工作原理：根據(jù)粉體顆粒大小、密度不同在干法狀態(tài)下進(jìn)行分級(jí)。利用高速旋轉(zhuǎn)分級(jí)輪形成的離心力和氣流運(yùn)動(dòng)對(duì)粉體顆粒的推動(dòng)力大小的不同，大或重的粉體顆粒受到的離心力大，遠(yuǎn)離分級(jí)輪，至分級(jí)機(jī)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(dòng)，進(jìn)入分級(jí)輪，實(shí)現(xiàn)對(duì)物料的分級(jí)。
主要特點(diǎn)：
◆采用流體力學(xué)數(shù)值模擬軟件，計(jì)算出*合適的流場(chǎng)，*理想的壓力分布來(lái)指導(dǎo)設(shè)計(jì)，優(yōu)化的分級(jí)葉輪結(jié)構(gòu)，流場(chǎng)均勻穩(wěn)定、葉輪壓力損失小，可對(duì)物料進(jìn)行高效分級(jí)，分級(jí)效率達(dá)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.
