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 industry´s 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. Sanitary Stainless Steel Construction Custom polishes from 120 Grit to mirror finishes. E-Z Clean “encapsulated” stuffing boxes. Vacuum domed lids. ASME certified heat transfer jackets to 200 PSIG Variable speed. Spray bars for cleaning. Sanitary “knockdown” seals. Single base design.

Mixtruders Designed to power mix and efficiently discharge extremely difficult materials. 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. 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,etc. It´s 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. 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 agitator´s 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 or Overlapping. Our Blades Blade Types Sigma: Best for all around uses. 135° Spiral: For larger overlap- ping type mixers. 180° Spiral: For fiber reinforced products & lower shear. Double Nobben: For extra shear. Serrated: For tearing action & get “grip”. Replacea- ble shoes available. 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 Tank Head Plate End Plate Split Stuffing Box Tank Head Hand Knob Agitator Shaft Aligning Dowel Stud Bronze Split Sleeve Split Chevron Packing Rings Stuffing Box Plate 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 it´s 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.
OSHA approved guards for moving parts. Totally enclosed heavy duty gear boxes. Cover designed for atmospheric or Full Vacuum. Drives avai- lable in one or variable speed. Custom stands Mfrd. to customer Specs. Motorized Tilt Bowl Operation 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.
