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.
Lecture includes downloadable class notes and
a self administered quiz with answer sheet. The seven-day subscription
