Automatic Metering Screw Feed System for Mixing and Dispensing Dry Polymers into A Secondary Process

The Model VMF-90D Volumetric Screw Feeder with Vibratory Agitator has been designed to be an “off the shelf” option for upgrading or replacing existing volumetric feeding units. The VMF-90D is capable of accurately dispensing many common chemicals found in the water and waste water industries, as well as, a host of other industrial chemicals. Scaletron decided to offer many optional features as standard equipment on the VMF-90D so that one feeder can be adapted to many systems. Features like a concentric material conditioning overwind auger, remote location mountable SCR controller, 4-20mA output, integrated cycle timer, LIW recording with scale, alarm sensor and a vibratory agitator.
