Air lassifier Equipment

　　A variety of classification rotors are available, and the output can be adjusted; the speed of the wheel is controlled by the inverter, particle size can be adjusted freely. The classifying wheel can be made of ceramic materials, without metal pollution, meeting the requirements of high-purity materials.

　　Grinding is in a closed system, with little dust, low noise in a clean and environmentally friendly process.

　　In conjunction with ball mill, table roller mill, and Raymond mill to form closed circulation.

　　Optional explosion-proof design can also be upgraded to a nitrogen circulation system to meet the processing needs of flammable and explosive oxide materials.

Working Principle

Under the action of the fan, the material moves to the classification area at a high speed from the lower inlet of the classifier with the updraft. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the material is separated, and the fine particles meeting the particle size requirements enter the cyclone separator or dust collector through the blade gap of the classification wheel for collection. The velocity of some fine particles entrained by coarse particles disappears after hitting the wall and then decreases to the secondary air outlet along the wall of the cylinder. Through the strong washing effect of the secondary air, the coarse and fine particles are separated, the fine particles rise to the secondary classification in the classification area, and the coarse particles drop to the discharge port for discharge.
