FREQUENTLY ASKED QUESTIONS (FAQs)
- What is the Littleford Model KM-3000-D plow mixer used for?
The Littleford KM-3000-D is an industrial plow-style batch mixer designed for high-intensity mixing of compatible powders, granules and dry bulk solids. Potential applications include specialty chemical blending, mineral powder processing, detergent manufacturing, fertilizer production, construction material mixing and other industrial powder formulations.
- What is the working capacity of the Littleford KM-3000-D?
The mixer has an approximate working capacity of 74 cubic feet. Actual allowable batch weight depends on material bulk density, filling level, mixing characteristics and the manufacturer's recommended operating limits.
- What is the difference between working capacity and total chamber volume?
Working capacity represents the approximate volume of material intended to be processed during operation. Total chamber volume is the internal volume of the mixing vessel. The working capacity is generally lower to provide space for product movement and proper mixing action. This unit has a stated working capacity of approximately 74 cubic feet.
- How does an industrial plow mixer operate?
A plow mixer uses mixing elements mounted on a rotating horizontal shaft to move material throughout the mixing chamber. The agitation produces continuous product movement and helps distribute ingredients within the batch. Mixing performance depends on paddle configuration, shaft speed, material characteristics and fill level.
- What is the difference between a plow mixer and a ribbon blender?
A plow mixer uses plow-shaped or paddle-style elements to create intensive material movement and distribution throughout the mixing chamber. A ribbon blender uses inner and outer helical ribbons to move material in opposing axial directions. Plow mixers are often selected for applications requiring intensive powder mixing, dispersion or specialized processing, while ribbon blenders are commonly used for bulk powder blending.
- What materials are used in the construction of this Littleford mixer?
The mixing chamber and jacket are constructed of 304 stainless steel. This material is commonly used in industrial processing equipment and provides corrosion resistance for many compatible manufacturing applications. Suitability for specific chemicals should be confirmed.
- Is the Littleford KM-3000-D jacketed?
Yes. The mixer includes a 304 stainless steel jacket rated for 75 psi at temperatures ranging from 32°F to 320°F. The jacket may be used for compatible heating or cooling applications when properly connected to an appropriate temperature control system.
- Can the mixing chamber operate under pressure or vacuum?
The mixing chamber is rated for atmospheric operation. The 75 psi pressure rating applies to the jacket, not the internal mixing chamber. Pressure or vacuum processing should not be assumed to be supported without additional engineering verification.
- What is the purpose of the jacket on this plow mixer?
The jacket provides a means of transferring heat to or from the mixing chamber using a compatible heating or cooling medium. This may support temperature-controlled blending, product conditioning or specialized thermal processing applications.
- What is the main motor horsepower?
The mixer is equipped with a 100 HP motor rated at 1,780 RPM. The motor requires 460-volt, 3-phase, 60 Hz electrical service and drives the main mixing shaft through a Falk gearbox.
- What gearbox is installed on this mixer?
The unit includes a Falk gearbox with a 13.86:1 reduction ratio. The gearbox reduces the motor's rotational speed and transmits torque to the mixing shaft. Actual shaft speed should be confirmed against the complete drive configuration.
- How many mixing paddles does the unit have?
The machine features an approximately 5" diameter shaft with 12 welded mixing paddles. These paddles provide the mechanical agitation required for mixing compatible bulk solids within the chamber.
- Does this Littleford plow mixer include high-speed choppers?
The provided specifications identify provisions for 10 tulip-style choppers, each specified for a 15 HP drive motor, along with five additional chopper provisions. The description does not confirm that the chopper assemblies or their motors are installed or included. Buyers should verify the installed equipment and available components.
- What is the purpose of high-speed choppers in a plow mixer?
High-speed choppers are commonly used in intensive mixing systems to assist with breaking up agglomerates, dispersing minor ingredients and supporting certain granulation processes. Their effectiveness depends on product characteristics, operating speed, chopper design and mixing conditions.
- Can this mixer be used for granulation?
The machine may be suitable for compatible granulation processes, particularly when equipped with appropriate high-speed choppers and liquid addition equipment. Actual granulation capability depends on the formulation, mixing configuration, liquid distribution and available process controls.
- Can the Littleford KM-3000-D blend powders with different particle sizes?
The mixer may be used for blending compatible powders and granules with different particle sizes. Mixing performance depends on bulk density, particle size distribution, flow properties and formulation characteristics. Product testing is recommended for applications requiring specific blend uniformity.
- What access openings are included on the mixer?
The machine includes top openings measuring 1-1/2", 3", 10" and 16", along with two side access doors measuring 24" x 16". These openings provide potential access for product charging, inspection, maintenance or connection of compatible process equipment, depending on their configuration.
- How is material discharged from the mixer?
The unit includes a 16" side-bottom outlet for product discharge. The specific discharge valve or closure arrangement should be verified for the machine.
- Can this mixer process abrasive mineral powders?
The machine may be suitable for certain compatible mineral powders. Highly abrasive materials can increase wear on paddles, chamber surfaces and other components. Buyers should evaluate material abrasiveness and inspect equipment condition before use.
- What electrical service is required for the Littleford KM-3000-D?
The main drive motor requires 460-volt, 3-phase, 60 Hz electrical service. The motor is rated at 100 HP and 1,780 RPM. Additional electrical requirements would apply if high-speed choppers or auxiliary equipment are installed.
- What are the mixing chamber dimensions?
The chamber measures approximately 44" in diameter x 116" long. These dimensions describe the mixing chamber rather than the complete overall equipment footprint.
