working principle:
Air classifier is composed of feed inlet, adjustable air inlet, material dispersion area, classification area, and air outlet. A material disperser is set in the material dispersion area to fully disperse the materials entering the classifier to form a stable classification flow field to facilitate classification. The classification area is composed of a working chamber, a turbine-type classification wheel, and an electric motor. Wear-resistant treatment, the speed of the motor is controlled by the inverter to achieve the purpose of stepless speed regulation.
Technical advantages:
This model adopts a newly designed grading rotor, which can classify spherical, flake, and needle particles. The product size is infinitely adjustable, the classification efficiency is high, and the cutting point is accurate. Under the action of negative pressure wind and inertia force, the material enters the classifier from the feed port, and is fully dispersed under the action of the disperser in the material dispersion area. With the rising airflow, it enters the classification area. The "cage" turbine rotor controlled by the inverter High-speed rotation causes the material to generate centrifugal force. Under the relative balance of centrifugal force and air drag force, the separation of coarse and fine materials is achieved. The fine powder moves with the air through the "cage" turbine rotor to the discharge port and is collected by the collector. The coarse powder and agglomerated particles are dispersed again after encountering the secondary air flow during the falling process, and then discharged from the bottom after the second elutriation The material port is unloaded.
Application materials:
A multi-stage classification system is composed of multiple self-dividing classifiers in series, and is divided into several narrow particle size sections optimized for the size distribution of the material. The vertical single-rotor impeller and horizontal multi-rotor impeller are optimized for structural design and can be used with ball mills and other crushers The closed-circuit crushing and grading operation system makes the ultrafine powder processing equipment more reasonable and economical.
For flammable and explosive, oxidizable materials can be classified under the protection of inert gas.
It is widely used in chemical industry, minerals (classification of non-metallic mineral products such as calcium carbonate, kaolin, quartz, talc, mica), metallurgy, abrasives, ceramics, refractories, medicine, pesticides, food, new materials and other industries.
