Air classifier, multi-stage series classification equipment, multi-unit classifier system

Working Principle:

The classifier, dust collector, and induced draft fan form a classification system. Under the suction force of the fan, the material enters from the lower end of the classifier.The material opening rises accordingly.The airflow moves at high speed to the classification zone, where the strong centrifugal force generated by the high-speed rotating classification vortex separates coarse and fine materials. Fine particles meeting the required particle size pass through the gaps between the classification wheel blades and are collected by a cyclone separator or dust collector. Coarse particles, carrying some fine particles, lose their velocity upon colliding with the wall and descend along the cylinder wall to the secondary air inlet. There, the strong washing action of the secondary air separates the coarse and fine particles. The fine particles rise to the classification zone for secondary classification, while the coarse particles descend to the discharge port for removal.

Performance Features:

1. Using a completely dry production process without water or washing, it is possible to obtain abrasive micro-powders with a narrower particle size distribution and no contamination; onceHierarchicalProcessed into any grade according to current domestic and international standards.OneProducts with grade designations (e.g., national standard W63～W3.5, Japanese standard 240#～3000#, and European standard F230/53～F1200/3). The yield rate for individual grades exceeds 75%.

2. High classification precision, more accurate cut particle size, lower required rotational speed, and long service life.

3. Independent cast bearing housing, resistant to deformation, with a long service life.

4. Optimized transmission design ensures low bearing stress and long service life.

5. Unique pipeline design facilitates powder flow, reduces wear, and makes wear-prone areas easy to replace and maintain.

6. The company's unique variable frequency feeding system facilitates material dispersion, ensures continuous, uniform, and stable feeding, and aids in product particle size control.

7. Unique internal circulation secondary air design, stagedIntervertebral spaceAdjustable, significantly reducing gas consumption, thereby lowering classification energy consumption and ensuring thorough extraction of fine powder.

8. The separation of flow paths helps reduce wear at the bottom of the classification wheel and is more conducive to controlling larger particles.

9. Fully enclosed negative pressure operation, no dust pollution.

10. Good stability: once the fixed parameters are adjusted, stable production can be maintained.

11. In particular, the core advantages of more thorough extraction of fine powders and good stabilityIt seems like you meant "竞争" (competition). Here is the English translation: **Competition**The advantage has been widely recognized by the industry.

12. The entire system adopts automated control, enablingOne-button start/stopThe operation is simple and convenient, and it can achieve remote control when connected to the central control system.

◆ General Applications:
The ZJ-F series precision airflow classifiers are capable of classifying materials that cannot be processed on conventional sorting equipment, making them particularly suitable for handling strict**Restrictions**Products that require particles and a narrow particle size distribution, such as ground calcium carbonate, kaolin, talc powder, barite powder, copier toner, coatings, mica, graphite, auxin, aluminum hydroxide, etc.

◆ High-purity applications:
The ZJ-F series precision airflow classifier is suitable for materials with extremely strict requirements on impurity content or materials that are highly sensitive to iron contamination.It simultaneously meets the requirements for particle size and particle size distribution. Typical materials include: phosphor powder, titanium dioxide, starch, silica gel, aluminum, copper, luminescent powder, and various high-purity pigments.

◆ Abrasives and hard materials:
The ZJ-F series precision airflow classifier can perform ultra-fine classification of hard materials with a Mohs hardness of 7 or above. The application of the vertical vortex classifier enables the equipment toSeverely worn.Small. The rotational speed of the classifier wheel is adjustable, and the crushing parameters can be optimized and selected. When multiple classifiers are combined, narrow-band classification across several particle size ranges can be completed in a single pass. Typical products include: diamond, silicon carbide, boron carbide, tungsten carbide, special ceramics, emery, etc.

◆ Food, Health Products, and Pharmaceuticals:
The ZJ-F series precision airflow classifiers are capable of ultra-fine processing of pharmaceuticals, food, and health products. Their low-temperature grinding, high-purity operation, high processing smoothness, and easy-to-clean features make the ZJ-F series ideal for use in the pharmaceutical, health product, and food industries. These characteristics not only enhance the bioavailability and efficacy of drugs but also reduce production costs. Typical products include pollen, hawthorn, shiitake mushrooms, pearl powder, stomach medications, nimodipine, antibiotic drugs, contrast agents, reishi mushrooms, Chinese gallnuts, and fleeceflower root.

◆ Other industries:
The ZJ-F series precision airflow classifiers can operate in a closed-loop system with inert gases to classify materials that are highly prone to combustion, oxidation, or explosion, such as carbonyl iron powder and nickel powder.Tungsten-cobalt alloy powderselenium powder, etc.
