Shandong AlPa Powder Technology has laminated two years, successfully completed the special ceramic vertical grading wheel of lithium-electric positive electrode materials with a diameter of 600. Can be used with airflow classifiers. Compare the "ceramic horizontal grading wheel", successfully solved a series of problems such as adhesion, not fine, and unsteady. Shandong ALPA-developed lithium-eM positive material special ceramic vertical grading wheel can strictly control the iron content during operation, the grading is accurate, and the finished product is freely adjusted.In the field of processing of ultrafine powder, the airflow classifier is an important means of obtaining narrow particle size distribution and ultrafine particles. The grading wheel of the airflow classifier has the former flange, the post flange, the plurality of blades, the sealing plate composition, the blade and the front flange, the post flange is fixed, respectively, and an annular groove is opened on the sealing plate The rear end of the blade is inserted into the annular groove. There is a cavity between the adjacent blades, and the inner side of the plurality of blades form a cavity. The rear end portion of the blade has a radially large blade tail, and the rotating line speed of the blade tail is higher than the rotating line of the blade portion thereof, so the air flow formed by the rotation of the blade tail can block the powder outside the leaf tail, so that The material powder must be selected by the blade and the self-feed is in the discharge tube.
In the powder processing industry, it is often used to use the airflow classifier, the key components of the airflow classifier are their hierarchy impeller, when working, small materials from the rotating grade The gap between the blades of the impeller passes through, and the large material is blocked by the blade on the other to achieve the purpose of achieving material grading.
The material moves with rising airflow to the grading area under the fan pulleys, under the powerful centrifugal force generated by high speed rotation, the fine particles that meet the particle size required by the grading wheel into the cyclone and The dust collector is collected, and the crude particles drops to the pulverized region to continue to be pulverized.
The motor drives high speed rotation in the hierarchical housing (adjustable speed can be arbitrarily adjusted) to form a powerful centrifugal force in the airflow classifier. The gas powder mixture entered into the classifier first enters the interior. Under the action of centrifugation, the large or heavy particles are substantive force, so they are lying to the outer wall of the graded machine, and no longer suffering from the influence of the center. The lower fall to the crushing host to continue to smash or fall to the discharge port for collection; small or light material is small, in the internal hover, the impact of the wind turbine is brought to the height,To the next component is graded or collected. The size of the centrifugal force in the classifier can be adjusted by the variable frequency adjustment speed, and the purpose of the material that is divided into the specified particle size is reached. Currently, artificial intelligence and Internet of Things have been more and more fields, and AlPa Powder Technology is an industrial powder equipment manufacturer that has always adhered to technological innovation, in artificial intelligence and I have also explored the application of the Internet of Things.
