Littleford Bros. And J.H.Day The Ultimate
Combination
Whether it is heavy duty mastication, drying or
pharmaceutical granulation, our Double Arm
Mixers will make the difficult process
remarkably easier.
Available in both Tangential Overlapping
agitator actions
The J.H.Day Company pioneered and developed the
Double Arm Mixer and has applied its
extensive technology to a wide variety of
processes worldwide in the chemical, food,
pharmaceutical, plastic, ink and
colorants, rubber and adhesive industries.
Double Arm product viscosities can be
effectively and efficiently handled from
250,000 CPS to 5,000,000 CPS. Now fully
integrated into Littleford Day, engineering
enhancements have met the challenge of
desig- ning the industrys only true sanitary
Double Arms, including its proprietary sanitary
seal, in order to meet FDA, USDA and 3A
requirements. The Day Mougul Double Arm product
line features the unique tangential agitator
action in which the front agitator typica- lly
rotates 50 faster than the rear agitator.
This is ideally suited for heavy pastes
products that go through a solids/ liquids phase
of high viscosity that requires extreme
beating and high shear, although not at great
speeds.The Cincinnatus product line features
the overlapping agitator action in which
both agitators turn at the same speed, which is
ideally suited for dough-type or dough/paste
consistencies and phar- maceutical granulations.
Additional product ranges include snack
foods, canned meats,cake icings bakery
applications.

Mixtruders Designed to power mix and efficiently
discharge extremely difficult materials.
The Mixtruder is a Double Arm
Tangential action mixer with a forward and
reversing discharge extruder located in the
area of the bottom saddle of the vessel to
extrude tough to discharge pastes,doughs,gums,et
c. Its discharge capability allows it to
handle fibrous viscous materials such as
molding compounds in excess of 5,000,000
CPS. Tacky products such as high solids
cements and adhesives can easily be removed.
Used in a variety of sanitary applications such
as snack food doughs animal foods and chewing
gums. A further advantage of uniform
discharge is to facilitate the ability to
run downstream equipment on a semi-continuous
basis.
Vessel Options ASME Jacket to 200 PSIG Vacuum
design to 30 Internal Pressure Stainless Steels
Cored Blades for Heating or Cooling.
Variable Speed Drives available (including screw
discharge)
Optional Automated Cut-Off Blades/System to
size the extrudate for ease of handling.
The screw is run in the reverse direction while
mixing is taking place. This reverse action
allows material to be raised into the nip
or mix zone of the agitator. The screw, by
itself, is not a mixing tool. The screw
action, during mixing, however, enhances the
agitators mixing capabilities by moving the
product in an upward motion. When the screw is
moved to the forward or discharge direction,
product is extruded from the bowl. Discharge
is governed by the size speed of the screw.

Tangential
Overlapping
In this design, the agitators rotate in
the troughs of the tank, meeting
tangentially just above the saddle. The front
agitator rotates faster than the rear,
usually in the ratio of 3 to 2. Materials
that are fed in sheets or chunks or otherwise
have a tendency to ride on top of the
agitators lend themselves to tangential
agitator action. The larger nip between the
agita- tor and the variation in speed pulls
the materials into them for effective
disper- sion. These are generally used for
mate- rials of heavier viscosities such as
adhe- sives, polyester pre-mixes, flush
colors brake linings.
In the overlapping design, the agitators
overlap just above the saddle of the tank.
Due to this, both agitators rotate at the
same speed. Materials that flow freely or
creep down into the agita- tors lend
themselves to this old design, which
offers a faster interchange of all
materials for smooth dispersions. Overlapping
agitator action is generally used on
materials of lighter viscosities such as
pigments, clay coatings, creams ointments.

Littleford Day Sanitary Seals Littleford
Day Sanitary Double Arms offer a wide range of
shaft seals
Our sanitary knockdown seals offer the most
versatility of any of our shaft
seal arrangements. Tools are not needed
for seal removal. These segmented seals
in- clude Teflon solid type, split ring
packing arranged on a pull-apart gland. After a
process (such as granulation) is complete, it
is simple a matter to pull the shaft seals
apart and wash down the enti- re mixer between
batches. This eliminates time consuming
repacking of standard rope type packing
glands. This special sanitary seal is also used
in conjunction with vacuum
requirements. Littleford Day stuffing boxes are
encap- sulation designed. By
designing the stuffing box for vacuum, we can
utilize the knockdown seal arrangement for
the shafts and allow for equal pressure
across the entire mixer. Both the tank and
its external stuffing boxes are set for
vacuum operation in this manner. This
advances are particularly suitable for sanitary
opera- tions requiring both granulation
drying. Vacuum design stuffing boxes are
also available for use in conjunction with
sanita- ry seals and vacuum design mixing bowls.

Laboratory Double Arm Mixers Available
in both tangential (Mogul) overlapping
(Cincinnatus) design.
Laboratory and pilot plant Double Arms range
in size from 1 quart to 10 gallon working
capacity. All Littleford Day laboratory
units are free-standing in design and can
be equipped with any feature(s) available
on the larger units. Available in both
tangential and over- lapping design, the
Littleford Day Double Arms can be equipped for
vacuum opera- tion with full ASME jacketing for
cooling or heating,variable speed drives a
host of sanitary features including complete
stainless steel construction in compliance with
FDA, USDA and 3A requirements. Wheter it
is to be utilized as a tool for re- search and
development, product formu- lation or direct
production scale-up, our Laboratory Double
Arms will meet the most stringent of process
requirements while yielding the highest degree
of accuracy quality.
