Ribbon Blender Overview

The Ribbon Blender also doubles as a mixer. It is used to mix dry solid and semi-solid raw materials such as powders, pastes, and dried granules. It is an efficient and versatile light-duty machinery used in various sectors, including the Pharmaceutical, Chemical, Cosmetics, Food, and Agricultural industries.

The Ribbon Blender mixer is a type of connective mixer. It has a thin mixing blade that ensures that the raw materials are mixed through controlled motions. The mixing blades are fully sealed at each end to avoid leakage, making them appropriate for dry powders and semi-liquid materials.

The ribbon mixer works with a triple-action technique. The double helix structure of the agitator of the ribbon mixer, which includes the inner and the outer ribbon, works in a reverse direction.

The counter-motion plays an essential role in the successful working of the machine.

The outer ribbon is coiled to transport the raw materials from both ends of the mixing vessel to the middle, while the inner ribbon takes the materials from the centre of the mixing vessel to the opposite ends. The opposing angles and directions of the double helix make the materials flow in a different direction, causing continuous convection circulation and shear blending.

The ribbons rotate at a nominal speed causing a radial motion- the fusion of the counter current and radial motion results in the speedy production of a smooth homogeneous mixture. The estimated mixing time is about 15 to 20 minutes.

However, it is subject to some factors, such as the size and substance density of the raw materials, which also affect the quality of the blended mixture.

The filling factor is the ratio of the volume of materials loaded into the mixer in each batch to the total volume of the mixer vessel when the mixer is in operation.

To derive the best mixing tie, uniformity, and effect, the loading coefficient of the ribbon mixer should be approximately 60 to 65 percent.

If the mixing vessel is overloaded, it could result in mechanical damage to the mixer; also, if the material is not filled to the optimum, it could cause uneven mixing with a long mixing time.

The discharge process is activated after the completion of the blending process. The blended mixtures are ejected through the discharge valve at the bottom of the trough. It could be discharged manually, electrically, or pneumatically.

It is advised to avoid watery, diluted, semi-liquid materials when using the ribbon mixer blender. It reduces the lifespan of the machine.

Metal Plants supplies Ribbon Mixer Blenders comprising high-performance trough format mixing machines. They are used for mixing powders or pastes into a homogenous end product. The sizes of the Ribbon MixerSeries range from about 100 Liters and Above.
