7 advantages of air classifier

The classifier, cyclone separator, dust collector and induced draft fan form a classifying system. Under the action of fan suction, the material moves to the classification area at high speed from the inlet at the lower end of the classifier along with the updraft, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating classifying turbine.

The fine particles that meet the particle size requirements enter the cyclone separator or dust collector through the gap between the blades of the classifying wheel to collect. The coarse particles entrain some fine particles and the speed disappears after hitting the wall, and drop down to the secondary air outlet along the cylinder wall. The washing effect separates the coarse and fine particles, the fine particles rise to the classification area for secondary classification, and the coarse particles descend to the discharge port for discharge.

The air classifier, cyclone separator, dust collector and induced draft fan form a complete crushing system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber through the Laval nozzle at high speed, at the intersection of multiple high-pressure airflows.

The materials are repeatedly collided, rubbed, sheared and crushed. The crushed materials are moved to the classification area with the upward airflow under the action of the fan suction. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated to meet the particle size The required fine particles enter the cyclone separator and dust collector through the classification wheel to collect, and the coarse particles descend to the crushing area to continue crushing.

The seven advantages of the air classifier are as follows:

●Airflow classifier is suitable for dry crushing of various materials with Mohs hardness below 9, especially for high hardness, high purity and high value-added materials.

●The airflow classifier contains a horizontal classifying device, the top cutting is accurate, the product particle size D97: 2-45 microns is adjustable, the particle shape is good, and the particle size distribution is narrow.

●Low temperature and medium-free crushing, especially suitable for crushing heat-sensitive, low-melting, sugar-containing and volatile materials.

●The crushing process is mainly completed by the collision between the materials themselves, which is different from mechanical crushing which relies on the impact crushing of the materials by blades or hammers, so the equipment is wear-resistant and the product purity is high.

●The equipment is easy to disassemble and clean, and the inner wall is smooth without dead ends.

●The whole system is sealed and crushed, with less dust and low noise, and the production process is clean and environmentally friendly.

●The control system of the air classifier adopts program control, which is easy to operate.
