Van Tongeren America, a process equipment manufacturer, unveiled a line of classifier systems that collect and separate dry particles by size range using only ambient air and gravity.

According to the company, the Van Tongeren air classifier systems eliminate the use of water, allowing the material to be kept dry upstream and downstream while replacing wet processing with an environmentally responsible dry processing approach that conserves water. The needs for wastewater management and drying equipment for moisture removal are eliminated while worker safety is improved, efficiency is streamlined and product quality is consistently assured, the company says.

The classifier systems are ideal for manufactured sand, aggregate and other minerals and materials used in a 24/7 operation, according to the company.

Van Tongeren’s classifier line is comprised of three different models using three different classification methods, all custom designed and engineered based on the application to meet specific production goals and end product specifications. 

The gravitational classifier operates without moving parts for low maintenance, the company says, and separates fines less than 150 mesh to 150 µm from more coarse material. Additionally, the gravitational-inertial classifier separates fines from 300 µm to 36 µm and the centrifugal classifier separates fines from 100 µm to 15 µm.

The classifiers may also be used in series to split feed multiple products at different cut points, and often include a cyclone or bag house dust collector to meet air pollution control requirements, according to the company.
