Working principle: The machine is a vortex ultra-fine classifier, which is a centrifugal classifier with secondary air inlet and horizontal installation of rotor.Usually, the material and air (primary air) enter from the lower cylinder (which is characterized by convenient matching with the airflow mill of air conveying products, and there is no need to set up the raw material and airflow separation device) for pre dispersion. When the material rises to the periphery of the grading wheel, the qualified products are discharged from the upper part by the centrifugal force of the rotor, the coarse particles fall down, and are washed and screened by the secondary air in the air grid body, The fine powder in the coarse powder is further dispersed and dispersed again.An air seal isolation device is designed on the end face of the grading wheel to ensure that coarse particles are not mixed into the qualified products. At the same time, an air seal structure is installed at the bearing to ensure the normal operation of the bearing in a high dust environment.
Performance characteristics: 1 Wide classification range, high separation accuracy, high classification efficiency, single structure and small floor area;
2 It can be combined with mechanical crusher or pneumatic crusher for closed-loop operation, which can increase the effective production capacity;During closed-circuit operation, heat sensitive and low melting point materials are allowed to be crushed in the mechanical crusher.
Scope of application: As the machine is a dry air classifier, it is suitable for the classification of non stick materials and can classify spherical, flake and fibrous particles;It is suitable for chemical, mineral, building materials, electronics, pharmacy, pesticide, coating, dye, food, metallurgy, feed and other industries. It can dry grade all kinds of organic and inorganic substances.
