Densifying screw feeder
The Diamondback Technology densifying screw feeder easily retrofits existing bins to eliminate flooding, flushing and erratic flow while providing excellent anti-arching capabilities. The screw seals against flushing and densifies powders, removing unwanted air for sack or bag filling. It also provides a controlled uniform density for weigh hopper applications. The screw comes with a variable speed that accommodates both fast and dribble feed conditions. It also handles extremely cohesive bulk materials at consistent output densities.
Typical applications
- Eliminating flushing and erratic flow from existing bins
- Controlling multiple feed rates to weigh hoppers
- Sealing against pressures and vacuum
- Prefeeding rotary valves to eliminate leakage effects
- Densifying powders before packaging or bag filling
- Handling cohesive bulk materials at consistent output densities without hangups
Features
- Anti-arching capabilities equivalent to a conical hopper outlet more than three times the screw's diameter
- Wear-resistant steel coating on key flight areas
- Removable screw and assembly for easy repairs and maintenance
- Adjustable flow pattern control for field adjustments
- Extra mating flanges for easy retrofitting
- Cantilevered screw to reduce bearing and seal problems
- Available in 6-, 12- and 18-inch diameters
