The exact introduction about Air Drum Separator

Air drum separator:

The working principle of the air drum separator is mainly to use air as a medium and to separate solid waste by precisely controlling the airflow. The core is based on the density and particle size differences between different materials. Under the action of the airflow, lighter materials will be carried up by the airflow or transported farther horizontally, while heavier materials will settle because the rising airflow cannot support their weight, or move a shorter distance horizontally due to inertia. 

Specifically, the working process and key components of the air drum separator include:

1.Airflow generation: The equipment is usually equipped with a centrifugal fan or similar airflow generating device to create the necessary updraft or horizontal airflow.

2.Material supply: Solid waste is evenly fed into the sorting area through a belt conveyor or other feeding device.

3.Sorting chamber design: The wind sorter is designed with specific airflow channels and separation areas inside, which can be a horizontal airflow air sorter (horizontal) or an updraft airflow sorter (vertical). In these areas, the speed and direction of the airflow are carefully designed to optimize the sorting effect.

4.Material separation: Light materials (such as paper, plastic, fabric, etc.) are greatly affected by the airflow and are carried to the upper or far end of the equipment and collected through the light material outlet. Heavy materials (such as glass, metal fragments, etc.) are not easily carried away by the airflow due to their high density, and will settle to the bottom or side of the equipment and be output through the heavy material conveyor.

5.Airflow control technology: Advanced wind sorters use complex airflow control technology, such as a positive and negative pressure interlaced airflow environment, to improve sorting efficiency and accuracy.

6.Multi-stage sorting: For situations where higher sorting accuracy is required, multiple sorting stages may be set up, with each stage further separating materials in different density ranges.

As an efficient solid waste treatment technology, wind separator has the following significant advantages:

1.Low energy consumption: Compared with other sorting technologies, such as magnetic separation or wet sorting, wind sorters generally have lower energy consumption, which is beneficial to reducing operating costs.

2.Low noise: The design focuses on reducing noise generation, so that the equipment has less impact on the surrounding environment during operation, and is suitable for operation near residential areas.

3.Large processing capacity: The wind separator can handle a large amount of solid waste and is suitable for large-scale garbage treatment plants, improving the efficiency of waste treatment.

4.High efficiency: Through precise air flow control, materials of different densities can be efficiently separated and the resource recovery rate can be improved.

5.Good sorting effect: It is especially effective for sorting light materials such as paper, plastics, etc., which helps to improve the quality of recycled items.

6.Strong adaptability: It can be used for various types of solid waste treatment, including municipal domestic waste, industrial waste, agricultural waste, etc.

7.Easy maintenance: The equipment structure is relatively simple and easy to repair and maintain, which reduces the maintenance cost of long-term operation.

8.Environmental performance: The dry sorting process does not produce wastewater, reducing environmental pollution problems and meeting environmental protection requirements.

9.Positive and negative pressure sorting technology: Some high-end wind sorting machines use positive pressure, negative pressure or a combination of the two to further improve the sorting accuracy, reduce dust generation and optimize the working environment.

Wind sorting technology is widely used in urban waste disposal, construction waste disposal, agricultural waste disposal and other fields. It is one of the important means to achieve resource recycling and environmental protection treatment.
