工作原理：根据粉体颗粒大小、密度不同在干法状态下进行分级。利用高速旋转分级轮形成的离心力和气流运动对粉体颗粒的推动力大小的不同,大或重的粉体颗粒受到的离心力大,远离分级轮,至分级机边壁自然下落；小或轻的粉体颗粒受离心力小,颗粒受气流推动,进入分级轮,实现对物料的分级。

Working principle: Depending on particles' size and density under dry-type for grading, it uses the centrifugal force produced by the fast rotation of grading rotator together with flow movement to perform classifying, the coarser particles above the grading rang is drove by centrifugal force will be swirled down along the container wall, and finer grains bring to the grinding zone.
1.Fluid dynamics software is developed by our independent R&D, calculated the perfect flow and ideal pressure distribution, is used for high efficiency grading, the grading rate is up to 70%~93%.
2.Dispersion device and turbulent device ensure high efficiency grading.
3.Aggregated powder is resolved by optimization structure .
4.The outer face end seal technology(unique technology) ensures no coarser particles leak.
5.Secondary air entry keeps the cleaning flow stability, greatly reduce the wear
6.Omniseal negative pressure operation, no contamination.
