Air classifiers sort materials on an industrial scale by using a rising column of air to separate items based on density, size, and shape. They are used in industries such as recycling, food processing, and mining. Air classifiers can be purchased or leased and come in various sizes. They significantly reduce labor requirements and can be dangerous if not properly maintained.
An air classifier is a device that is used to sort materials on an industrial scale. The device is able to divide items with a high level of accuracy into a number of different categories. Air classifiers are used in materials processing in industries such as recycling, food processing and mining. These machines are mainly available through specialist companies and can be purchased or leased for various applications.
The air classifier takes advantage of a few simple physical aspects to operate. The device has a rising column of air, meeting a dry feed of items which are poured into the air classifier. Heavier items sink to the bottom of the column, while lighter items move to the top. This vertically separates the incoming flow of items. Each column layer can be dumped into a different container, keeping items separate.
Air classifiers can handle materials of various shapes and sizes. Density, size, and shape all play a role in where things will end up in the column. Operators can adjust the machines for different types of sorting applications and various screens and filters can be installed to facilitate sorting. These industrial sorters significantly reduce labor requirements by eliminating the need for manual processing of materials.
Companies can use air classifiers for tasks such as quality control, ensuring their products are very carefully sorted by size and weight. These devices can also prepare dry material streams for further processing, as seen in a recycling plant where the air classifier separates plastics, glass and other materials so they can be directed to different areas of the plant for further processing.
The size of an air classifier varies. Some models are quite small and designed to work with very small materials in settings such as laboratories. Others are extremely large and intended for factory floors. Companies that manufacture air classifiers also provide support in the form of parts and services for their products. Like other industrial equipment, these devices perform best when maintained in good working order and can be dangerous if improperly maintained or improperly installed.
Many businesses that need an air classifier purchase the product so they have it readily available. In case of temporary need, a rental or lease agreement can be arranged with an industrial equipment supplier or manufacturer. Rented devices may come with a technician to operate the equipment or instruct someone in its operation for safety.
