Product Introduction

The airflow classifier, cyclone separator, dust collector, and induced draft fan form a classification system. Under the suction force of the fan, the material moves at high speed from the lower inlet of the classifier to the classification area with the rising airflow. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated. Fine particles that meet the particle size requirements enter the rotary fan separator or dust collector through the gap between the classification wheel blades for collection. Some of the coarse particles are carried by the fine particles and collide with the wall, and their velocity disappears. They descend along the cylinder wall to the secondary air outlet. Through the strong washing effect of the secondary air, the coarse and fine particles are separated, and the fine particles rise to the secondary classification area. The coarse particles are discharged at the discharge port.

Product features

● Suitable for fine classification of dry process micron level products, it can classify spherical, sheet-like, and needle shaped particles, as well as classify particles of different densities.

● The particle size of graded products can reach D97:8-150 microns, and the product particle size is infinitely adjustable, making it very convenient to change varieties.

● The classification efficiency (extraction rate) is 60% to 90%. Materials with good fluidity have higher classification efficiency, while those with poor fluidity have lower efficiency.

● Adopting a vertical graded turbine device, with low rotational speed, wear resistance, and low system power configuration.

● It can be used in series with multi-level classifiers to produce products with multiple particle sizes simultaneously.

● It can be used in series with ball mills, vibration mills, Raymond mills and other grinding equipment to form a closed loop.

● The control system adopts program control, with real-time display of operating status and easy operation.

● The system operates under negative pressure, and the dust emission does not exceed 40mg/m3. The equipment noise is reduced by noise reduction measures, and does not exceed 75dB (A).
