**Product Introduction:**

The entire classification system consists of an airflow classifier, a cyclone collector, a pulse dust collector, a high-pressure induced draft fan, and an electrical control cabinet. The airflow classifier is a forced-type classifier with a large impeller, featuring secondary air intake and vertical installation. During operation, under the suction force of the induced draft fan, the material enters from the lower cylinder and rises to the classification zone. Due to the high-speed rotation of the classification impeller rotor, particles are subjected to both the centrifugal force generated by the rotation of the classification impeller and the centripetal force produced by the induced draft fan. When the centrifugal force acting on a particle exceeds the centripetal force, coarse particles above the classification diameter are thrown to the inner wall of the cylinder, lose speed, and slide down along the wall. External secondary air enters through evenly distributed air inlets on the cone, creating an air-screening effect on the coarse particles to separate fine powders mixed or adhered to the coarse material. The separated coarse material is collected and discharged from the classifier via a discharge device. Fine particles below the classification diameter, along with the gas-solid two-phase flow, enter the cyclone collector and pulse dust collector for collection. The purified gas is then discharged by the induced draft fan.

Highlighted Advantages:

1. The interior of the classifier is lined with ceramic protection, resulting in minimal equipment wear, no product contamination, and high purity.

2. The classifier structure has been specially designed to block all large particles, ensuring high classification accuracy and strict control over large particles. The classification point can be freely adjusted through the rotational speed of the classification impeller and the airflow 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, high processing capacity, and excellent classification efficiency.

4. A multi-stage series structure can be adopted to simultaneously classify products into several particle size segments, achieving an ideal particle size distribution.

5. Customized graded impellers can be made based on different materials from the customer, ensuring high purity and no contamination.

When the centrifugal force acting on a particle 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. External secondary air enters through evenly distributed air inlets on the cone, creating an air-screening effect on the coarse particles to separate fine powders mixed or adhered to the coarse material.
