Van Tongeren America, a process equipment manufacturer based in Lebanon, Pennsylvania, released its gravitational-inertial classifier (GIC) system that automatically separates dry materials without using water.

Developed to replace the traditional wet separation process, the pneumatic air classifier system harnesses gravitational, inertial, centrifugal and aerodynamic forces simultaneously to separate particles at any cut point from 300 μm to 63 μm (50 to 230 mesh), according to the company.

The GIC system passes a current of air through a curtain of falling material, then directs each particle towards a series of vanes where coarse particles are discharged and entrained fine particles are recirculated in an eddy current until discharged and captured by a dust collector.

Additionally, the GIC system is designed with no moving parts for dependable service and is ideal for classifying manufactured sand, frac sand, crushed stone, cement, salt, lime, soda ash, and a variety of aggregate and minerals, according to the company.
