摘要
采用正交试验设计方法,分析了陶瓷粉料干法造粒机喷水时的转速、造粒时的延时转速以及喷头类型这三个因素对干法造粒中颗粒大小的影响。通过直观分析、方差分析和贡献率分析,结果一致表明,各因素对陶瓷粉料干法造粒颗粒大小影响显著性的大小顺序为:喷头类型>喷水转速>造粒延时转速;最佳因素组合方案为A1B1C1,即造粒机喷水时转速为60r/min、造粒机造粒时转速为60r/min、喷头类型为喷头1,按此工艺可得到较高的成品率,且该组合经济实用,工艺可行。
The effects of a dry granulator＇s rotation speed during spraying and granulation delay and its sprayer type on the particle size in dry granulation are analyzed by an orthogonal experimental method. Results of visual analysis, variance analysis and contribution rate analysis show that the influence of the three factors on particle size can be arranged in the following order of decreasing： sprayer type 〉 rotation speed during spraying 〉 rotation speed during granulation delay. A1B1C1 is the best combination scheme： rotation speed during spraying, 60 r/rain; rotation speed during granulation delay, 60 r/min; sprayer type, sprayer 1 .This process can get a high yield. It＇s also an economical and practical scheme
