工作原理：根據粉體顆粒大小、密度不同在干法狀態下進行分級。利用高速旋轉分級輪形成的離心力和氣流運動對粉體顆粒的推動力大小的不同，大或重的粉體顆粒受到的離心力大，遠離分級輪，至分級機邊壁自然下落；小或輕的粉體顆粒受離心力小，顆粒受氣流推動，進入分級輪，實現對物料的分級。

主要特點：

◆采用流體力學數值模擬軟件，計算出*合適的流場，*理想的壓力分布來指導設計，優化的分級葉輪結構，流場均勻穩定、葉輪壓力損失小，可對物料進行高效分級，分級效率達到70-93%；

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.
