Airflow Grading Machine Working Principle
High-speed rotating classification wheels generate a strong centrifugal field at the outer edge of the wheels. Larger micron-sized particles are ejected due to greater centrifugal force, while smaller micron-sized particles, with less centrifugal force, are blown away by wind.The "inhalation"分级轮 is internally processed and, after passing through the fine powder chamber and conveying pipeline, the material is collected in the collector.
An air classification machine must be integrated with a collector, induced draft fan, discharge valve, and feeding machine to complete the classification process. It can be combined with ball mills, Raymond mills, roller presses, vertical mills, and other pulverizing equipment to form a closed-loop or open-loop production system.
Application Fields
Ideal for grading the particle sizes of irregularly shaped granules like spherical, flake, needle, etc., separating two materials of different densities, and removing impurities from powdered materials.
Widely used in industries such as chemicals, non-metallic minerals, metal ores, abrasives, ceramics, refractory materials, food, and new materials.
FWN Airflow Grading Machine Advantages:
l New Grading Machine：Than traditionalThe FW horizontal grading machine features a more rational structure, utilizing belt drive and a new grading wheel design.
l Low energy consumption:Lower than traditional vertical and horizontal graders15～50%
l High efficiency:Utilizing the innovative self-leveling technology and pre-dispersed structure, the grading efficiency surpasses traditional vertical,Horizontal grading machine with a height increase of 25-50%
l High resolution:High granulation up toD97 2 microns, product particle size is adjustable, and it's relatively easy to change varieties.
l High precision:New gap seal structure, eliminating adhesion effect, preventing large particles and screenings.
l Environmental Protection:The system operates under negative pressure, ensuring the production process fully complies with the country's high environmental protection standards and achieves dust-free production.
l Low maintenance costs:New graded wheel, production Mohs hardness less thanAt 5 Mohs, no wear occurs. When producing materials with a Mohs hardness greater than 5, the lifespan is improved by 3-8 times compared to traditional vertical and horizontal classifiers.
