High-precision efficiency of airflow classifiers come from its special advantage characteristics

　　ALPA gas flow grinding closed negative pressure, low temperature crushing, high purity operation, no dust pollution, system discharge is less than 5 mg / m3. The pulverized chamber is equipped with an automatic slag device that automatically eliminates difficult particles and impurities in the material. The reunion material has a dispersion and dispersion. The air of the large flow means that cooling polishing can be used for thermal material processing, no deposition. Automation control, low noise, no dust pollution.The airflow classifier can be used separately, and can also be used in series with pulverization equipment such as airflow pulverizer, mechanical pulverizer, ball mill, vibration grinding, and produce a finished product with a particle size. The application range of airflow classifiers is wide. It is currently universal in the fields of ore, chemical, polymer materials, new materials, battery materials, rare earth polishing powders.

　　Airflow classifier is a set of grading systems for airflow classification equipment, grading machine and cyclone separator, dust collector, and airformat. The material is moved from the lower airflow at the lower airflow at the lower airflow at the bottom of the strata, and the crude material is separated, and the fine particles required by the particle size are separated, and fine particles required for the particle diameter requirements are graded by fractionation. The wheel blade gap is collected into the cyclone separator or the dust collector. The thickness of the crude particles is partially disappeared. The roughness of the secondary wind is removed, and the thickness of the thickness is separated, fine The particles rise to the secondary grade of the graded area, and the crude particles are dropped to the unloading port.

　　The structural characteristics are as follows:

　　(1) The injection of the fine granules under high speed rotary impeller, and the gas pressure flowing through the impeller is raised, and after the high pressure airflow flows out of the impeller, after injection of the fine granules, due to the rotation of the air The blade of the leaf is designed to be curved, large, and the export is small, so the airflow pressure of the outlet is lowered, the speed is increased, and the rotten flow is conducive to the grading.

　　(2) The hierarchical point adjustment mechanism sets three adjustment rods and keeps it synchronous with the chain. The adjustment rod moves upward, the fine powder is increased; the adjustment rod moves downward, the fine powder is reduced. The grading point may be adjusted continuously, and the performance of the Erfai airflow classifier product particle size is adjustable. The gradular products can reach D97: 3 ~ 150 microns, suitable for fine grading of dry micron products.

　　(3) The control ring is provided with a control ring to ensure the formation of a suitable cross section between the control ring and the injection fine granules, and the airflow flow rate is stabilized.

　　(4) The remaining wind port is inevitable from the dry material to bring the excess gas, and the level of temperature is high, and the air will expand, so it is designed to maintain stability and balance between the graded indoor airflow. [2] The performance characteristics are as follows:

　　1. Suitable for fine grading, graded spherical, sheet-like, and irregular shaped particles, can be graded for different density particles.

　　2. The grade grade of grading can reach D97: 3 ~ 150 microns, and the product particle size is not adjustable, and the variety replacement is extremely convenient.

　　3. The grading efficiency (extraction rate) is 60% to 90%, the grading efficiency is related to the material properties and the particle size of the particle size. The particle content of the material is good, the particle size requirements are high, the efficiency is high, and the effect is low. .

　　4. The hierarchical rotation speed is high and the vertex cut is accurate.

　　5. Multi-level classification machines are used in series, while producing multiple particle size sections.

　　6. Can be used in series with polishing equipment such as ball mill, vibration grinding, Raymond mill, constitutes a closed circuit loop.

　　7. The control system uses program control, and the operation status is displayed in real time, and the operation is easy.

　　8. The system is negative pressure, and the dust emissions are 40mg / m. After silence measures, the equipment operates noise is not higher than 75dB (a).

　　Airflow classifier is one of the main products of Shandong Er, El Pie has been divided into 3 years in the grading, and in the field of crushing. It is more dealing with domestic manufacturers in the grading accuracy. In many users, they have been enthusiastic in many users. Those who believe that Shandong Erfai airflow classifier is accurate, and the equipment is stable.

　　In terms of quality inspection, ALPA powder technology is particularly stricter. It is well known that a manufacturing process of a ultrafine powder is often up to hundreds. As a special equipment, the airflow pulverizer is like a special process, and it is possible to make a big disaster. Therefore, ALPA powder technology has established seven process stop points in the production process, which is strictly controlled by different engineers, and each other is independent and mutual supervision, and it is timely discovery and solve the problem. Any detail is unqualified, it is unable to enter the proceeding process, which is the quality monitoring of AlPa powder technology to the production process.
