Description:  In Session 1 of Feeders 101 entitled “What is a Process Feeder?” Tom Rickenbach of K-Tron discusses key elements of process feeding.  Typical process feeders provide two modes of operation: Volumetric and Gravimetric along with continuous and batch feeding. Included are control strategies to feed product such as Proportional, Integral, Derivative controls, Weigh Belt Feeding and Loss-In-Weight Feeding.

A Proportional–Integral–Derivative controller (PID) is shown by use of diagrams and slides to analyze each type of action to achieve a controlled flow rate.  Along with this, Tom describes one type of flow sensor that employs the “coriolis” effect to provide a mass flow to a PID control loop as its’ feedback to compare to setpoint so that it may make adjustments in control as necessary to make sure the correct amount of product is flowing into the process line.

The operating principles of weigh belt feeding are demonstrated using a K-Tron feeder. Belt load times and belt speed are critical when using weigh belts.  Also, the operating principles of loss-in-weight feeding are also demonstrated using a K-Tron loss-in-weight feeder with color graphics.  As the name implies, a loss-in-weight feeder measures the loss in weight of product and controls discharge accordingly.

Finally, Tom discusses why it is important to understand feeder accuracy and how to test and verify that a scale is working properly. He concludes this session by discussing various application examples.
