The Blue River 3.0 Hopper/Feeder Assembly is designed to precisely meter out polymer from the
hopper into a transfer chamber located directly under the feeder. The feeder utilizes a slotted
rotor turned by an AC or DC driver gear motor. This arrangement provides a uniform and precise
feed rate into the polymer conveyance stream.
-
Feeders are available with a 17, 22 and 33 RPM AC drive motor or can be equipped with a 0-25 RPM
variable speed DC motor. A variety of rotor sizes are available to allow feeder discharge
rates of 0-125 cubic inches of material per minute.
-
The hopper will hold approx 3 cubic feet of material. Hoppers are fabricated
from 16 ga. 304 Stainless Steel. The Enclosure is also 16 ga. Stainless Steel and is fitted
with a hinged and latched door at the front of the hopper. The hopper includes a removable
trash screen and the lid is hinged, latched and includes a gasket. Side panels can be
removed for service. The hopper is isolated from the enclosure frame with rubber bushings to
provide maximum efficiency for the vibrator.
-
The hopper is fitted with and electric vibrator wired to run whenever the feeder motor is
operating.
-
Lighting is provided inside the enclosure. These lamps also provide heat to reduce
problems with humidity.
-
A slide valve is fixed under the hopper between the hopper and the feeder to facilitate
service of the feeder assembly.
-
The transfer chamber is manufactured with a clear acrylic chamber to allow visual inspection for
any buildup or plugging. The lower housing of the chamber is equipped with two stainless steel
latches to allow easy cleaning or inspection.
-
The optional proximity switches located inside the hopper and transfer chamber will trigger an
alarm condition in the event of an out of polymer or plugged transfer chamber condition.
-
Outside dimensions: 22 1/4 x 28 1/4 x 40 3/4 high
