Daswell Powder turbo classifier is designed for precise particle size control in a powder processing plant. It is a key classification machine for improving the finished powder quality and production stability.

It classifies a wide range of materials with high efficiency. For example, for the calcium carbonate powder, quartz powder, talc powder, barite powder, and limestone powder processing plants, the turbo classifying machine plays a key role. It is widely used in powder production lines serving industries such as plastics, rubber, coatings, paints, and fine industrial fillers.

By integrating the turbo classifier into the grinding system, the particle size distribution can be accurately controlled. And the overall production efficiency is significantly improved.

Working Principle

Material Feeding

The powder is sent to the classifier from the lower inlet by the main fan. The upward airflow rapidly transports the powder to the main classification zone, ensuring stable and continuous feeding.

Primary Centrifugal Classification

When the powder enters the areas near the high-speed rotating classification turbine, the strong centrifugal force separates the particles based on size and density. The qualified fine powder passes through the blade gaps of the classifying wheel. Then the dust collector collects them well.

Wall Impact and Particle Deceleration

Some fine particles attached to coarse particles will lose their velocity after hitting the chamber wall. Then they slide downward along the inner cylinder wall to the secondary air inlet, enabling further classification.

Secondary Airflow Separation

The secondary air enters the chamber with a strong washing effect, separating fine particles from coarse particles effectively. The fine powders are carried upward again and return to the secondary classification zone for more precise size control, improving classification accuracy and reducing fine powder loss.

Coarse Particle Discharge

The coarse particles can not rise with the airflow because they are heavier. Thus, they fall toward the discharge port directly. These oversized particles are usually returned to the grinding system for size reduction.

This multi-stage classification mechanism ensures stable particle size control and high classification efficiency.

Benefits of Turbo Classifier

Higher classification effects

The optimized turbine structure and airflow field enable stable and precise particle size control. The system is suitable for fine powder classification where strict fineness requirements are required. Whether you need to use our classification machine for calcium carbonate processing or quartz powder production, it can meet your needs.

High efficiency with low energy consumption

Optimized airflow design reduces unit energy consumption by up to 20% compared to conventional classifiers, directly lowering your operational expenses. And for high-volume powder production needs, it is a cost-effective solution.

Applicable for various powder processing plants

The turbo classifier performs effectively for both light powders (such as calcium carbonate and talc) and heavy powders (such as barite). It is suitable for various powder processing lines.
