MINIMUM SPEED:
Slowest Speed at which Centrifugal Discharge
will occur.
OPTIMUM SPEED:
Speed at which most desirable results are
obtained.
MAXIMUM SPEED:
Maximum Speed is governed by many factors
including Bonnet Shape, clearances, throat
location, desired capacity and commodity
elevated, therefore is not published
This table is for general reference only and
does not guarantee perfect discharge for all
bucket elevators at all speeds shown within
speed range. Note: Hy-Pro Elevator Buckets
spaced on minimum centers may require faster
minimum speeds than shown on this chart.
The optimum speeds shown are based on free
flowing whole grains. The optimum recommended
speed for feed ingredients and other similar
materials is 85% of the optimum speed shown.
*NOTE: HY-PRO BUCKETS MAY REQUIRE FASTER
MINIMUM SPEEDS THAN SHOWN ON THIS CHART AT
MINIMUM SPACING. |
