Small Feeders For Lightweight Materials From Eriez
June 12, 2004
Eriez has expanded its HD Series "High Deflection" Vibratory Feeder line to include two smaller drive units. The HD-26 & 36 size units are ideal for moving smaller volumes of powders and leafy products that are typically difficult to feed in an electromagnetic feeder. The HD Series "High Deflection" Vibratory Feeders combines the higher deflection (3/16") (4.8 mm) and lower frequency (30 cps) advantages of a mechanical feeder with the precise control of an electromagnetic vibratory feeder. Available in five models and 16 sizes, feed rates of up to 80 ft/min (80 m/min) are possible for products with bulk densities less than l0 lb/ft3 (160 kg/m3). All HD Feeders ship with a standard variable speed control housed in an M Type (NEMA 12) enclosure.
These High Deflection feeders incorporate Eriez' low energy AC electromagnetic drive with a patented armature design that reduces power consumption by 75% and creates an exceptionally powerful drive for its size. The elastomeric torsion spring provides quick stopping and protects the fiberglass springs from overstress damage. Trays are available in mild steel, stainless steel and in a wide variety of shapes and sizes.
