The double helix belt mixer is a commonly used mixing equipment. Its mixing principle is based on the rotation and movement of the double helix belt.

The device consists of two intertwined spiral bands that rotate along the axis of the device and move in the direction of the axis. This design enables the material to achieve good mixing and shearing effects during the mixing process.

When the equipment starts to rotate, the spiral belt pushes the material from one end of the equipment to the other. At the same time, the rotation of the spiral belt will also cause shearing and folding of the material. This combination of pushing and shearing enables the material to be fully mixed inside the equipment.

The double helix belt mixer also has some other features, such as adjustable mixing speed, controllable mixing time, and is suitable for a variety of materials. It is widely used in chemical, food, pharmaceutical and other industries to mix powdery, granular and viscous materials to achieve uniform mixing.

The double-spiral belt mixer uses the rotation and movement of the spiral belt to mix the materials by pushing and shearing to achieve a uniform mixing effect.
