The “Fluidized Bed” Operation for Mixing & Drying: Liquid dispersion is done by spraying The unique action created by the movement of liquids against fluidized powder, by the mixing elements produce intense but Top and / or Bottom Mounted Nozzles. gentle intermingling of the materials of the mix in a mechanically fluidized bed. The unique mixing action of the FKM series mixers is accomplished by a horizontal shaft which revolves at a high rate of speed rapidly projecting and hurling the mix materials away from the vessel wall into free space, filling the entire vessel. The mixing action causes the materials to crisscross in the direction of the vessel walls and inversely back again, providing a high volume rate of material transfer. The mechanically fluidized bed of particles is the basis of it´s mixing efficiency and accuracy, including mixtures with diverse specific gravities as well as other problems such as liquid incorporation and heat transfer. Mixing elements are designed to force the product into appropriate components of axial & radial motion. High-Speed Blending Choppers enhance mixing action by controlling particle size and trace ingredient dispersion, usually without the need for additional process steps. Chopper Action, sending fluidized particles upward, against sprayed liquids flowing in the opposite direction.

Drying Plastic Resins In The Littleford. 1.-High efficiency drying of Suspensions, pastes, and bulk materials. 2.-Fast drying cycles and discharge. 3.-Allows efficient drying of sensitive materials at low Temperatures. 4.-Complete dispersion of agglomerates, lumps and fiber bundles. 5.-Homogeneous mixing of dissimilar ingredients. 6.-Drying operations from liquid state to free-flowing powder in one vessel. 7.-Allows liquid addition during processing. 8.-Adapts itself to effective recovery of costly solvents. 9.-Eliminates need for additional processing equipment. The Key to this State-of-the Art drying technology is the unique, mechanically fluidized ploughshare action which agitates and individualize the solid particles to be dried. The ploughshare action forces the product into a 3-dimensions motion that individualizes each particle, continuosly exposing tremendous surface area for drying. The particles constantly contact one another, and the heated interior walls of the jacketed vessel furthering the drying process. Our dryers are also equipped with independently operated, high shear choppers, to reduce the particle size of the lumps or agglomerates, to expose undried materials and ensure thoroughly dried particle interior. Deagglomeration further shortens drying time. Heated Pulse Back Filter with Stack. Wet Product Condenser Littleford Dryer. Dry Product Recovery Tank. Vacuum Pump. Advance Drying: The Chopper Advantages in Drying: Fast, efficient drying without lump formation PASTE GRANULE POWDER M O I S T U R E Internal Drying without Choppers External Drying with Choppers DRYING TIME The action of the turbulent plows and the high shear choppers reduce the forming lumps to smaller granules, thus exposing large amounts of new surface area for drying. Reinforced Plastics Mix Includes: Thermoplastic Powders. Beads & Chopped Strand Fiberglass. Prior to extrusion or Injection molding, bundles of chopped strand fiberglass must be uniformly mixed with thermoplastic pellets, chips, beads or powder without filamentizing the fiberglass strands. The mechanically fluidized bed mixing action of the Littleford mixer separates the thermoplastic particles and gently blends in the fragile glass bundles. In a short mix cycle, often 15 to 30 Seconds, a 30% Glass Blend can be attained to an accuracy of less than 1.0%. There is no degradation of the fiberglass. The blend is discharged with the plows rotating to prevent stratification of the mixed materials. The very short mix cycles attainable in a Littleford Mixer enable more frequent batching. This means a reduction in capital investment by utilizing a smaller volume Littleford Mixer, rather than a large volume and long cycle time conventional mixer. Also, the Littleford mixer lends itself well to totally automated operation. Advantages: 1.- 30 Seconds Mix Cycles. 2.- No Filamentizing Of Glass Strands. 3.- No Stratification Of Discharged Product. 4.- Uniform Blend. Plasticized PVC Dry Blend Mix Includes: PVC Resin, Fillers, Pigments, Plasticizer, Stabilizer. “Dry Blends” of highly plasticized, filled, vinyl polymers and copolymers to be calendered into sheeting or flooring are prepared in the Littleford Mixer. For high volume applications, batches as large as 5,000 to 6,000 pounds can be prepared in very short mix cycles. These batch mixers are unexcelled as heat transfer vessels. (The mechanically fluidized bed mixing action creates tremendous particle surface exposure, which combined with constant movement, creates contact of all particles with the heat transfer surfaces.) Thus, completely jacketed mixing cylinders are able to transfer external heat to the product at extremely high rates. Due to the uniformity and temperature attained in the “Dry Blend”, the Banbury mix cycle is usually reduced. Banbury throughput increases of more than 10% have been reported. Finish product uniformity and quality has also been improved. Advantages: 1.- Highest Coefficient Of Heat Transfer. 2.- Low Horsepower Requirement. 3.- Thorough Plasticizer Absorption. 4.- Complete Product Uniformity. 5.- Large Batch Sizes. Reinforced Thermosets Mix Includes: Phenolic Resin, Wood Flour, Fibers, Pigments. Thermosetting molding compounds require high shear to disperse the pigments, fillers, and reinforcing fibers, plus exact temperature control to protect the resin. With conventional mixing equipment, pre-milling and post-milling operations are usually required. A uniform flow, labyrinth-design jacket surrounds the circumference of the Littleford mixer, thus providing exact temperature control. The unique mix action creates outstanding particle to heat transfer surface contact, resulting in an exceptionally high coefficient of heat transfer. The mixers, when equipped with high speed choppers, produce the high shearrequired to disperse and develop the pigment in a short mix cycle. Reinforcing fibers are dispersed uniformily without breakage or damage. Liquid additives can quickly be dispersed without agglomerate formation. Premilling of the batch components can be greatly reduced and postmilling and homogenization operations completely eliminated. Advantages: 1.- Short Mix Cycles. 2.- No Filamentation Of Fibers. 3.- No Stratification Of Discharged Product. 4.- Uniform Blend. Plastisols Mix Includes: Fine PVC Resin, Pigment, Plasticizer, Stabilizer. The unique plow-shaped design of the Littleford mixing tools creates a shear action which develops a suspension of extremely fine powdered PVC resins in plasticizers to produce agglomerate free plastisols. The mix cycles are very short, hence the plastisol is formed with little or no heat generation. The mixing action is so uniform that there is no tendency to form gels. In some cases, plastisols of lower viscosity require a higher degree of shear action. This can be provided in the Littleford mixer by equipping the unit with a high speed chopper located such that the mixing plows constantly bring fresh material into their path for effective dispersion. The mixer may be equipped for vacuum operation to permit the dynamic removal of entrained air from the plastisol. The mixing cylinder can also be completely jacketed to maintain optimum temperature for reactions, solvations and viscosity adjustments. Advantages: 1.- Short Mix Cycles. 2.- No Heat Generation. 3.- Thorough Dispersion, Usually Off The Hegeman Grind Gauge. 4.- Mixing And Deaeration In Same Littleford Mixer. Glass Reinforced Polyesters (BMC) Mix Includes: Catalysts, Chopped Strand Fiberglass, Pigments, Fillers, Polyester Resin. Compression molding compounds of fiberglass reinforced polyester resins can be quickly prepared in the Littleford mixer. The Littleford intermediate Intensity Mixer can produce a complete, quality molding compound of fiberglass reinforced Polyester resins in very little time without filamentizing the glass fibers. Fillers, pigments and catalysts can be homogeneously combined with the viscous Polyester Resins in very short mix cycles without the need for premixing the resins in a separate piece of equipment. Mixing one or two minutes after the addition of glass fibers causes all of the fiber bundles to be opened and uniformly coated with little or no fiber degradation. In addition to a reduction in process time and equipment, the physical properties of the final molded part are generally superior to those of parts produced by other methods. Advantages: 1.- Short Mix Cycles. 2.- Minimum Glass Degradation. 3.- Higher Physical Property Of Molded Parts. 4.- Lower Capital Cost Than Double Arm Mixers Sheet Molding Compounds (SMC) Mix Includes: Catalyst, Pigments, Fillers and Polyester Resin. Sheet molding compounds, although of various viscosities, are generally in the form of a paste. The Littleford intermediate Intensity Mixer rapidly disperses large quntities of fillers, pigments and other required additives into liquid resins to produce a homogeneous sheet molding compound. The general mixing procedure is to charge the liquid resins into the statc mixer, the catalyst and dispersing agent are added, followed by the addition of the filler, pigment and other ingredients. Throughout the process, exact batch temperature is controlled by utilizing a uniform flow heating/cooling jacket. The mixer can be equipped for the dynamic removal of all gases from the product. This is accomplished by mixing within a vacuum environment while simultaneously deaerating. This process substantially reduces the mix volume, resulting in a higher bulk density. Vacuum deaeration causes no appreciable increase in the mixing time required. Advantages: 1.- Short Mix Cycles. 2.- Complete And Rapid Dispersion. 3.- Easily Automated. 4.- No Heat Generation. Color Concentrates Mix Includes: Pigments, Lubricants, Beads or Pellets, Thermoplastic Powders. Surface coating alone is often inadequate for dispersing a high concentration of pigments and additives. The resin surface can not retain the concentrations required. High concentrations of pigment and additives must be driven into the thermoplastic resin with great force. When the point is reached where the resin particle contains the maximum amount of additives it can retain, higher concentrations can be achieved by a homogeneous blend of additive particles within the bed of enriched resin. The Littleford High Intensity Vertical Mixer is well suited for this application, with typical 1 to 2 minutes cycles. Its mix action creates an intensive impingement of lubricant, pigment and additives upon the resin particles in combination with thorough blending and complete breaking up of agglomerates of additives, as well as pigments. The cover is hydraucally operated, and when open exposes the entire mixer interior for easy cleaning between batches. Advantages: 1.- Short Mix Cycles. 2.- Uniform Surface Coating. 3.- Agglomerate Free. 4.- Easy To Clean. Plastic Powder Coatings Mix Includes: Pigments, Plastic Resins And Fillers. The preparation of plastic powder coatings requires a premix process where large resin flakes are broken down and uniformly dispersed with pigments and other additives. Following melt-extrusion and high energy milling, a flow agent must be precisely combined with the premix. The premix blend is prepared in a Littleford mixer. High speed choppers break down the large resin flakes as the plow action effects an intimate dispersion of pigments and additives. A cooling jacket allows exact temperature control. The flow agent is also applied in a Littleford mixer after milling the premix into a fine powder. The dual mix action provides the critical dispersion required, while the jacket maintains the desired temperature. Air seal prevent “hot” spots around the all high speed rotating shafts. Advantages: 1.- Rapid Deagglomeration Of Flake Resins. 2.- Pigments Rapidly And Thoroughly Dispersed. 3.- Short Mix Cycles. 4.- Uniform Dispersion Of Light Density Flow Agents. Drying Mix Includes: Plastic Resins. Drying, often important to the value and usefulness of many finished products, is of vital importance in the plastics industry. It is crucial to remove even trace amounts of moisture prior to final processing. The Littleford Mixer is an ideal Dryer. Individual particle separation is created by the unique dual mix action. The entire surface of each particle is exposed for drying continuously throughout the operation. When equipped with a heating jacket, drying results as each particle comes in contact with the heated jacket surface. For heat sensitive materials, warm dry air may be injected into the product at atmospheric pressure. The dry air absorbs misture and is removed from the unit, carrying the moisture with it. The Littleford Mixer, when equipped for vacuum operation, is capable of dynamically removing moisture within a short drying cycle. Vacuum operation also allows the removal and recovery of expensive solvents. Advantages: 1.- Excellent Heat Transfer Coefficients. 2.- Dry To Low Moisture Levels, Less Than .05% 3. Vacuum, Atmospheric Or Air Purge Operation. Surface Coating Mix Includes: Pigments, Lubricants, Thermoplastic Powders, Beads or Pellets. Thermoplastic resins in the form of pellets, beads, chip or powder, require the addition of pigments, lubricants and processing aids prior to final processing. This can be accomplished in a Littleford Mixer in a very short mix cycles, as low as 30 to 45 seconds. Blending & coating action is rapid, thorough and very gentle. The mechanically fluidized bed mix action exposes all product surfaces to assure complete uniformity of coating. The resultant short mix cycle enables to supply batch or continuous mixers. Continuous operation provides high output capacities at a modest capital investment. In applications where thermoplastic resin pellets are utilized, the gentle mixing action has a minimum tendency to gall the pellets. It lends itself well to blending ingredients having wide differences in size, such as pellets and pigments. Because each pellet receives a uniform surface film coating of lubricant, a consistent amount of dispersed pigments adheres to each pellet. Advantages: 1.- Short Mix Cycles. 30-45 Seconds. 2.- Uniform Surface Coating. 3.- Gentle Mix Action Without Product Degradation. 4.- Batch Or Continuous Mixer Application. Thermoplastic Resins Mix Includes: Polyethylene Or Polypropylene Resin, Trace Amounts Of Additive. To meet the special requirements of certain finished products, trace amounts of additives must be introduced and uniformly dispersed throughout thermoplastic resins. These processed resins are often produced in high volumes (2,500 to 50,000 Lbs/Hr). The Littleford intermediate intensity batch or continuous mixer, with it´s unique dual mix action, is capable of meeting these high volume demands with a minimum retention time. The accuracy of additive dispersion is often within 1% coefficient of variation. When equipped with a uniform flow cooling jacket, the Littleford batch or continuous mixer can eliminate conventional post-mix cooling equipment by simultaneously mixing and cooling. This is accomplished without any significant increase in mixing cycle time. For such an application, for example, The Littleford Model KM-3000 (53 cubic feet working capacity), would be capable of an aproximate throughput of 35,000 Lbs./Hr. Advantages: 1.- Short Mix Cycles. 2.- Uniform Additive Dispersion. 3.- High Volume Processing. 4.- Simultaneous Cooling. PVC: Compounding and Cooling. Mix Includes: PVC Resin, Pigment, Fillers Stabilizer, Modifiers. The Littleford PVC Processing system has been developed specifically to compound and cool polyvinyl chloride and similar materials. A vertical high shear, high intensity mixer has been matched and synchronized with a low intensity horizontal cooling unit that utilizes the mechanically fluidized bed mixing action to attain an extremely high degree of heat transfer. Littleford PVC processing system is a very compact installation with a wide range of output capacities.
