Stainless Steel 316 Ribbon Blender is a specialized mixing machine designed for homogeneous blending of dry powders, granules, or low-viscosity materials, constructed from SS316. Widely used in the pharmaceutical, food, chemical, and nutraceutical industries, it ensures compliance with GMP standards due to its non-reactive, durable, and easy-to-clean properties. The “ribbon” design refers to the helical agitators that move materials in a counter-current motion for thorough mixing. Industrial Ribbon Blender Mixer is an efficient and versatile blending machine for mixing of dry granules & powders homogeneously. Approximately two third of the volume of the container of Ribbon Blender is filled to ensure proper mixing. The Ribbon Blender gives best result for mixing of dry powder & granules due to the design and shape of the mixing ribbon and product container. The outer ribbon displaces the material from the ends to the centre while the inner ribbon moves the material from the center to the ends. This counter-current action results in homogenous blending. The ribbons rotate at approximately 70 – 100 meters per minute and move the material both radially and laterally to ensure thorough blends in short cycle times.

Material is charged in the blender through nozzles or feed-hoppers mounted on the top cover of the blender. Suppose if screw feeder is opted with mixer, then material to be load onto screw feeder and it will feed powder into blender. Filling to be done about 70 percent of the total volume of the container. This is generally up to the level of the outer ribbon’s tip. After feeding completes then please close the top cover of the blender and tighten the latches. Now start the machine form the control panel.
During the blending operation, the outer ribbons of the agitator interchange the material from the ends to the center while the inner ribbons transfer the material from the center to ends. Radial movement is achieved because of the rotational motion of the ribbons. The difference in the peripheral speeds of the outer and inner ribbons results in axial movement of the material along the horizontal axis of the blender. As a result of the radial and the counter-current axial movement, homogenous blending is achieved in short time. Blending is generally performed in 15 to 20 minutes cycle time. Mixing efficiency of ribbon blender depends upon particle size and its bulk density. Generally, ribbon mixer blender with 95% efficiency in most of the cases. Ingredients with similar particle size and bulk densities tend to mix faster as compared to ingredients with variation in these attributes.
After mixing, material is discharged from a discharge valve located at center bottom of container. The discharge can be fitted with any of these valves like slide-gate, butterfly, flush bottom, spherical and other types depending on the application. The operation of the valves can be manual or pneumatically actuated as per requirements. Sifter can be installed at discharge of the blender for sieving the output materials. Ribbon blenders can be designed for multiple discharge ports. Unlike tumbling blenders where 100% discharge of material is achieved by gravity, in a ribbon blender the material is discharged by rotation of the ribbon agitator. Finished powder can be collected directly on mobile container or can discharge onto conveyor for further operations.

Material is loaded into the U-shaped trough (typically 60–70% of gross volume). The inner and outer helical ribbons rotate at 70–100 m/min, creating counter-current flow: the outer ribbon moves material from ends to center, while the inner ribbon moves it from center to ends. This combination of radial and axial movement achieves uniform blending (up to 95% efficiency) within 15–20 minutes.
We offer a wide range from lab to large production scale:
Custom sizes and higher capacities are also available.
Very easy. The machine features mirror-polished SS 316 surfaces, a smooth U-shaped trough, and easily accessible ribbons. The centrally located flush bottom discharge valve and removable shaft seals allow quick cleaning and fast product changeovers. It supports manual cleaning as well as optional CIP systems, meeting strict GMP and food-grade sanitation requirements.
