Gravimetric Blender
The ProRate gravimetric blender
handles pellets, regrind, and raw
materials. Consisting of one to
eight feeders and a central microprocessor-based controller, it is
designed to continuously meter
raw materials accurately into a central station hopper. Each feeder oper -
ates in an independent, continuous
loss-in-weight scaling mode to ensure
the accuracy of each ingredient. The
desired feed rate for each material can
be entered as pounds or kilograms per
hour, as a percent of the total rate, or
as a percent of the virgin material. The
controller continuously monitors the
weight signals of each feeder and adjusts the
auger speed to match the recipe feed rate for each feeder. Augers are
available in five interchangeable sizes. The microprocessor controller runs
from one to eight feeders simultaneously, providing a capacity range from
1 to 80,000 lb/hr.

Tri-mix turbo-shear agitation combines scrape-surface motion with high
shear. The counterrotating scrape-surface agitator can be designed for
up to 2 million–cP products, while the
turbo-shear head has been modified
to accept several disperser designs
for 10,000-cP products alone or up to
50,000-cP products with the aid of the
counterrotating agitator. This agitator,
combined with the vessel’s vacuum/
pressure rating, gives the unit versatility. Application engineers can
design a lab unit for specific
process requirements.

Mixers and Blenders
Gardner mixers and blenders feature an easy-clean cantilever
shaft. Available in various designs with a choice of plough,
paddle, or interrupted spiral agitator, the large top and
end door allow for trouble-free cleaning and inspection.
Completely contained mixing media provide a hygienic environment for dry, semidry, or moist powder applications.

Blender Conveyors
Stationary and portable CB-series blender conveyors
combine bulk carrier unloading, transfer, and blending
capabilities in one vacuum-pressure unit. They are sized
for 5 to 20-plus tn/hr and can
handle powdered, granular, or
pelletized friable abrasive materials. Equipped with automated controls and
load cells, these machines blend products from multiple
sources and convey them to one or
more destinations using
a single 15-psig positive-displacement blower. A
proprietary semidense
design results in low
line velocities and high
material-to-air ratios
that reduce wear and
product degradation.

Powder Induction System
Mixing powders into liquids, the Fastfeed
powder induction system offers consistent powder delivery even as viscosity
and solids levels increase, ensuring that
the system will never plug or foul. It
offers the benefits of an in-line, skid-mounted dispersion system that feeds
powders and disperses them instantly.
The unit can deliver powder in-line
at controlled feed rates from 3 to 200
lb/min. It allows processors to add dry
ingredients to mix vessels in a more
ergonomic fashion than other systems,
reducing operator injuries and providing
the shear required for ever-changing and
ever-tougher ingredients.

Fluidized Zone Mixer
The Bella fluidized zone mixer
achieves fast, high-capacity, low-shear,
precision mixing of either dry bulk
solids or liquids with solids. Regardless
of particle size, shape, or density,
materials are mixed with a fast, efficient, and gentle action, with typical
mixing times of 60 seconds or less. A
weightless zone created by low-speed
counter rotating shafts generates low
friction without shear, making the
mixer ideal for fragile products that
cannot tolerate rough handling. Even
flakes or spray-dried bodies remain
intact. The Bella XN mixer includes
twin bomb-bay door openings for fast,
efficient discharging and for minimizing segregation during discharge. The
Bella mixer is available in stainless
steel for sanitary applications. Custom
sizes, finishes, and construction materials are available.
