Ribbon Blenders
Ribbon Blenders for Industrial Mixing of Bulk Solids, Powders, and Liquids
CMT offers Ribbon Blenders that are engineered to meet demanding production requirements while delivering exceptional quality, durability, and long-term performance. Designed with precision craftsmanship and attention to detail, every aspect of the mixer’s construction is optimized to improve blending efficiency and maximize production throughput. Ribbon Blenders are highly versatile and capable of handling a wide range of mixing applications. They are particularly effective for low-density, free-flowing materials and are well suited for blends containing small agglomerates, where the ribbon agitator’s increased shearing action promotes superior product consistency.
The ribbon design provides efficient low-speed agitation, helping maintain uniform blends throughout extended production cycles while minimizing product degradation. In addition, the reduced surface area of the ribbon agitators lowers material resistance, allowing for efficient operation with minimal power consumption. Available with either center or end discharge configurations, CMT Process Solutions Ribbon Blenders are built for flexibility and dependable performance. Standard features include close-clearance tolerances, heavy-duty solid shafts, and rugged all-welded construction for long service life in demanding processing environments.

Features and Advantages
Choosing the Right Agitator on Your Ribbon Blender
Double Ribbon
The double ribbon agitator is best for low density, free-flowing materials that are of like size and shape. For that reason, the double ribbon is a great choice for many powders. The double ribbon is advantageous in applications requiring a lot shear (work), such as salt or sugar. The inner and outer ribbons move ingredients from end–to-end in opposite directions. The blending action occurs by rolling material back and forth. Double ribbon agitators are designed with a continuous spiral, with no gaps between the ribbon flighting. The ribbons are welded for the same level of sanitation as paddles, and although it may require more careful inspection, the design eliminates potential for pockets of stagnant material.
Applications: Powders, nutraceuticals, pharmaceuticals, chemicals, pet foods, drinks drink mixes, dairy powders
Hybrid Paddle/Ribbon
A hybrid offers a higher level of agitation than the paddle or ribbon alone. The double-reversing design creates a mixing combination of the figure-8 movement of the paddle style with the scrubbing action of a ribbon blender. The hybrid is best used when products contain a lot of texture or bulk. This translates into increased energy being transferred into the ingredients, and even product levels inside of the trough.
Applications: Cappuccinos, sugar/salt-based spices
Choosing the Right Trough For Your Ribbon Blender
U-Shaped Troughs
The U-Shaped Trough design is used for ambient conditions or low pressure/vacuum mixing applications and utilizes a flat top cover. The cover can be supplied with inlet nozzles as needed and provisions for dry powder addition. This design allows agitator removal from either the top or end.
Marion U-shaped troughs are:
- The largest in production capacity
- The easiest to clean
- The most commonly used
Semi-Cylindrical Troughs
The Semi-Cylindrical Mixer Trough is built for low pressure requirements. This type features heavy reinforcing along the straight sides, a heavy plate cover design, and a drive that has a concentric shaft reducer with final roller chain drive. This type of paddle mixer trough is curved through 300° so the trough is closely swept by the agitator. "Pinch points" are eliminated on the downsweep side where large, fragile materials can be damaged. Less material accumulates on the upsweep side providing for faster, more thorough mixing.
Our semi-cylindrical troughs are effective for:
- Pastes or slurries
- Reducing the degradation of fragile ingredients
- Allowing for the mixing of oversized materials,
- Mixing sticky or tacky material
Full Cylindrical Trough
This type of paddle mixer is completely cylindrical, offering the best horizontal mixer design for internal pressure or vacuum. In addition, closely swept interior surfaces give excellent heat transfer surface to product volume ratios.
Our Full Cylindrical Troughs are effective for:
- Agitator sweeps 360 degrees of rotation
- Largest contact surface area for heating or cooling
- Appropriate for vacuum or low pressure applications
