Vertical Air Classifier

Single Rotor/Multiple Rotor

Vertical staged turbine is used ,speed of wheel is controlled by inverter, particle size can be adjusted freely, Classifying efficiency (extraction ratio) can be 60%~90%. Available D50:2-45μm

Features:Low speed, stand wear and tear, low system power configuration; clean production process; PLC control system, easy operation.


Application:Widely used in chemical industry, minerals (especially suitable for non-mineral materials classifying, such as calcium carbonate, kaolin, quartz, talc, mica), metallurgy, abrasives, ceramics, refractory materials, medicines, pesticides, food, health products, new materials, etc. industry.

Unique advantages

Vertical impeller

Ertical impeller, multi rotor to achieve large capacity, vertical single rotor structure, can meet the requirements of different products, high efficiency, low investment.

SKF Bearing

SKF bearing makes the transmission run more smoothly and stable.

High precision assembly

High precision assembly, the use of special shaft sleeve, labor-saving, reliable.

High energy efficiency

Air screen type secondary air design, high energy utilization, help material flow, improve the efficiency of powder separation.

Working Principle and Equipment type features

The classifier and cyclone separator, dust collector and induced draft fan form a classifying system.
Under the action of fan suction, the material is moved from the lower inlet of the classifier to the classifying zone with the ascending airflow. Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, the coarse particles entrained part of the fine particles collided with the wall and the velocity disappeared, descending along the cylinder wall to the secondary air outlet, and the coarse and fine particles were separated by the strong washing action of the secondary air. The fine particles rise to the classification zone for secondary classifying, and the coarse particles are lowered to the discharge port for discharging.
