Model 3206 Dry Powder Mixer
400-800 pound batches
The Model 3206 KELLY DUPLEX Horizontal Mixer is designed
to specifically address production requirements and concerns experienced
by operators in the Rotational Molding Industry
This mixer provides for easy access for cleaning and
loading. The standard full open top cover gives complete access to the
interior. Cover features include an air vent with dust control sock, a
material inlet nozzle and a color additive port. The cover is hinged,
gasketed and clamped with easy to use quick acting clamps. Continuously
welded mixer body seams and tool arms eliminate hard-to-clean
contamination points. Air purged shaft seals help to prevent cross-batch
color contamination. An optional air control system provides regulated,
filtered, and dried air to the shaft seals and discharge gate pocket when
the mixer is operating and shuts off the air supply when the mixer is not
The Model 3206 is constructed with a stainless steel
body and endplates to promote quick, efficient, and inexpensive cleaning
and to minimize static, without the greater expense of total stainless
steel construction. Optional internal metal surface polishing further
enhances this quick cleaning design.
A combination of curved paddle and plow mixing tools
create a scooping and lifting mixing action, with a unique "criss-cross"
blending pattern. This positive and thorough action assures that all
material is continuously overlapped and cross-blended for uniform product
dispersion throughout the batch.
A packed air operated knife gate discharge valve
provides for a tight mixer vessel and allows for a thorough discharge.
Valve uses a metal-to-metal stainless steel seat for positive shut-off and
Drive horsepower and final driven speeds have been
engineered for dispersion of 400-800 pound batches of polyethylene of
various densities, from 22 to 35 PCF, with from 0.1% to 1% of dry color
pigments. An optional transfluid hydrokinetic transmission can be built
into the drive to provide smooth and gradual starts and protection against
An optional Motor Control Center provides for the
control of all mixing functions, and can include a batch cycle timer, a
temperature indicator, a mixer motor jog function, indicating lights and a
remote operator station.
Mixer support legs are furnished to provide discharge
heights sufficient for discharge directly into bulk containers. Optional
load cells are available so that entire mixer is scale mounted right on
the production floor.

Model 3206 Mixer rendering illustrates a 30 HP drive
equipped with a transfluid hydrokinetic transmission operating the mixer
shaft at 150 RPM. This drive provides for starting the mixer after the
batch has been weighed and loaded by the integrated load cell scale
system. Other visible features include the packed and air purged shaft
seal system, the gasketed, clamped and hinged full open top cover with a
built in color additive panel, a bulk loading inlet nozzle and a mixer
filtered air vent.

packed air cylinder operated knife gate discharge valve, which provides
for a tight mixer and allows for a thorough discharge. The mixer support
legs provide for direct discharge into bulk containers, and the leg pads
interface directly with an integrated load cell batch weighing system.
