A screw feeder is a versatile, compact and economical metering device for powder bulk solids. What distinguishes a screw conveyor from a screw feeder? A screw feeder is used to meter, or set the flow rate, to other pieces of conveying and process equipment from a hopper, silo or bulk bag. The inlet of a screw feeder, whether square, rectangular or round is flooded with bulk material at all times and therefor has to be specifically designed for this condition. The distance between the flights (pitch), diameter and speed (RPM) of the screw feeder determine how much bulk material is fed out of the bin over time and can be adjusted by varying any of these parameters. Screw feeders meter product by volume and are often referred to as volumetric feeders.

A screw feeder is the most versatile and customizable bulk material metering solution available. With a wide ranges of standardized and stocked components, screw feeders can be easily and affordably customized to fit any application. Even completely custom solutions are standardized for ease of manufacturing, assembly and maintenance. Screw feeders can be designed to be horizontal or inclined and are specifically matched in size, speed and horsepower to the application. Screw feeders also offer the benefit of being completely enclosed for dust/vapor containment and safety. Since a screw feeder is completely enclosed with only a smooth low speed shaft exposed the risk to operators is very low. Even the shafts can be covered to offer a completely enclosed and worry free solution. Screw feeders can be manufactured in a wide variety of materials with carbon steel being the most common. Other materials of construction include 304 stainless steel, 316 stainless steel, T1 steel, abrasion resistant steel and even exotic alloys like duplex stainless steel and titanium.
