分级效率高
颗粒空气分级技术研究进展 - University of Jinan
实验结果表明，当电动机频率达到42 Hz(此时分级室内风速接近大颗粒带出速度)，分级室上下布置反向冲击板时，分级效率最佳，最高分级效率约为80%。高回收率、高分级精度、采用气力分级 的方法 (1)分级前完全的分散状态； (2)分离作用力要强而有力，分离作用力 要只作用在点、线上，每个力的作用是 瞬间的，但整个作用区域 粉体工程之颗粒分级原理和技术 - 百度文库分级效率 (E)是指分级溢流中某一级别的重量与分级机给料中同一粒级重量的百分比。 它是考查分级机工作好坏的指标。分级效率 - 百度百科

分级效率指标常用者有：分级量效率；分级质效率；分级总效率； 分级修正效率以及修正效率的粒度值以相对粒度表示的分级折算效率等。 (1)分级量效率是某指定粒级在分级溢流 来讨论，不一定正确。. 下面的图，应该是想表达粉尘粒径越大，分级效率越高的意思，如果是同一类型的粉尘的话，感觉应该是平滑变化的趋势。. 上面的图，就直接画出了实验的 除尘器分级效率曲线怎样画？ - 知乎能效等级（Energy Efficiency Index）是表示家用电器产品能效高低的一种分级方法，根据国家的相关标准规定， 中国的能效标识将能源效率分为五个等级。 能效标准与能效标识已 能效等级 - 百度百科

水力旋流器，是利用离心力来加速矿粒沉降的分级设备。它需要压力给矿，故消耗动力大，但占地面积小、价格便宜，处理量大，分级效率高，可获得很细的溢流产品，多用于第二段闭路磨矿中的分级设备。CN104307749A CN201410531484.2A CN201410531484A CN104307749A CN 104307749 A CN104307749 A CN 104307749A CN 201410531484 A CN201410531484 A CN 201410531484A CN 104307749 A CN104307749 A CN 104307749A Authority CN China Prior art keywords screen cloth fixed rotating shaft preliminary classification rack Prior art CN104307749A - 一种手摇式茶叶分级装置 - Google PatentsCN104307749B CN201410531484.2A CN201410531484A CN104307749B CN 104307749 B CN104307749 B CN 104307749B CN 201410531484 A CN201410531484 A CN 201410531484A CN 104307749 B CN104307749 B CN 104307749B Authority CN China Prior art keywords screen cloth rotating shaft preliminary classification rack fixed Prior art CN104307749B - 一种手摇式茶叶分级装置 - Google Patents
