What is the difference between a paddle and ribbon mixer?

Paddle Mixer and Ribbon mixer are common mixing equipment used to mix different materials. There are some differences between them in terms of structure, working principle and mixing effects. Here are the main differences between them:

Structural design:

Paddle mixer: A paddle mixer usually consists of one or more horizontally rotating paddles. The paddle is usually fixed on a horizontal axis and is located in the mixing chamber. The shape and layout of the paddles can be designed according to the mixing requirements.

Ribbon mixer: The ribbon mixer consists of two or more ribbons, which are located in the mixing chamber and rotate along the axis of the mixing chamber. Ribbons are usually in the shape of a spiral and transport materials from one end to the other.

Mixing principle:

Paddle mixer: While the paddle rotates, it pushes the material along the axis of the mixing chamber to achieve flipping and cross-mixing of the material. The rotation speed and layout of the paddles can affect the mixing effect.

Ribbon mixer: The rotation of the ribbon transports the material from one end to the other and at the same time pushes the material along the circumference of the mixing chamber. The shape and rotation speed of the ribbon can affect the mixing effect of the material.

Mixing effects:

Paddle mixer: The flipping and cross-mixing of the paddles enable the materials to fully contact and mix, achieving better uniformity. It is suitable for mixing powdery or granular materials, especially for materials that are easy to agglomerate or adhere.

Ribbon mixer: The conveying and pushing effect of the ribbon causes the material to form a circulation in the mixing chamber to achieve better uniformity. It is suitable for mixing powdery, granular and viscous materials, especially for materials that are easy to accumulate or adhere.

Scope of application:

Paddle mixer: Paddle mixer is suitable for mixing powdery, granular and materials that are easy to agglomerate or adhere. It is widely used in food, chemical, pharmaceutical and other industries.

Ribbon mixer: Ribbon mixer is suitable for mixing powdery, granular and materials that are easy to accumulate or adhere. It is widely used in chemical industry, metallurgy, building materials and other industries.

To sum up, there are some differences between paddle mixers and ribbon mixers in terms of structural design, mixing principle and mixing effect. The selection of suitable mixing equipment should be determined based on the nature of the material, mixing requirements and application areas.
