The role and advantages of butterfly screen in garbage treatment

The Butterfly Screen (also known as Disc Screen or Star Screen) is an efficient solid waste and material screening device with functions that primarily include:

Coarse and Fine Material Separation: Through the rolling action of its disc structure, the butterfly screen effectively separates materials of different sizes and shapes, making it suitable for grading and screening crushed materials, dividing them into multiple specifications based on particle size.

Wide Application: The butterfly screen is widely applied in various solid waste management fields such as household waste, construction waste, industrial waste, scrap rubber, waste paper, waste plastics, and even in the preparation process of large waste-derived fuels like RDF.

Special Material Handling: For scenarios involving wet, sticky, or easily tangled materials, the butterfly screen has excellent adaptability. Its unique rotating structure helps minimize material blockages in the screen openings, thereby enhancing the screening efficiency.

Enhanced Processing Efficiency and Economic Benefits: The butterfly screen boasts high processing capacity and screening efficiency. Compared to traditional drum screens and vibrating screens, it can handle more material within the same volume, thanks to its structural advantages and design features that reduce maintenance costs and energy consumption, extending the service life of the equipment.

Self-cleaning Function: The butterfly screen typically incorporates a cleaning mechanism inside, which effectively prevents screen openings from clogging, ensuring long-term stable operation.

In summary, the main function of the butterfly screen lies in its ability to efficiently and accurately screen and classify various solid wastes and materials, thereby promoting resource recovery and environmental protection.

Zhengzhou Zhongcheng Environmental Protection Equipment's disc screen, also known as the butterfly screen or star screen, is a device that utilizes the rotating action of discs to differentiate and screen materials based on their size and shape. By precisely adjusting the spacing between the discs, this equipment successfully achieves effective separation of various materials with significant size differences.

Zhengzhou Zhongcheng Environmental Protection Equipment's butterfly screen possesses a series of distinctive advantages: it has a simple and straightforward process flow, easy installation, convenient maintenance, and user-friendly operations. Its compact structure design results in a smaller footprint, reducing investment costs. It operates smoothly and reliably, consumes less power, and incurs lower energy costs. The built-in automatic cleaning mechanism ensures that screen openings are unlikely to become clogged. In terms of domestic waste screening, the butterfly screen demonstrates remarkable superiority over traditional drum screens, bar screens, and vibrating screens in both processing capability and screening effectiveness. The upper layer products after screening with the butterfly screen mainly consist of combustible materials like waste paper, plastics, and old fabrics, as well as small-sized combustibles containing organic substances, sand, gravel, and non-combustible solids like glass.

Regarding the internal structure of the butterfly screen, its core components consist of a series of parallel arranged discs, each with a specific aperture design. As the discs rotate, the waste materials slide between them and pass through the apertures for screening. The screening body may also be equipped with special designs to optimize material flow and prevent blockages, such as inclination angles, guiding devices, and self-cleaning mechanisms, ensuring high screening performance and stable operation.

Zhengzhou Zhongcheng Machinery Manufacturing's butterfly screen technology is especially suitable for meticulous sorting of post-crushed household waste, industrial waste, and large waste transformed into derived fuel. This technology is also widely utilized in the sorting processes of various renewable resources like scrap rubber, waste paper, and waste plastics, as well as in the production of renewable fuels like RDF (Refuse Derived Fuel). At its core, this technology adopts a unique disc configuration design that allows for controlling the size of apertures on the discs, accurately screening out waste particles smaller than the preset threshold size.

This butterfly screen system triples the processing capacity compared to traditional drum screens of the same volume, and its screening efficiency exceeds that of drum screens by 1.5 times. During operation, the butterfly-shaped screens rotate around an axis, causing vibrations in the waste materials on the screen surface. The discs are spaced appropriately, allowing for efficient sorting based on the different sizes and weights of the waste materials. Depending on the width of the discs, 15 to 20 disc panels can be installed on a single shaft. The scale of the entire equipment can be adjusted according to actual requirements by installing the corresponding number of bearing assemblies. An electric motor drives the bearings to rotate synchronously, ensuring stable operation of the entire disc screen system.

Unlike other screening devices that are prone to screen opening blockages due to wet waste, the continuous rotating dynamics of Zhongcheng Machinery's butterfly screen effectively prevent such clogging occurrences.
