Air Separator is a mechanical device that separates materials based on aerodynamic principles. It is widely used in resource recycling, agricultural processing, industrial production and other fields.

The core working principle of the air separator is to use the difference in the force exerted on different materials in the airflow to achieve particle separation. When the equipment is running, the fan generates a directional airflow. After the sorted materials enter the sorting chamber, due to the differences in density, particle size and shape, the balance state between the airflow force exerted on each material particle and its own gravity is also different. Lightweight materials with low density and large volume (such as plastic film and paper) will move farther along the airflow direction under the push of the airflow; while heavy materials with high density and small volume (such as metal, glass and stone) will settle quickly due to the dominant gravity. By reasonably designing the structure of the sorting chamber and the airflow parameters, materials with different characteristics can be accurately separated and collected at their corresponding outlets.

In terms of application, the air separator performs very well. In garbage sorting, it can separate recyclables such as plastics and paper from kitchen waste, bricks and stones in mixed garbage, thereby improving resource recycling rate; in the grain processing industry, it can remove light impurities and deflated grains in grains to improve product quality; in the field of waste plastic recycling, it can separate plastics of different densities to provide pure raw materials for subsequent recycling.

Air sorting machines have many advantages. First, the equipment structure is relatively simple, mainly consisting of a fan, a sorting chamber, a feeding device, a discharging system, etc., without complex and precise components, so installation, operation and maintenance are relatively convenient, reducing the threshold for use and operating costs. Second, the sorting process is green and environmentally friendly, does not require the addition of chemical agents, does not pollute the environment, and can effectively realize the recycling of resources, which is in line with the concept of sustainable development. Third, it has strong adaptability. By adjusting parameters such as air flow velocity and sorting chamber structure, it can process a variety of different types of materials to meet the diverse needs of different industries and different production scenarios. In addition, the air separator can also be combined with crushers, screens, magnetic separators and other equipment to build a complete material processing production line, further improving processing efficiency and sorting effects.

Air Separator is a mechanical device based on aerodynamic principles that uses the force difference of materials in the airflow to achieve separation. It is widely used in resource recycling, mineral processing, agriculture and other fields. Its core principle is to effectively separate mixed materials through the action of airflow according to the density, particle size, shape and air resistance of the materials.

The basic workflow of Air Separator revolves around the generation and control of airflow. The equipment is mainly composed of key parts such as the feeding system, sorting chamber, fan, airflow adjustment device and discharge port. The mixed materials to be sorted are evenly transported to the sorting chamber through the feeding system. At the same time, the fan generates a high-speed and stable airflow, which enters the sorting chamber after being optimized by the airflow adjustment device. In the sorting chamber, the airflow forms a specific flow field, in which the mixed materials are subjected to the combined action of multiple forces such as gravity, airflow thrust, air buoyancy and air resistance.

Materials with low density, fine particle size and flat shape, such as waste paper, plastic film, lightweight fiber, etc., are subject to greater air resistance and are easily suspended and carried by the airflow under the action of airflow, moving in the direction of airflow, and finally discharged from the light material outlet near the airflow outlet; while materials with high density, coarse particle size and regular shape, such as metal blocks, glass, sand and gravel, are subject to insufficient air resistance to suspend them due to their own gravity and inertia, and sink rapidly under the action of gravity and are discharged from the heavy material outlet at the bottom of the sorting chamber.

Some Air Separators will also set up multi-stage sorting structures to achieve more refined material separation by adjusting the airflow speed and direction at different stages. For example, in the secondary sorting stage, slightly heavier materials mixed in light materials can be further separated, or particles with relatively small density can be screened out from heavy materials, greatly improving the sorting accuracy of materials. In addition, some advanced Air Separators are equipped with intelligent control systems that can adjust airflow parameters in real time according to material characteristics to ensure the best sorting effect under different working conditions.

Air Separator, with its unique working principle, can efficiently separate mixed materials without complicated chemical treatment or high-energy mechanical operation. It plays an important role in resource recycling and material pretreatment, laying a solid foundation for subsequent processing and resource regeneration.

Air Separator is an efficient equipment based on aerodynamic principles, which uses airflow to generate differentiated forces on materials of different densities and particle sizes to achieve material separation. With its unique technical principles and design, it has shown significant characteristics and advantages in the fields of resource recycling and industrial production.

1. High efficiency and precision to improve separation quality

Air Separator can efficiently separate materials according to their density, shape, particle size and other characteristics by precisely controlling the speed, direction and intensity of the airflow. In the process of recycling waste plastics, it can quickly separate plastics of different densities with a purity of more than 90%; when processing domestic waste, it can effectively separate light paper and film from heavier masonry and metal, greatly improving the sorting efficiency and quality, and laying a solid foundation for subsequent resource utilization.

2. Widely applicable to meet diverse needs
