like cement, clinker, and other similar products. It's designed to efficiently move these materials from one level to another within a production facility, such as from a storage silo to a processing unit or from one floor to another.

Tongli bucket elevator structure

The elevator system includes a drive mechanism, often a motor and gearbox, to provide the necessary power to move the belt or chain, along with various components like head and tail pulleys, casing or housing, and safety features to ensure efficient and safe material handling.

Buckets: These are containers or buckets attached to a conveying belt or chain. They are used to scoop up and carry the material as the belt or chain moves.

Conveying Belt or Chain: The buckets are attached to a continuous belt or chain that circulates between the bottom and top ends of the elevator. This movement is what allows the material to be lifted vertically.

Pulleys and Drives: The elevator is driven by motors and pulleys that move the belt or chain. The pulleys are responsible for guiding and tensioning the belt or chain, while the motor provides the necessary power for the movement.

Loading and Discharge Sections: The lower end of the elevator, where the material is loaded, and the upper end, where the material is discharged, are designed to ensure smooth and controlled loading and unloading of the material.

Support Structure: The elevator is typically mounted on a sturdy support structure that keeps it stable and properly aligned.

Tongli bucket elevator design principle

Material Compatibility: The design of a bucket elevator should be compatible with the specific characteristics of the material being conveyed, such as its size, density, moisture content, abrasiveness, and flow properties.

Capacity and Throughput: The design should consider the desired capacity and throughput of the elevator, which will determine the size and speed of the buckets, as well as the overall dimensions of the equipment.

Bucket Design: Buckets come in various shapes and sizes, such as deep or shallow, depending on the material and application. The bucket design should be chosen to optimize material loading and discharge while minimizing spillage and dust generation.

Bucket Material: The material of the buckets should be selected based on the abrasiveness and corrosiveness of the conveyed material. Common bucket materials include stainless steel, carbon steel, and various types of plastics.

Belt or Chain Selection: The elevator can use either a rubber belt or a chain to drive the buckets. The selection of the drive mechanism depends on factors such as the load, height, and speed requirements of the application.

Drive System: The drive system, which includes the motor, gearbox, and coupling, should be properly sized to ensure smooth and consistent operation of the elevator. Variable speed drives may be used to control the material flow rate.

Elevator Housing: The housing encloses the buckets and provides structural support. It should be designed to prevent spillage, dust emission, and material accumulation. Proper sealing is essential to minimize contamination and environmental concerns.

Discharge Mechanism: The discharge mechanism can vary based on the application. Common options include gravity discharge, centrifugal discharge, and continuous discharge. The choice depends on the material characteristics and the desired flow pattern.

Safety Features: Safety is paramount in equipment design. Bucket elevators should have safety features such as access doors, inspection ports, emergency stops, and sensors to monitor belt tension, alignment, and speed.

Industry Knowledge extension

What are the applications of bucket elevator?

Bucket elevators are versatile machines commonly used in various industries for vertical conveying of bulk materials. They consist of a series of buckets attached to a chain or belt, which transport materials vertically, typically from a lower level to a higher level. The applications of bucket elevators are widespread across different industries due to their efficient and reliable material handling capabilities.

Cement and Clinker: Bucket elevators are utilized to transport cement and clinker in cement manufacturing plants.

Ore and Minerals: Bucket elevators are used in mining operations to transport minerals, ores, and other materials to different processing stages.

Coal Handling: They can be used to move coal and other mined materials from one location to another.

What are the difference kinds of the bucket elevator?

Centrifugal Discharge Bucket Elevators: These are the most common type of bucket elevators. They use centrifugal force to throw materials out of the buckets as they pass over the head pulley. These elevators are suitable for handling fine and medium-sized materials with good flow characteristics.

Continuous Discharge Bucket Elevators: In this type, the buckets are closely spaced and have a continuous back wall, which helps prevent materials from spilling during discharge. Continuous discharge elevators are suitable for handling sluggish and sticky materials.

Positive Discharge Bucket Elevators: These elevators use a specific bucket design and close bucket spacing to ensure that materials are fully discharged from the buckets. They are commonly used for materials that tend to pack or stick together.

Super Capacity Bucket Elevators: These elevators are designed to handle large volumes of materials with high throughputs. They often feature oversized buckets and larger drives to accommodate the increased material flow.

Incline or Z-Type Bucket Elevators: These elevators are used when materials need to be transported at an incline or a vertical angle. They are especially useful when space is limited, and materials need to be moved between different levels.

Swinglink Bucket Elevators: Swinglink elevators have buckets that remain horizontal as they travel around the elevator circuit. This design minimizes product spillage and allows for gentle handling of fragile materials.

Hybrid Bucket Elevators: These elevators combine elements of different bucket elevator types to meet specific application requirements. For instance, a hybrid design might incorporate features of both centrifugal and continuous discharge elevators.
