Introduction to Rotary Feeder

The rotary feeder, also referred to as a star - shaped discharger, is a crucial piece of equipment designed for the conveyance and metered feeding of solid materials.

It holds an essential position in industrial production workflows.

Working Principle

The rotary feeder primarily comprises components including a rotor equipped with multiple blades, a housing, end caps, and a drive mechanism. When the motor

activates the rotation of the rotor, materials enter the compartments formed between the rotor blades through the feed inlet. As the rotor revolves, the materials

are transported to the discharge outlet, thereby enabling continuous material transfer. During this process, the rotor blades serve the dual functions of sealing and

metered conveyance, effectively preventing material leakage and air - flow inter - mixing.

Structural Characteristics

Excellent Sealing

Specialized sealing arrangements, such as gaskets and labyrinth seals, are employed. These ensure effective prevention of material and gas leakage, rendering the

equipment suitable for applications demanding stringent sealing conditions.

Compact Configuration

Characterized by its small footprint and light weight, the rotary feeder is easy to install and maintain. Its compact design saves valuable space, facilitating seamless

integration into diverse production systems.

High Wear - resistance and Durability

Components in contact with the materials are typically fabricated from wear - resistant materials, such as wear - resistant alloy steels or ceramics. This enhances the

equipment's service life and reduces maintenance costs.

Precise Metering

By adjusting the rotational speed of the rotor, precise control over the material conveyance rate can be achieved, meeting the metered - feeding requirements of

different production processes.

Application Domains

Power Generation Sector

Utilized in the coal - feeding systems of coal - fired boilers, it uniformly transfers coal from the coal bunker to the boiler's combustion system, ensuring stable boiler

combustion.

Chemical Industry

During the transportation and batching of various chemical raw materials, the rotary feeder accurately regulates the quantity of materials introduced, guaranteeing

the smooth progression of chemical reactions.

Building Materials Industry

Employed for the conveyance of powdered materials like cement, lime, and gypsum, it is a vital component in cement production lines and building materials

manufacturing processes.

Grain Industry

In the stages of grain processing and storage, it is used for grain transportation and measurement, ensuring accurate grain distribution and processing.

Environmental Protection Sector

In environmental protection projects such as waste incineration and sewage treatment, it is utilized to convey solid waste and treatment agents, enabling the stable

operation of environmental protection equipment.

The rotary feeder, with its high - efficiency, stable, and precise material - handling capabilities, plays a pivotal role in numerous industrial sectors. It provides robust

support for the automation and enhanced efficiency of industrial production. As technology continues to evolve, the rotary feeder is also undergoing continuous

innovation and development to meet the increasingly intricate demands of industrial production.
