The VBC operates using vertically oriented blades alongside a dynamic separator rotor. Together, they generate a controlled internal air vortex. This spinning action throws heavy, coarse particles outward to the perimeter via centrifugal force, causing the oversized particles to drop back down into the grinding circuit. Fine particles that successfully pass through the rotor are carried out to a cyclone or bag filter.
Operators can easily adjust the separator rotor’s rotational speed to precisely target finished particle sizes ranging anywhere from 5 to 250 microns. VBC technology can be integrated directly into any standard airswept mill system or utilized in the Bradley Windsifter—a stand-alone unit that classifies independent streams of fine and coarse material.
