A ribbon blender is an efficient mixing equipment specially designed for medium to high viscosity materials and various powders. Its core working component is the unique ribbon-shaped (stirring blade), which achieves rapid and uniform mixing of materials through precise mechanical movement. The equipment operates in a laminar flow state, making it particularly suitable for handling high-viscosity liquids, pseudoplastic fluids, as well as powders, pastes, or viscous materials.

 

In terms of structural design, the ribbon blender adopts a U-shaped container as the main body, with double-layer or triple-layer helical stirring blades inside and a reliable driving device. During operation, the inner and outer ribbons rotate in opposite directions, creating a strong material convection: the outer ribbon pushes the material from both ends of the container to the center, while the inner ribbon pushes the material from the center to both ends. This bidirectional movement ensures that the material is fully mixed both axially and radially, which not only improves mixing efficiency but also significantly enhances mixing uniformity.

 

Ribbon blenders have multiple performance advantages:

- High mixing efficiency and good uniformity;

- Large loading coefficient, up to 0.7 to 0.9;

- Low energy consumption and economical operating cost;

- Low material breakage rate, suitable for fragile materials;

- Easy to clean and maintain, supporting quick change of material varieties.

 

In terms of technical parameters, the equipment can handle materials with viscosity up to 100,000 centipoise or more, with a common speed range of 0.5 to 50 revolutions per minute, and the blade tip linear speed is usually controlled within 2 meters per second. The power configuration is flexible and can be adjusted according to the agitator diameter, speed, and material characteristics. The large-diameter and low-speed configuration focuses on macro mixing, while the small-diameter and high-speed configuration is more suitable for micro mixing. For extremely high viscosity materials or working conditions prone to dead zones, a combined design of ribbon and anchor (ribbon-anchor type) can be adopted to further improve the mixing effect and operational reliability.

 

There are various discharge methods, which can be selected according to material characteristics: powder materials often use a pneumatic large door structure to achieve rapid and residue-free discharge; high-fineness or semi-fluid materials can use manual or pneumatic butterfly valves. In addition, the equipment can also be customized with heating or cooling jackets according to process requirements. Heating methods include electric heating and heat-conducting oil heating, while cooling can be achieved by directly injecting cooling water into the jacket. The jacket has a large heat exchange area and high temperature control efficiency.

 

In terms of driving methods, small-sized blenders mostly use a reducer direct connection, which has a simple structure and convenient maintenance; large-sized ones usually use a pulley to drive a cycloid reducer, and its elastic connection has an overload protection function, which can effectively extend the service life of transmission components.

 

Ribbon blenders are widely used in many industries, including chemical, food, pharmaceutical, ceramic, building materials, pesticide, veterinary medicine, feed, plastic and rubber additives, etc. It is particularly suitable for the mixing process of materials such as dry mortar, putty powder, chemicals, metal powder, and cosmetic powder, and can perform excellently in the processing of materials such as condiments, vitamins, fuels, and ores.

 

When selecting equipment, factors such as material characteristics (e.g., viscosity, particle size, fluidity), mixing requirements (uniformity, processing time), and production capacity needs should be comprehensively considered to ensure the best process effect and operational economy.
