摘　　要：新一代N-U型选粉机采用了一种全新的动叶片设计形式,通过调节外风翅角度,可适应不同成品细度要求,有效控制成品的粒度分布。N-U型选粉机动叶片呈U型设计,拉拽力作用效果增强,在保证选粉效率不变的情况下,可有效降低选粉机通风阻力。改造后,磨机喂料量提升10.0%以上,生料粉磨系统电耗降低约1.0kW·h/t,投资回收期仅一年左右,改造效果显著。The new generation of N-U classifier adopts a new design shape of rotor blade,which can meet the fineness requirements of different products by changing the blade angle,and the particle distribution of products can be effectively controlled.Because the separator's rotor blade is U-shaped,and pulling force is stronger,the classifier can reduce the pressure of classifier under the same level classifier efficiency.After modification,the feed rate increase by about 10.0%,the system power consumption of raw mill decrease by about 1.0 kW·h/t,the payback period is only one year,and the modification effect is remarkable.
