An Air Classifier is a device used to separate particles based on their size and density using air flow. It works by creating a controlled air stream that lifts lighter particles while allowing heavier ones to fall. This process is commonly used in industries such as mining, recycling, and food processing to improve product quality and efficiency. These classifiers can be adjusted to target specific particle sizes, making them versatile for various applications. They are often used in conjunction with other equipment, such as sieving machines and cyclones, to enhance the overall separation process and achieve desired material specifications.
