RIBBON/​PADDLE/​PLOW BLENDERS

Blend dry solids, pastes and slurries in 5 to 10 minutes. Versatile, economical and effective when low-energy agitation is required

MUNSON 25 cu ft (0.7 m³) Stainless Steel Ribbon Blender

MUNSON Ribbon, Paddle and Plow Blenders feature stationary U-shaped vessels with flat cover sections on top and a discharge valve on the bottom, and a single, horizontally-oriented shaft rotating on external bearings, with radial arms supporting ribbon, paddle or plow agitator elements, each of which offers distinct benefits across a diverse range of applications.

These blenders force agitators through stationary material, which accelerates the dispersion of individual particles into liquids. As a result, they can blend solids with solids, as well as solids with low or high percentages of liquids to produce smooth pastes or slurries.

From sanitary blenders for pharmaceutical and food products on a laboratory, pilot plant or production scale, to robust, super-duty machines for soil reclamation, building materials and oil sludge treatment, MUNSON custom-engineers each Ribbon, Paddle and Plow Blender to deliver maximum performance for your specific application.

Design and Construction

Mixing capacity is approximately 70 to 80% of total vessel volume, providing: 1) ample space for material flow on the upswing side of the agitator, 2) complete agitator contact with batch materials and 3) proper distancing of an optional spray manifold for introducing liquid additions on the downswing side of the agitator, resulting in uniform solids/liquids distribution.

MUNSON Horizontal Agitated Blenders are offered with ribbon, paddle and plow agitators in many specialized designs to suit each application with top efficiency.

In addition to full-scale machines, MUNSON offers small-scale equipment such as this 1 cu ft (.03 m³) ribbon blender, for laboratory testing, pilot plants and small production runs.

One-piece welded construction, together with heavy-gauge walls and fully reinforced end panels, make these vessels extremely rigid, allowing for exceptionally tight agitator-to-vessel wall tolerances. This, in turn, minimizes residual product in the trough following discharge, reducing material waste and cleaning time.

MUNSON blenders are available constructed of a variety of materials, including but not limited to carbon steel, #304/304L and #316/316L stainless steel, abrasion-resistant steel (AR-200/235), duplex stainless, Hastelloy, titanium and other exotics.

Interior finishes range from a standard clean mill finish to ultra-high sanitary finishes, including 2B, #4, and #7 mirror pharmaceutical finishes to sanitary USDA Dairy finishes with electroplating and chemical passivation. Interior weld polishes range from standard 80 grit clean welds to 240 grit radiused and polished welds.

ROTARY BATCH
MINI MIXERS

Gently blend dry materials in 2 to 3 minutes, add liquids uniformly, discharge with no segregation and sanitize quickly — on a laboratory, pilot plant or small-production scale

This 5 cu ft (142 liter), sanitary Rotary Batch Mini Mixer model MX-5-SS is equipped
with a large access door as standard. Options shown include Swing-Away Intake Chute, Discharge Chute with frame extension, and all stainless steel construction
including support frame and casters.

MUNSON^® Rotary Batch Mini Mixers deliver the same unique advantages as larger in-line models, but in capacities from 0.25 to 15 cu ft (7 to 425 liters) for off-line laboratory, pilot plant, small-production or pre-blending applications.

The four-way mixing action gently tumbles, turns, cuts and folds the material, producing a thorough blend in only 2 to 3 minutes, while preventing degradation by imparting minimal energy and intensity to the product.

This blending action also prevents segregation during discharge regardless of particle sizes, shapes or bulk densities, and provides an ideal fluid bed for liquid additions.

Unlike stationary mixers with agitators, Rotary Batch Mini Mixers produce homogeneous blends with no shear, discharge completely with no stratification, and have no internal shafts or shaft seals to contact material.

Internal mixing flights direct material towards and through a discharge gate for complete evacuation which, together with unrestricted interior access, allows thorough cleaning and sanitizing in minutes.

Mixing efficiency at 100% of rated capacity to as low as 5% (33% with liquid additions) remains constant, providing unsurpassed flexibility. In addition, results obtained are scalable to Munson's high capacity in-line Rotary Batch mixers.

This superior combination of attributes makes the Rotary Batch Mini Mixer ideal for a broad range of laboratory, pilot plant and small-production applications, from pharmaceutical, nutraceutical and food applications requiring absolute cleanliness, to minerals, glass and concrete blending requiring extraordinary durability.

MUNSON also offers in-line Rotary Batch mixers that have stationary inlets and outlets and capacities from 5 to 600 cu ft (142 liters to 17 m³), and Rotary Continuous Mixers with capacities from 25 to 5000 cu ft/h (708 liters to 142 m³/h).

With a 0.25 cu ft (7 liter) batch capacity, model MX-1/4 is Munson's smallest Rotary Batch Mini Mixer. It is equipped as standard with manual tilt and removable drum, with results scalable to models having capacities to 600 cu ft (17 m³), making it ideal for countertop testing.

FLUIDIZED BED MIXERS

Mix low- to medium-density bulk materials, including liquid additions, in 30 seconds (typical) minimizing degradation of friable materials.

MUNSON Fluidized Bed Mixers are offered in capacities from 0.21 to 280 cu ft
(5.90 liters to 8.01 m³). Model MF-5-SS 4.24 cu ft (0.120 m³) shown.

MUNSON^® Fluidized Bed Mixers are recommended when mixing low- to medium-density materials (≤50 lbs/cu ft or ≤800 kg/m³) ranging from powders to pellets — particularly friable materials — with or without liquid additions, in applications requiring short cycle times, relatively gentle product handling and infrequent wash downs.

The MUNSON Fluidized Bed Mixer is among the fastest of all mixers, with cycle times of 10 seconds to two minutes, with 30 seconds typical, yielding a ~5% CV (coefficient of variation).

Flat, angular paddles with overlapping paths effectively sweep material from two parallel U-shaped troughs toward the center and upward, causing it to become airborne in a "fluidized zone" above the longitudinal centerline of the mixing chamber, where discreet particles of batch ingredients readily intersperse, regardless of disparities in particle size, shape or bulk density.

The fluidized zone is also an ideal location in which to spray high- or low-viscosity liquids, which disperse more readily and can be added in relatively high volumes while maintaining free-flowing characteristics of the batch.

This fluidized mixing action also creates less shear than other agitated blenders which, together with extremely short mixing times, results in less product degradation.

The fluidized bed mixer also discharges more rapidly, through its full-length, drop-bottom gates, allowing material to empty from the machine rapidly.

And whereas ribbon, paddle and plow blenders leave a pronounced "heel" of material in the trough following discharge, the fluidized bed mixer evacuates a much greater percentage of material, reducing the need to manually remove — and waste — material between product changeovers.

The MUNSON Fluidized Bed Mixer is configured with two counter-rotating shafts turning paddle agitators rapidly within two, parallel U-shaped troughs.

CYLINDRICAL
PLOW BLENDERS

For batch blending of extremely fibrous, interlocking, dense, abrasive or moist/oily materials at higher speeds, with higher intensity, and with more uniform results than possible with trough style Ribbon, Paddle or Plow Blenders.

Cylindrical Plow Blender

Unlike trough-style Ribbon, Paddle and Plow Blenders, MUNSON^® Cylindrical Plow Blenders consist of a cylindrical vessel and a mixing shaft that rotates about 4-times faster. The vessel is typically filled to 60 percent of capacity that, together with fast rotation of the mixing shaft, serves to fluidize the material and fill the entire mixing vessel with airborne material, maximizing material transfer rates while minimizing impact and degradation.

As a result, MUNSON Cylindrical Plow Blenders can achieve 100 percent uniform blends of materials in ratios down to one part per thousand, blend significantly faster than trough style horizontal mixers, and handle a greater variety of materials, including extremely fibrous, interlocking, dense, moist, sticky, abrasive, fragile or otherwise poor-flowing materials. Cylindrical Plow Blenders are not, however, recommended for mixing of pastes.

VEE CONE BLENDERS

Mix dry and granular bulk materials, including liquid additions, in 15 to 30 minutes. Gentler and easier to sanitize than agitated machines.

MUNSON Vee Cone Blenders for laboratory and other small batch applications feature a cantilevered mounting system that supports interchangeable vessels in six sizes: 0.25, 1, 2, 4, 8 and 16 quart (0.24, 0.95, 1.89, 3.79, 7.57 and 15.14 liter).

A MUNSON^® Vee Cone Blender (also known as a "V Cone Blender" and "V Blender") is comprised of two inclined cylinders that rotate, causing bulk material to fall and converge during half of the rotation, and divide during the other half. This mixing action requires significantly less horsepower/kilowatts than ribbon blenders and other agitated machines.

Smooth internal surfaces, with no internal baffles, shafts or bearings, allow unobstructed material flow, as well as complete discharge through a gate valve. The absence of residual material, together with easy access to internal surfaces through the discharge valve and doors at the ends of the inclined cylinders, allows thorough sanitizing in minutes, preventing cross-contamination between changeovers.

Uniform blends are typically achieved in 15 to 30 minutes with equal efficiency at fill volumes from 100% to 50% of rated capacity, depending on material.

Suitable for dry and granular materials, MUNSON Vee Cone Blenders provide a tumbling action that is gentler than agitated machines in which blades, paddles or plows are forced through stationary material.

VARIABLE-INTENSITY BLENDERS

Greater versatility than continuous ribbon/​paddle/​plow blenders or pug mills: Slow, gentle blending, homogenizing, coating and de-dusting, up to high-intensity, high-shear mixing and lump-breaking of dry materials, dense pastes and slurries — at high rates.

Engineered, constructed and finished to sanitary standards, this MUNSON^® model VIM-124-S316
Variable-Intensity Continuous Blender allows rapid, thorough cleaning and sanitizing.

Infinitely adjustable rotor speed, together with variable-pitch paddles, allows fine-tuning of blending action, from slow-speed consistent progression of material through the cylindrical chamber, to high-speed "backwashing" of material through turbulent zones for rapid, high-shear interspersing of particles — with typical residence times of 20 to 30 seconds.

Munson's Variable-Intensity Continuous Blender is based on a horizontal, cylindrical vessel with a single agitator rotating at low to high speed, delivering a wide range of mixing/blending capabilities in high capacities.

Small to large volumes of liquids can be injected through ports strategically located on the vessel, and can be driven into the material rapidly and uniformly.

The agitator is comprised of a large-diameter, solid main shaft equipped with paddles affixed to the main shaft in either of two ways: with threaded paddle shafts that are individually adjustable for pitch up to 180° to impart various degrees of blending intensity, or with permanently fixed and fully seal-welded paddle shafts for sanitary applications.

Shorter residence times of 20 to 30 seconds are typical for dry blends of major ingredients, while longer residence times may be required for critical blends containing minor additives and for materials requiring increased retention for liquid absorption or other conditioning.

An optional weir immediately upstream of the discharge can increase the residence volume as needed for blending of certain dry materials having fluid flow characteristics.
