	All Metalfab Volumetric Screw Feeders feature Metalfab’s rugged design and unique agitator/conditioner screw. In operation, the agitator/conditioner screw begins to move materials forward in the feeder’s trough. Since the agitator/ conditioner screws are larger in diameter than the metering (feeding) screw and of wire configuration, they carry a greater capacity than the metering screw, allowing material to flow through and around it. This 360° influence of material forces entrained air up and out of the metering area and force feeds material into the flights of the metering screw to ensure they are completely full with uniformly dense material.
