摘要
基于正交试验法与响应曲面法,针对山西某铁矿磨矿产品中间易选粒级产率低的问题,通过单因素试验探究磨矿时间、磨矿浓度和介质充填率对中间易选粒级产率的影响规律,开展优化细磨中间粒级产率的试验研究。结果表明,采用正交试验法和响应曲面法得到的最优中间易选粒级产率分别为81.27%和81.80%。响应曲面法优化后得到的最佳磨矿条件为:磨矿时间14.15 min、磨矿浓度70.80%(质量分数)、充填率30.50%(体积分数),该条件优于正交试验法最佳条件,响应曲面法在分析因素之间交互作用对中间易选粒级产率的影响具有一定优势。研究明确了响应曲面法可充分实现提高磨矿产品中间易选粒级产率的目的,为相关厂矿同类问题提供可借鉴的方法。
Using the orthogonal test method and response surface method,aiming at the low yield of intermediate easy-to-selection grades of an iron ore grinding product in Shanxi,the single factor test was used to explore the effects of grinding time,grinding concentration and medium filling rate on the yield of intermediate easy-to-selection grades,and the experimental research on optimizing the yield of the fine grinding intermediate grain size was carried out.The results show that the optimal intermediate easy-to-selection grade yields obtained by the orthogonal test method and response surface method are 81.27%and 81.80%,respectively.The optimal grinding condition obtained after optimization by response surface method is as follows:grinding time 14.15 min,grinding concentration 70.80%(mass fraction)and the filling rate 30.50%(volume fraction).This condition is better than the best condition of orthogonal test method,and the response surface method has certain advantages in the influence of the interaction between the analysis factors on the yield of the intermediate easy-to-selection grade.The study clarifies that the response surface method can fully realize the purpose of increasing the yield of intermediate easy-to-selection grades of grinding products,and provide a reference method for similar problems in related factories and mines.
