The following is a detailed introduction to the role and working principle of the disc screen. The content will focus on its design principle, functional characteristics, application field and working principle, in order to meet the length requirement of 2000 words.

Disk Screen

A. The role of the disc screen

The main function of the disc screen is to efficiently screen materials of different sizes and shapes. It is widely used in the treatment of various types of solid waste such as domestic waste, building decoration waste, stale waste, and kitchen waste. Its significant advantages are large processing capacity, high screening accuracy, no blockage, stable operation, etc. These characteristics make the disc screen show great potential in garbage sorting and resource recycling.

1. Large processing capacity: The special structure of the disc screen significantly improves its processing capacity per unit area. Compared with traditional screening equipment, its processing capacity can be doubled or even more. This means that in the same time, the disc screen can process more garbage materials, thereby greatly improving production efficiency.

2. High screening accuracy: The disc screen can effectively separate materials with large size differences by adjusting the disc gap. At the same time, the disc is designed with holes of different sizes, which can separate garbage particles of different sizes as needed. This high-precision screening ability makes the recycled aggregate cleaner and more uniform, providing high-quality raw materials for subsequent production and application.

3. No clogging: The disc screen adopts a unique rotating design, which allows the material to be continuously turned over on the screen surface, effectively avoiding the problem of material clogging. This feature is particularly prominent when dealing with wet and sticky materials and construction waste, allowing the disc screen to maintain efficient operation.

4. Stable operation: The disc screen adopts a modular design, which is convenient for maintenance and structural adjustment. At the same time, the special wear-resistant sprocket, chain linkage and original tensioning chain design ensure that the equipment has extremely high operating stability. This stability not only improves the screening efficiency, but also extends the service life of the equipment.

5. The disc screen also has the characteristics of small footprint, optional and customizable sieve holes, and can choose the appropriate number of modules according to customer needs, which is convenient for later maintenance and structural adjustment. In terms of technology, the disc screen adopts variable frequency stepless speed control, with low energy consumption, high safety and adjustable processing capacity. These characteristics make the disc screen widely used in the field of garbage sorting, promoting the development of environmental protection.

B. Working principle of disc screen

The working principle of the disc screen is mainly based on the rotation and screening effect of the disc. The following is a detailed explanation of its working principle:

Disk Screen

1. Disc rotation: The disc screen is usually composed of multiple perforated discs installed in parallel, which are rotated by a motor. The rotation speed of the disc can be adjusted by frequency conversion control to meet the screening needs of different materials.

2. Material separation: When the garbage material enters the disc screen, it is affected by the rotation of the disc. Due to the gravity and the centrifugal force generated by the rotation of the disc, small particles of garbage will fall through the holes on the disc and enter the collection device below. The large particles of garbage are taken to the other end by the disc for centralized processing or further sorting.

3. Screening accuracy adjustment: The screening accuracy of the disc screen can be achieved by adjusting the disc gap. When it is necessary to separate materials with large size differences, the disc gap can be appropriately increased; when high-precision screening is required, the disc gap can be reduced. This adjustment method enables the disc screen to adapt to the screening needs of different materials.

4. Material flipping: In order to avoid material blockage, the disc screen adopts a unique rotation design to make the material flip continuously on the screen surface. This flipping effect not only helps to evenly distribute the material, but also effectively prevents the screen hole from being blocked and improves the screening efficiency.

5. Frequency conversion control: The disc screen adopts frequency conversion stepless speed control, which can adjust the rotation speed according to the material characteristics and screening needs. This control method not only improves the screening efficiency, but also reduces energy consumption and noise levels, and improves the safety and stability of the equipment.

C. Application fields of disc screens

The disc screen is widely used in many fields due to its high efficiency, flexibility and stability, mainly including the following aspects:

Disk Screen

1. Domestic waste treatment: In urban domestic waste treatment, the disc screen can efficiently separate recyclables, organic waste, etc., which provides convenience for subsequent resource reuse and harmless treatment.

2. Construction waste treatment: The disc screen plays an important role in construction waste treatment. Through efficient screening, construction waste such as bricks and concrete waste can be converted into recycled aggregates for the production of new environmentally friendly materials such as recycled concrete and recycled bricks.

3. Agricultural waste treatment: In agricultural waste treatment, the disc screen can separate organic materials such as crop straw and livestock and poultry manure, providing raw materials for the development and utilization of biomass energy.

4. Industrial waste treatment: In industrial waste treatment, the disc screen can efficiently separate recyclable metals, plastics and other materials to achieve resource recycling and harmless treatment of waste.

PS: The disc screen plays an important role in garbage sorting and resource recycling with its high efficiency, flexibility and stability. In the future, with the continuous deepening of technological innovation, intelligent development, resource utilization and policy promotion, the application field of the disc screen will be further expanded, making greater contributions to the development of environmental protection.
