VIBRATING FEEDER
Vibratory feeders are used in gravimetric feeding systems to handle solids with particles that are loo large to be handled by screw, rotary-vane, or vertical-gate feeders, or in operations where the physical characteristics of the solid particles would be adversely affected by passage through these volumetric feeding devices. The discharge …

How to Select a Rotary Airlock
In this application, a 12" airlock at 14 RPM or a 14" airlock at 9 RPM will work. The larger 14" airlock would permit better mass flow of product whereas the 12" airlock might be selected based on economy, smaller height/ footprint, and higher operating speed. Note: For feeding applications, 10-15 RPM typically provides the most uniform ...

As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (e.g., cu. ft./hr.). The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the other hand, modulates the mass flow rate. This can be done either on a continuous basis (the feeder
