short pitch
double flight
•
Most common type of material feeder
•
Short pitch and/or double flight screws are
preferred. They reduce the batch size (and
increase the frequency) of the material
discharge pulses. Alternatively, the flights of a
standard screw may be cut back, ending before
the discharge opening.
•
A reverse flowguide transition should be
considered for variable operating speeds or
constant speeds above 40 rpm.
•
Provides an air seal between the upstream and/or
downstream process, and the flowmeter
•
Required when the material is pneumatically
conveyed or flowmeter/process isolation is
required.
•
Use a reverse flowguide transition for variable
operating speeds or constant speeds above 10
rpm.
•
Common to grain applications
•
Slow elevators (typically chain drive) often
produce heavily pulsing material discharge,
requiring feeder discharge damping. Generally not
suitable for the Millflo.
•
Fast elevators (typically reinforced belt drive) often
require a deadbox to reduce material velocity. High
frequency of pulses make it suitable for the Millflo.
•
Conveyor belts generally produce a non-pulsing
material discharge, ideal for flowmeter operation.
•
A reverse flowguide transition (and/or material
discharge baffle) is often required for variable belt
speeds or constant speeds in excess of 1 m/s (200
feet/minute).
