我们的研究目的是应用Box-Behnken实验设计和响应面方法对一些土耳其煤进行建模。作为本研究的基础，首先进行了标准Bond可磨性试验，并计算了3种土耳其煤的Bond功指数（W-i）值。采用Box-Behnken实验设计为建模提供数据，模型变量为Bond功指数、磨矿时间和磨球直径。对三种煤级（-3350 + 1700 μ m， -1700 + 710 μ m和-710 μ m）进行了改变这三个变量的磨煤试验。利用数学软件包（MATLAB 7.1）获得的这些实验数据集，建立数学模型，显示各参数及其相互作用对产品80%通过尺寸（d(80)）的影响。利用模型方程得到的d（80）预测值与d（80）的实验值（-3350 + 1700亩m的R-2值为0.96，-1700 + 710亩m的R-2值为0.98，-710亩m的R-2值为0.94）吻合较好。该研究证明Box-Behnken设计和响应面方法可以有效地应用于某些土耳其煤的磨矿模拟。(c) 2006 Elsevier Ltd.版权所有。
The aim of our research was to apply Box-Behnken experimental design and response surface methodology for modeling of some Turkish coals. As a base for this study, standard Bond grindability tests were initially done and Bond work indexes (W-i) values were calculated for three Turkish coals. The Box-Behnken experimental design was used to provide data for modeling and the variables of model were Bond work index, grinding time and ball diameter of mill. Coal grinding tests were performed changing these three variables for three size fractions of coals (-3350 + 1700 mu m, -1700 + 710 mu m and -710 mu m).Using these sets of experimental data obtained by mathematical software package (MATLAB 7.1), mathematical models were then developed to show the effect of each parameter and their interactions on product 80% passing size (d(80)). Predicted values of d(80) obtained using model equations were in good agreement with the experimental values of d(80) (R-2 value of 0.96 for -3350 + 1700 mu m, R-2 value of 0.98 for -1700 + 710 mu m and R-2 value of 0.94 for -710 mu m). This study proved that Box-Behnken design and response surface methodology could efficiently be applied for modeling of grinding of some Turkish coals. (c) 2006 Elsevier Ltd. All rights reserved.
