The Volumetric Feeder is a simple, economical feeding solution for applications that do not require a high degree of feed rate accuracy. Volumetric feeders are also frequently employed in gain-in-weight batch operations.
Screw feeders are the most common and economical volumetric feeders you can buy. Powerlion makes both single screw and twin screw volumetric feeders in a wide range of sizes to meet your feed rate requirements and solve your material handling problems. Some are optimized for quick material changes and can even be configured for differing material properties. Others feature easy cleanability and meet food and pharmaceutical sanitary requirements.



Technical Parameters:

Principle of operation:
Accurate metering of bulk solids is achieved using a spiral helix, screw, rotary valve, rotating agitator, vibrating tray or cylindrical stator. Even in the volumetric mode, the feedrate remains constant under the condition of a repeatable fill level and an even bulk density of the powder which provides a continuous filling degree of the metering helix. 
Important parameters for a precise dosing:
1. Uniform subsequent flow in the hopper by means of agitator and adapted auger shape
2.  Uniform bulk density and feeding in helix and screw by using intromitters.
3. Correct selection of the auger and metering tube
A linear volumetric feeder is also a prerequisite for a good gravimetric feeding.
