The Design of Ribbon Blender:

The horizontal ribbon mixer is made up of three main components: a transmission unit, a U-shaped barrel, and a double-layer ribbon mixer. The blender’s shell has a U-shaped design, and at its center, there’s a rotating agitator. This agitator features a double helix design, which enables it to efficiently mix bulk materials in two directions through a convective motion.

Ribbon Blender-design

Structure and features:

The U-shaped containers incorporate robust mixing blades and transmission components, featuring a unique U-shaped cylinder structure known as the “ChangTi cylinder.” This design ensures minimal resistance during the movement of mixed materials, which can be in the form of powders or semiliquids, within the cylinder.

To create an efficient mixing environment with low power consumption, both positive and negative rotation ribbons are installed on the same horizontal axis. These ribbons create a dynamic mixing process. Additionally, spiral strip blades, consisting of either a double or triple layer, are placed on the outer spiral surfaces of the cylinder. These spirals facilitate the movement of materials from two sides towards the central pool.

Simultaneously, inner spiral materials are transported from the central pool towards both sides of the cylinder. This dual-directional movement induces a vortex effect within the materials at lower power levels. Consequently, this setup accelerates the mixing speed and significantly enhances the uniformity of the mixing process.

Discharging mode:

The spacious design of this system offers some valuable advantages when working with pneumatic materials. One key benefit is the ability to discharge completely without leaving any residues behind. To handle either finely ground materials or semiliquids, you can choose between manual butterfly valves or pneumatic butterfly valves.

Furthermore, this system can be equipped with a heating or cooling jacket for precise temperature control. The heating options include electric heating and heat conduction oil heating, offering flexibility based on your specific needs. Cooling is achieved either through a direct water jacket or a large heat exchange area, ensuring rapid cooling.

In smaller mixers, a simple reducer direct-drive mechanism is used, characterized by its straightforward structure and high operational reliability. Maintenance is also convenient in these cases. In contrast, larger mixers employ a pulley-driven system with a cycloid speed reducer. This setup features an elastic connection that offers the advantage of overload protection during operation.

What is Ribbon Blender?

A ribbon mixer blender is a type of blender designed for lighter mixing tasks, primarily used with pre-processed powder components such as dried granules and pre-sieved powders. This blender operates with low shear, making it ideal for solid-solid mixing. It can also handle solid-liquid mixing when a high shearing force isn’t needed.

One of its advantages is that it takes up less vertical space compared to larger volume mixers, making it a space-efficient choice.

The principle of Ribbon Blender:

Ribbon blenders work based on a combination of convection and diffusion mechanisms.

Convection mixing involves the larger-scale movement of solid materials. This happens when the solids are rotated along the horizontal axis of the agitator assembly.

On the other hand, diffusion mixing focuses on the micro-level blending, where individual particles move relative to the particles around them. In a ribbon blender, diffusion occurs as particles in front of the ribbon move in one direction while nearby particles either remain still or lag behind.

These dual mechanisms, convection and diffusion, work together to effectively mix and blend solid materials in the blender.

Industrial grinders are essential machines in many industries, as they help reduce the size of materials, improve efficiency, and increase productivity.

Jet mills, pin mills, and ball mills can all be categorized as ultrafine grinders. These mills are capable of producing very fine particles and powders, and are commonly used in industries such as pharmaceuticals, food processing, and cosmetics, where ultrafine particles are required for various applications. The specific type of mill used as an ultrafine grinder will depend on the material being processed and the desired end product.

Ultrafine grinders use mechanical grinding and air pressure to achieve size reduction. In these machines, the material to be ground is fed into a grinding chamber, where it is subjected to mechanical forces such as impact, compression, and attrition. As the material is ground, it is also exposed to a stream of high-pressure air or gas, which helps to break down the particles and create a fine powder.

The combination of mechanical grinding and air pressure allows ultrafine grinders to achieve a very fine particle size, often in the sub-micron or nanometer range. This makes them particularly useful for applications that require very small particle sizes, such as in the pharmaceutical, cosmetics, and food industries.

A turbo grinder is a type of angle grinder that is specifically designed for heavy-duty applications, such as grinding and cutting thick metal and concrete. It features a high-powered motor and a specialized blade or wheel that rotates at high speeds to remove material quickly and efficiently.

Turbo grinders are typically larger and heavier than standard angle grinders, and are often used in industrial settings such as construction sites and metalworking shops. They are capable of removing large amounts of material in a short amount of time, making them ideal for projects that require aggressive grinding or cutting.

Some turbo grinders may also come equipped with dust collection systems, which help to control the amount of debris and dust generated during use. This can be especially important when working with concrete or other materials that create a lot of dust when ground or cut.

Right size is definitely important for grinder business. 
If your business is small, you may not have the space to accommodate a large grinder. Read keep in mind, While, that a smaller grinder doesn’t have to mean that it’s not able output as much as a bigger one.
On the contrary, if you have a lot of space, you may require different things from your grinder.
For example, you may want to have dust collector and material feeder for your enviornment production and operation convenience.

The Ribbon Blender, designed for batch-style operations, has established itself as a reliable powerhouse in handling bulk solids. It’s adept at processing a diverse array of materials, spanning from seasonings and beverage mixes to pharmaceuticals, chemicals, plastics, and agricultural powders or granules. This wide-ranging capability makes it a sought-after and adaptable choice across multiple industries.

This blender boasts several functions, including the ability to heat, cool, or dry materials in a vacuum environment. Additionally, it can efficiently apply a thin coating of liquid onto solid particles. Furthermore, it’s proficient at blending wet applications like soups, batters, slurries, and specific pastes. In essence, the Ribbon Blender offers a comprehensive solution for various mixing and processing needs.

Ribbon Blenders are composed of a U-shaped horizontal trough and a sturdy agitator shaft fitted with spokes that support both outer and inner helical blades known as ribbons. These ribbons play a crucial role in mixing.

Powered by a gearmotor drive, the agitator rotates and generates a peripheral speed of about 300 feet per minute (fpm). Here’s how the ribbons work: the outer ribbons guide the ingredients towards the center of the blender, while the inner ribbons move the materials towards the blender’s wall. This speed difference between the outer and inner ribbons causes the material to move both laterally and axially (along the horizontal axis of the blender) in opposite directions.

These combined radial and two-way axial mixing actions create a dynamic mix of small-scale random motion (diffusion), large-scale random motion (convection), and shear forces. These movements result from the interactions between particles and the agitator, particles and the blender wall, and particles colliding with each other.

When your application demands it, LK Ribbon Blenders can be customized with special materials such as Hastelloy C-276 or abrasion-resistant carbon steel. If you need more power for high-density blending, heavier-duty, higher-horsepower options are available. You can also opt for air-purged mechanical seals, end wall scrapers, high-performance sanitary valves, load cell systems, and other premium upgrades. These blenders can even be designed for vacuum operation up to 29.5 inches of mercury (Hg) and positive internal pressure.

In various industries, from food production to pharmaceuticals, mixing plays a pivotal role in combining ingredients to create the desired end product. Mixers come in a range of shapes and sizes, but the two most commonly employed types are ribbon mixers and paddle mixers. Each has its own set of pros and cons, so it’s crucial to grasp the distinctions between them to make an informed choice about which mixer suits your specific needs.

Ribbon Mixers

Ribbon mixers typically feature a U-shaped trough and employ two or more ribbons arranged either horizontally or vertically. These ribbons rotate in opposing directions, producing a spiral mixing action that blends the ingredients effectively. Ribbon mixers excel in handling large batches of materials due to their ability to accommodate substantial quantities and their open, U-shaped trough that simplifies loading.

One significant advantage of ribbon mixers is their capability to blend materials of varying sizes, shapes, and densities in substantial quantities. This makes them ideal for mixing powders, granules, and liquids. Additionally, ribbon mixers can operate at low speeds, making them suitable for fragile products that require gentle mixing to prevent damage.

However, ribbon mixers have some drawbacks. They tend to develop dead spots in the mixing chamber, which can result in uneven mixing and material separation, particularly when dealing with smaller batches. To ensure thorough mixing, additional scraping or tumbling may be necessary. Moreover, if heating is required, ribbon mixers are not the most efficient choice due to their open-top design, which hinders heat transfer.

Paddle Mixers

Paddle mixers typically have a cylindrical shape and employ two or more paddles that rotate in the same direction, often staggered. These mixers can generate a shearing action when needed or operate gently without shearing, efficiently blending ingredients as required. Paddle mixers are versatile, suitable for both smaller and larger batches, and capable of rapidly mixing materials in a short timeframe.

One of the standout advantages of paddle mixers is their ability to delicately and efficiently blend materials with diverse sizes, shapes, and densities. Additionally, they can operate at high speeds, making them well-suited for tasks that demand swift mixing.

Heat transfer is another area where paddle mixers shine. Their closed tops and cylindrical design offer increased surface area, resulting in enhanced heat transfer efficiency.

However, one limitation of paddle mixers is that they may not be as efficient when loading bulk materials directly into the mixer. The cylinder-type configuration often necessitates conveying during the loading process.

In summary, both ribbon mixers and paddle mixers have their strengths and weaknesses, and the choice between them largely depends on the specific requirements of your mixing tasks.

Ribbon blenders offer a cost-effective solution for mixing tasks, but like any equipment, they come with their own set of advantages and disadvantages, which we’ll delve into below.


Versatile Mixing: Ribbon blenders are widely used in industries for blending both solid and liquid ingredients when needed. They excel at achieving the desired mixing results.

Quick Mixing Cycles: These blenders are capable of running short and speedy mixing cycles, ranging from a few minutes to 15 minutes. Despite the impression of high RPM (revolutions per minute), ribbon agitators typically run at a tip speed of up to 300 feet per minute.

Efficient Discharge: When equipped with a central discharge port, ribbon blenders offer a complete discharge feature. Running the machine at lower speeds allows for easy emptying of the mixing vessel. Moreover, multiple powder valves can be used on the mixer’s discharge port. Many plug valves can be flush with the mixer body’s internal surface when closed, preventing the buildup of the mixture during the mixing process.


Limited Working Volume: Ribbon mixers have a working volume capacity of around 30%. If the capacity falls below this level, it may not facilitate proper contact between the ribbons and materials being mixed. While the mixer can operate at 100% capacity in some applications, the ideal mixing capacity typically falls within the range of 50-70%.
In conclusion, ribbon blenders are a valuable asset in various industries due to their efficient mixing capabilities and cost-effectiveness. However, they do have limitations in terms of working volume, which should be considered when choosing the right mixer for your specific application.

The ribbon blender machine consists of a U-shaped horizontal trough and a custom-made double-helical ribbon agitator that rotates inside the trough.

The Spindle Speed(rpm/min) is from 17~58rpm/min.

The ribbon mixer’s dimensions and layout are meticulously designed and arranged to achieve a perfect homogeneous product by rapidly and effectively mixing and blending the raw materials.

Each part of the machine is constructed with great care, taking into account the materials they come into contact with to minimize product contamination. The primary components of the ribbon mixer are made from stainless steel, which undergoes refinement processes like polishing, mirror polishing, sandblasting, and wire drawing.
