Performance advantages of metal powder air classifier

Metal powder airflow classifiers are widely used in ore dressing plants. They are combined with ball mills to form a closed loop and split-flow ore sand, or used in gravity concentrators to classify ore and fine mud, and to classify ore slurry and wash ore in the metal beneficiation process. Desliming, dewatering and other operations in operation. The machine has the characteristics of simple structure, reliable work and convenient operation.

The metal powder air classifier is a kind of air classifier. The classifier, cyclone separator, dust collector and induced draft fan form a set of classification system. Under the action of fan suction, the material moves to the classification area at high speed from the lower inlet of the classifier along with the updraft. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, and the fine particles that meet the particle size requirements are classified. The gap between the wheel blades enters the cyclone separator or the dust collector to collect, the coarse particles entrained by the part of the fine particles hit the wall and the speed disappears, and they descend along the cylinder wall to the secondary air outlet. After the strong elutriation of the secondary air, the coarse and fine particles are separated. The particles rise to the classification zone for secondary classification, and the coarse particles fall to the discharge port for discharge.

Performance advantages and characteristics of metal powder air classifier:

The metal powder airflow classifier is a perfect combination of self-split inertial classification technology and centrifugal classification technology. Its core technology has reached the world’s advanced level, and its technical performance is greatly improved compared to turbo classifiers.

1. Low energy consumption: the same processing capacity, energy consumption is 50% lower than other horizontal and vertical classifiers.
2. High efficiency: the same processing capacity, the classification efficiency is 50% higher than other horizontal and vertical classifiers.
3. High precision: high grading fineness, completely eliminates oversized particles and sieve residues in the product.
4. Low rotation speed: the rotation speed of the classification wheel is 50% lower than other horizontal and vertical classifiers for the same classification particle size. When producing powder with a Mohs hardness of 5, the grading wheel has no wear; when producing powders with a Mohs hardness ≥ 7, the service life of the grading wheel is 5 to 8 times longer than that of other horizontal and vertical types.
5. High output: the output of mainframe can reach 50t/h.
6. Reasonable structure: a dedicated hierarchical structure can be configured according to different special requirements.
7. It can be combined with ball mill, Raymond mill, impact mill, jet mill and other grinding equipment to form a closed circuit or open circuit system.
8. Negative pressure production, no dust pollution, excellent environment.
9. High degree of automation, strong stability and easy operation. All impeller classifiers at all levels adopt electronic frequency modulation and stepless speed regulation. Electronic control and automatic dust removal are realized in the automatic circulation multi-box dust collection process, which improves the stability of the negative pressure of the whole machine.
