Efficiency in bulk solids mixing: Ribbon versus tumble ...

The current manufacturing landscape is rife with supply chain issues that generally fall out of a manufacturer&#;s control. To ease the strain on production lines, it is key to have processing equipment that is efficient and able to support growing demand. Choosing the right equipment can be daunting, but due diligence up front can pay great dividends in the long run. For bulk solids mixing processes, several factors must be taken into consideration, such as plant size, budget and batch size, as well as the bulk density and friability of the materials being mixed.

Bulk solid mixers perform a variety of functions, including blending ingredients, heating or cooling, vacuum drying, and coating solid particles with small amounts of liquid. The goal when selecting equipment is to ensure that the equipment will be able to achieve the objectives of the process accurately and efficiently. 

Among solid-solid blending systems, two of the most common types are the horizontal ribbon blender and the tumble blender. While both blenders offer superior mixing capabilities and can be customized with advanced recipe control systems, there are some significant differences between them and how each design can best be utilized. 

Ribbon blenders

A ribbon blender consists of a U-shaped horizontal trough and an agitator made up of inner and outer helical ribbons that move material in opposite directions. The agitator is powered by a gearmotor drive, which rotates the ribbons at peripheral speeds up to approximately 300 feet per minute and moves material both radially and laterally.

What is a stainless steel ribbon mixer?

Stainless Steel Ribbon Mixer is a kind of mixing equipment used in industrial production. It is mainly composed of a horizontal ribbon mixer and a container made of stainless steel. Through the rotation and shearing force of the ribbon mixer, it can mix different types of materials together quickly and evenly. Stainless steel ribbon mixers are widely used in chemical, pharmaceutical, food and other industries to mix powder, granular or liquid materials to improve product quality and production efficiency.

The stainless steel ribbon mixer is simple and intuitive to use. The operator only needs to put the materials to be mixed into the container and then start the ribbon mixer. The rotating motion of the ribbon mixer pushes the materials to both sides of the container, creating a shearing and folding effect, thereby achieving uniform mixing of the materials. The choice of stainless steel material makes the mixer have good corrosion resistance and hygiene, and meets the requirements of industrial production.

What are the uses of stainless steel ribbon mixer?

Stainless steel ribbon mixers have a wide range of applications. Here are some common uses:

Chemical industry: TIn chemical production, stainless steel ribbon mixers are used to mix and evenly disperse various powders, granules or liquid materials, such as dyes, pigments, plastic particles, rubber, resin, etc.

Pharmaceutical industry: In the pharmaceutical process, stainless steel ribbon mixers are used to mix pharmaceutical raw materials, excipients and preparations to ensure the uniformity and consistency of the drugs, such as preparing tablets, capsules and powders.

Food industry:Stainless steel ribbon mixers are widely used in food processing for mixing flour, seasonings, additives, paste materials, sauces, etc. to ensure the uniformity and taste of food products.

Cosmetics industry: In the cosmetics manufacturing process, stainless steel ribbon mixers are used to mix various cosmetic raw materials, such as lotions, creams, shampoos, perfumes, etc., to ensure product quality and stability.

Laboratory research: Stainless steel ribbon mixers are also commonly used in research work in laboratories to mix reagents, samples and experimental materials for reactions, analysis or testing.

What is the principle of stainless steel ribbon mixer?

The working principle of stainless steel ribbon mixer is as follows:

Structural description:The stainless steel ribbon mixer consists of a horizontal container with a spiral agitator. Spiral agitators usually consist of two or more spiral blades fixed on a central axis.

Stirring motion:: When the stainless steel ribbon mixer starts, the motor drives the central shaft to rotate, causing the spiral agitator to start rotating. The rotating motion of the spiral agitator pushes the material to the sides of the container, creating a shearing and folding effect.

Mixing process: The materials are sheared and folded by the spiral mixer in the stainless steel ribbon mixer, and are constantly cross-mixed. This mixing motion can quickly and evenly mix different types of materials together to achieve even distribution of the mixed materials.

Time control: The mixing time can be adjusted as needed to ensure that the material reaches the required mixing level. Normally, a shorter mixing time will result in a uniform mixing effect.
