The VMF-90D volumetric screw feeder from Scaletron Industries is an automatic, metering screw-feed system for mixing and dispensing dry materials into a secondary process. Functionality that previously was available only as options is included, resulting in a feeder that is operationally robust, versatile and installs quickly into a wide range of additive metering systems. Made of rugged, corrosion-resistant stainless steel, the feeder is designed for use in water, wastewater and chemical processing applications. It dispenses at feed rates of 0.77 to 7.73 cubic feet per hour, with accuracy to within 1.0 percent of volume. The built-in, 1.5 cubic foot, gravity-fed hopper is fed via a stainless steel, 1.5-inch (38.1-mm) diameter, open helix feed-screw. The hopper features a maintenance access hatch and an integrated load-cell attachment point.
