Horizontal airflow classifier

1. Working principle

The classifier, cyclone collector, pulse dust collector, induced draft fan, and control cabinet form a classification system. Under the suction force of the fan, the material moves at high speed from the inlet of the classifier to the classification zone along with the rising airflow. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the powder mixed in the gas-solid two-phase fluid is separated according to particle size. Fine particles that meet the particle size requirements pass through the gap between the classification wheel blades and enter the cyclone separator or dust collector for collection. Materials that do not meet the particle size requirements carry some fine particles, which fall along the cylinder wall to the secondary air outlet under the action of centrifugal force and wall stall. The strong washing effect of the secondary air separates coarse and fine particles, and the fine particles rise to the secondary classification zone for secondary classification. The coarse particles fall to the discharge port and are discharged.
