摘　　要：分析探讨了散料颗粒风力分级的基本原理 ,提出并设计了一种新型的散料颗粒离心式风力分级设备 ,提出了完整的颗粒分级工艺。该技术具有处理能力大、分级效率较高、能耗低和操作方便等特点 ,特别适用于不宜筛分的大宗散料颗粒的分级。实验结果表明 ,该技术用于尿素脱除细粒粉料 ,可以达到良好的分级效果。Based on the analysis to the principle of the pneumatic classification for the powder materials, a new type of centrifugal pneumatic classifier for urea product has been developed. A new technological process of classification has been also proposed for the industrial application. The experimental results show that the new classifier combined with the new process can reach a satisfactory efficiency in the classification of urea product in a large scale of capacity.
