摘 要

传统旋风选粉机因分离效率低而影响粉磨产品的产量和质量，采用导流口可调式双出风口旋风分离器技术取代传统单出风口分离器对传统旋风选粉机改造后，降阻节能作用显著，分离效率明显提高，其提高部分恰是捕集细粉增加部分，因而产品细度改观，比表面积增大。产量也随之提高了。

Abstract

Tradition whirlwind powder selecting machine had low separation efficiency,it influence the output and quality of the powder products.Adopting water conservancy diversion mouth but the mode one pair of air outlets whirlwind separator technology replaced the tradition single air outlets separator.After transformated the tradition whirlwind powder slecting machine ,the reduce obstruction function was remarkable.The separation fficiency obvious improved.It was the lucky catch and collect thin powder of the adding.So the thin degree of the products changed,than the surface increased.The quality also improved.

Keyword:Whirlwind separator; Powder selecting machine;
