FXS雙出風(fēng)口籠形轉(zhuǎn)子選粉機的設(shè)計與改造
摘 要
傳統(tǒng)旋風(fēng)選粉機因分離效率低而影響粉磨產(chǎn)品的產(chǎn)量和質(zhì)量，采用導(dǎo)流口可調(diào)式雙出風(fēng)口旋風(fēng)分離器技術(shù)取代傳統(tǒng)單出風(fēng)口分離器對傳統(tǒng)旋風(fēng)選粉機改造后，降阻節(jié)能作用顯著，分離效率明顯提高，其提高部分恰是捕集細(xì)粉增加部分，因而產(chǎn)品細(xì)度改觀，比表面積增大。產(chǎn)量也隨之提高了。

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.
