YiSun Biological Co., Ltd., a resource recycling company specializing in the production of biological organic fertilizers, is located in Huangzhong District, XiNing City. After using the Zhongcheng drum screen for one year, the company provided positive feedback.

Lingyun wang, Facility Owner: "The drum screen has been a game-changer for us. The consistent particle size and reduced contaminants have allowed us to produce a premium compost product that our customers love.Investing in a drum screen was one of the best decisions we made. It’s robust, low-maintenance, and has drastically increased our processing capacity. The return on investment was quicker than we anticipated."

Drum screen, also known as a rotary drum screen or trommel screen, is an essential piece of equipment used in composting plants for the separation of compost materials based on size. It is a rotating cylindrical screen that separates fine compost from coarse materials, helping to produce high-quality compost. Here’s a detailed overview of drum screens and their applications in composting plants:

Components of a Drum Screen

Rotating Drum: The cylindrical screen that rotates to separate materials. It is typically made of steel and perforated to allow fine particles to pass through.

Motor and Drive System: Powers the rotation of the drum, ensuring consistent and controlled movement.

Feed Hopper: Where the compost material is loaded into the drum screen.

Discharge Chutes: Separate chutes for fine and coarse materials, directing them to their respective collection points.

Support Frame: Provides structural support to the entire setup, ensuring stability and durability.

Brushes/Cleaning Mechanism: Keeps the screen clean and prevents clogging, ensuring efficient operation.

Advantages:

Efficient Screening: Effectively separates fine compost from larger debris, improving the quality of the final product.

Scalability: Available in various sizes to accommodate different processing capacities.

Durability: Robust design ensures long-term use with minimal maintenance.

Versatility: Can be used for screening a variety of materials, including soil, sand, and gravel.

Characteristics

High Throughput: Capable of processing large volumes of material quickly.

Low Maintenance: Generally requires minimal maintenance due to its simple mechanical design.

Adaptability: Can be customized with different screen sizes and drum lengths to suit specific applications.

Reduced Operational Costs: Automates the separation process, reducing the need for manual labor.

Working Principle and Application

Loading: Compost material is fed into the rotating drum via the feed hopper.

Separation: As the drum rotates, smaller particles fall through the perforations, while larger materials continue to move along the length of the drum.

Collection: Fine compost is collected in a chute below the drum, while coarse materials exit at the end of the drum.

Applications in Composting Plants

Primary Screening: Initial separation of compost materials to remove larger debris and contaminants.

Secondary Screening: Further refinement of compost to achieve a consistent particle size.

Quality Control: Ensures that the final compost product meets quality standards for particle size and purity.

Maintenance and Care

Regular Cleaning: Keep the screen and brushes clean to prevent clogging.

Inspection: Regularly check for wear and tear on the drum, motor, and other components.

Lubrication: Ensure that moving parts are adequately lubricated to prevent mechanical failures.

Adjustments: Adjust the screen angle and rotation speed as needed to optimize performance.

Purchasing Considerations

Capacity Requirements: Choose a drum screen with a capacity that matches the volume of compost processed.

Screen Size: Select the appropriate perforation size for the desired compost particle size.

Durability: Consider materials and build quality to ensure longevity.

A drum screen is a vital component in the composting process, enhancing the quality and consistency of compost products. By carefully selecting and maintaining the right drum screen, composting plants can achieve efficient and effective separation, leading to higher quality compost and improved operational efficiency.
