The working principle and characteristics of air classifier

Working principle of air classifier:

The classifier, cyclone separator, dust collector and induced draft fan constitute a classification scheme. Under the action of the fan force, the material moves from the lower inlet of the classifier to the classification area at high speed. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, and the fine particles meeting the particle size requirements are collected into the cyclone separator or dust collector through the blade gap of the classification wheel. After the coarse particles and fine particles hit the wall, the velocity disappears and decreases along the wall to the outlet of the secondary air. Through the strong scouring effect of the secondary air, the coarse particles and fine particles are separated. The fine particles rise to the secondary classification area and the coarse particles fall to the outlet.

Features of air classifier:

1. Large output, low energy consumption and high efficiency of hierarchical management.

2. Particle concentration: original classification of vertical impeller for machine use. Stable classification technology and special sealing measures can effectively prevent the leakage of coarse particles, so that the product does not have large grains, particle size concentration and high classification accuracy.

3. Reasonable structure: according to the requirements of users, we can produce 1-6 granularity products at the same time.

4. Applicability: it can be combined with various mills (air mill, mechanical mill, ball mill, regrinding mill, vibration mill, etc.) Form closed circuit or open circuit combined operation.

5. High degree of automation: electronic frequency modulation stepless speed regulation is adopted in each stage of impeller classifier, which realizes electronic control in the process of automatic circulation multi box dust removal, realizes automatic dust cleaning, and improves the stability of negative pressure of the whole machine.
