A new volumetric feeder for additive dispensing systems

By Chemical Engineering |

The new VMF-90D volumetric screw feeder (photo) is an automatic metering screw-feed system for mixing and dispensing dry materials into a secondary process. Among the standard features are a concentric material-conditioning overwind auger, an SCR controller that may be remotely mounted, a 4–20-mA integrated cycle timer, an alarm sensor and a vibratory agitator. Made of rugged, corrosion-resistant stainless steel, the feeder accurately dispenses most chemicals found in the water and wastewater industries at feedrates of 0.77 to 7.73 ft 3/h and with accuracy to within 1% of volume. — Scaletron Industries, Ltd., Plumsteadville, Pa.
