Used Ribbon Blenders for Sale
Ribbon blenders are horizontal mixing machines designed to blend powders, granules, flakes, and other dry bulk solids using inner and outer helical ribbons mounted on a central shaft. This ribbon agitation pattern moves material in opposing directions to create a consistent, efficient blend across the trough. Used ribbon blenders are widely used in food processing, chemicals, pharmaceuticals, nutraceuticals, plastics, and other industrial applications where uniform dry mixing is required. Aaron Equipment offers used ribbon blenders for sale in a range of sizes, materials of construction, and discharge configurations to support varied processing requirements.

54547001Used Rietz RS-28-K5408 Dual Shaft Double Ribbon Blender – 60 Cu. Ft. Working Capacity – 304 Stainless Steel
Used- Rietz Manufacturing Co. Dual Shaft Double Ribbon Blender, Model RS-28-K5408. Approximate 60 cu. ft. working capacity, 75 cu. ft. total capacity, and can process approximately 4,000 to 5,000 pounds per batch, depending on product bulk density. Engineered for high-capacity, heavy-duty batch mixing in demanding industrial processing environments. Constructed with 304 stainless steel product contact surfaces, this blender is designed to provide rapid, efficient, and highly uniform mixing of dry powders, granules, bulk solids, and products requiring liquid addition. (2) 28" counter-rotating dual ribbon agitators that utilize a counter-flow ribbon design to move material both axially and radially, producing fast, thorough, and homogeneous blending while minimizing product degradation. The heavy-duty dual shaft design, utilizing chain or gear-driven independently driven ribbon assemblies, provides reliable performance and excellent product turnover for consistent batch-to-batch results. Designed to handle both dry materials and products requiring liquid addition, the mixer is equally well suited for blending powders, granules, slurries, and other process materials. Product discharge is accomplished through dual air-operated (pneumatic) bottom end discharge doors, allowing rapid, controlled, and virtually complete batch evacuation while minimizing residual product. The unit is mounted on a heavy-duty four-leg stainless steel frame and is equipped with safety grates, protective guarding, and hinged covers to enhance operator safety and simplify loading and inspection. Its sanitary stainless steel construction makes it well suited for food, pharmaceutical, nutraceutical, chemical, agricultural, mineral, plastics, and other industrial processing applications requiring durability, corrosion resistance, and ease of cleaning. The mixing chamber measures approximately 72" long 56" wide 36" deep and operates at an output speed of approximately 30-35 RPM.

Ribbon Blender Applications & Typical Use Cases
Used ribbon blenders are commonly selected for batch mixing applications involving free-flowing powders and bulk solids. Typical uses include dry ingredient blending, spice and seasoning preparation, powdered chemical mixing, resin and additive blending, fertilizer mixing, and nutraceutical formulation. In some configurations, ribbon blenders are also used for light slurry or paste mixing, depending on material characteristics, agitation design, and cleanability requirements.
When to Choose a Ribbon Blender
Ribbon blenders are often the right choice when a process requires efficient batch blending of dry materials with a relatively uniform particle size distribution. They are commonly preferred over more aggressive mixers when gentle, consistent mixing is needed without excessive shear. Operations that handle powders, granules, or light solids in repeatable batch sizes frequently use ribbon blenders because they offer straightforward operation, flexible capacity options, and reliable mixing performance for general-purpose industrial blending.
Used Ribbon Blender Buying Considerations
When evaluating a used ribbon blender, consider:
Working capacity: Match batch size requirements to usable trough volume, not just total vessel size.
Material of construction: Confirm carbon steel or stainless steel suitability based on sanitation, corrosion resistance, and product compatibility.
Ribbon and shaft condition: Inspect for wear, buildup, repairs, or uneven ribbon clearance that could affect blend quality.
Discharge design: Review valve type, outlet size, and discharge efficiency for your downstream process.
Drive and controls: Evaluate motor size, gearbox condition, and control configuration for your mixing cycle and plant integration requirements.
Why Buy Used Ribbon Blenders
Buying a used ribbon blender can reduce upfront capital costs while giving processors access to proven mixing equipment that is available much faster than new machinery. Used units may also provide a practical solution for plant expansions, replacement projects, pilot production, or secondary process lines. For many operations, purchasing a used ribbon blender helps balance performance, availability, and budget.

A ribbon blender is a horizontal batch mixer that uses double helical ribbons to move material in opposing directions and create a uniform blend. It is commonly used for mixing powders, granules, and other dry bulk solids in industrial processing environments where consistency and repeatability are important.
Ribbon blenders are used for blending dry ingredients, powders, granules, flakes, and similar bulk materials. Common applications include food ingredient mixing, chemical powder blending, nutraceutical formulation, fertilizer preparation, and plastics compounding where even material distribution is required.
Ribbon blenders are typically used for gentle, efficient batch blending of dry solids, while other mixers may be better suited for high-shear mixing, liquid incorporation, or more intensive material working. Ribbon blenders are often chosen when uniform mixing is needed without excessive particle degradation or overly aggressive agitation.
The cost of a used ribbon blender depends on factors such as manufacturer, capacity, material of construction, sanitary design, agitation configuration, and overall condition. Larger stainless steel units or specialized sanitary models typically command higher prices than smaller general-purpose machines.
