回转窑物料停留时间实测方法探索

Discussion on Real Time Measurement on Retention Time of a Charge in Rotary Kilm

通过分析有色冶金工厂回转窑物料停留时间τ的经验计算公式及其影响因素 ,结合云锡公司个旧冶炼厂1.0 m× 13 m回转窑还原焙烧低品位结合氧化矿的生产实践 ,初步探索出窑内存料法和初排料法两种实测 τ值的方法 ,并详细介绍了这两种方法的实测过程及结果分析。

By analyzing empirical calculation formula of retention time( τ ) of a charge in non ferrous metallurgical rotary kiln and influence factors, on the basis of the production practice of reduction roasting of low grade oxidized ore in φ1 0 m×13 m rotary kiln in Gejiu Smelter, the two kinds of real time measurement have been researched out primarily, the procedure and result analysis of two kinds of real time measurement τ value also has been introduced.
