The entire system consists of an air classifier, a cyclone collector, a pulse dust collector, a high-pressure induced draft fan, and an electric control cabinet. The air classifier is a forced-type classifier equipped with a large impeller rotor installed vertically and featuring secondary air intake. During operation, materials enter through the lower cylinder under the suction force of the induced draft fan. The primary external air fully mixes with the materials, allowing the particles to disperse thoroughly and rise to the classification zone. Due to the high-speed rotation of the classification impeller rotor, the particles are subjected to both the centrifugal force generated by the rotating impeller and the centripetal force produced by the suction of the induced draft fan. When the centrifugal force acting on the particles exceeds the centripetal force, coarse particles above the classification diameter are thrown toward the inner wall of the cylinder, lose speed, and slide down along the wall. The secondary external air enters through evenly distributed air inlets on the cone, creating an air-screening effect on the coarse particles to separate and clean the fine powder mixed or adhered to the coarse material. The separated coarse material is collected and discharged by the discharge device from the classifier. Fine particles below the classification diameter, along with the gas-solid two-phase flow, enter the cyclone collector and pulse dust collector for collection, while the purified gas is discharged by the induced draft fan.
Main Features:
1、The classifier structure has been specially designed to almost completely block all large particles, ensuring high classification accuracy and strict control over large particles.
2、The classification point can be freely adjusted through the rotational speed of the classifying impeller and the air volume of the induced draft fan to obtain the desired product, offering a wide classification range.
3、The vertical single-impeller classification structure with low rotational speed ensures a stable material flow field, resulting in high processing capacity and efficient classification.
4、A multi-stage series structure can be adopted to simultaneously classify several particle size segments, achieving an ideal particle size distribution.
