摘要
实验测定了铁粉和钛粉(Fe-Ti)、铁粉和三氧化二铝粉(Fe-Al2O3)、铁粉和铝粉(Fe-Al)3种二组元粉末体系在圆筒型混合器中混合过程的均匀度。研究结果表明:粉末物性的差别对混合效果产生明显的影响,当填充率和转速相同时,不同物性的二组元粉末体系的混合运动状况不尽相同,混合均匀度表现出明显的差异。在50s内,流动性较好的AlO3粉和Al粉分别与Fe粉较均匀地混合;而流动性较差的Ti粉与Fe粉没有有效地混合。Fe-Ti体系、Fe-Al体系和Fe-Al2O3体系的最终混合均匀度分别为0.275,0.048和0.025。
The experiment has carried on the mixing of three kinds of two-component different characteristics of powder in a rotating drum blender. The results show that the characteristic of powder has great influence on the efficiency of mixing. The results show that the more similar of the physics characteristics of the mixing powder, the better of mixing performance. The Fe- Al2O3 and Fe-Al are mixed well in 50 s, but Fe-Ti are not mixed well. The last deviation of Fe- AlO , Fe-Al and Fe-Ti are 0. 275, 0. 048 and 0. 025, respectively.
