How does a vertical screw mixer work?

Vertical screw mixer is a commonly used mixing equipment, mainly used for mixing dry powder and granular materials. It adopts a vertical structure with a cylindrical container and a spiral stirrer at the bottom. The working principle and working process of vertical screw mixer will be introduced in detail below.

working principle:

The working principle of the vertical screw mixer is based on the rotational movement of the spiral mixer. When the mixer is started, the spiral agitator starts to rotate, pushing and pulling the material, causing it to be sheared, turned over and cross-mixed within the container. Through the rotation of the agitator, the materials are continuously circulated to achieve the purpose of mixing.

work process:

(1) Feeding: First, add the dry powder or granular materials to be mixed into the container of the vertical spiral mixer through the feeding port. The feed inlet is usually located at the top of the mixer, and materials can be fed manually or automatically.

(2) Mixing: After the material enters the container, start the mixer. The spiral agitator starts to rotate, pushing the material upward and pulling it downward, causing it to be sheared, turned over and cross-mixed in the container. The rotating motion of the spiral mixer enables the materials to fully contact and mix, achieving a uniform mixing effect.

(3) Discharge: After mixing is completed, open the discharge port and take out the mixed materials from the container. The discharge port is usually located at the bottom of the mixer, and materials can be taken out manually or automatically.

(4) Cleaning and maintenance: After use, the vertical spiral mixer needs to be cleaned and maintained. Since the inner wall of the mixer container is smooth and there are no dead corners, it is relatively easy to clean. At the same time, the mixer and transmission parts need to be inspected and maintained to ensure the normal operation of the mixer.

The working process of the vertical screw mixer is simple and efficient. Through the rotational motion of the spiral mixer, the materials are fully sheared, turned over and cross-mixed, achieving a uniform mixing effect. Vertical screw mixer is suitable for chemical, pharmaceutical, food, pesticide and other industries. It can mix materials of different densities, different particle sizes and different properties. It has the characteristics of compact structure, excellent mixing effect and easy operation, and is widely used in the production process.
