Introduction and application of air classifier

1).Air classifier (also called wind classifier or airflow classifier) is a mechanical device that uses aerodynamic principles to separate materials of different densities. It is particularly important in the waste recycling industry and is often used to separate light and heavy components from mixed materials. The following is a basic introduction to air classifiers and an overview of their working principles and technical features.

2).Working principle of air classifier:

Air classifiers separate materials by controlling wind speed and wind direction. Its basic workflow is as follows:

1.Feeding: The mixed material enters the feed port of the air classifier.

2.Wind force regulation: Adjust the speed of the fan and the design of the air duct according to the different material characteristics (such as density, shape, size) to be separated.

3.Separation: Lighter materials will be carried away by the air flow and collected in the light area; while heavier materials will continue to fall due to gravity and eventually be collected in the heavy area.

4.Collection: The separated materials enter different collection areas respectively, thereby achieving effective classification of materials.

3).Technical features and application areas:

1.High efficiency and energy saving: Compared with other physical separation methods, air separation technology has relatively low energy consumption.

2.High flexibility: The wind speed and duct structure can be adjusted to meet the needs of different types of material separation.

3.High degree of automation: Modern air separators are usually equipped with automatic control systems, which can achieve continuous operation and reduce manual intervention.

Environmental protection: It helps to reduce the amount of landfill, promote the recycling of resources, and meet environmental protection requirements.

4).Application scenarios:

Air separators are widely used in various material separation occasions, especially in the waste recycling industry:

1.Municipal domestic waste (MSW) treatment: used to separate different materials such as paper, plastic, metal, glass, etc.

2.Construction waste treatment: Separate lightweight materials such as wood chips and foam in concrete and bricks.

3.Agricultural waste treatment: For example, grain screening to remove impurities in grains.

5).Design and manufacturing points:

1.Duct design: Reasonable duct design is the key to ensure the separation effect, and accurate calculation of wind speed and air volume is required.

2.Fan selection: Select the appropriate fan type and specifications to meet the wind force requirements under different working conditions.

3.Material property research: In-depth understanding of the physical properties of the target separation material in order to optimize equipment parameters.

4.Maintenance convenience: Design a structure that is easy to maintain and clean, reducing downtime and maintenance costs.

As a manufacturer, when designing and manufacturing air winnowing machines, we should also pay attention to the safety performance, reliability and economy of the equipment, while complying with the standards and specifications of the relevant industry. I hope this information can help you better understand and design air windowing machines. If you have further technical questions or specific needs, please continue to ask questions.
