一、重力选煤过程模拟的研究概况采用电子计算机预测重力选煤过程,要进行重选过程的模拟。利用重选模型可计算产品的数量和质量,选择最优工作制度和分选指标,从而取得较大经济效益。重选模拟的基础是利用原煤的浮沉试验结果,按照产品分配率对过程进行预测计算。实质上,这种预测计算和传统的重 First, the gravity coal preparation process simulation study Overview The use of computerized gravity coal preparation process, to be re-election process simulation. Using reselection model can calculate the quantity and quality of products, select the optimal working system and sorting index, so as to obtain greater economic benefits. Re-election simulation is based on the use of raw coal flotation test results, in accordance with the product distribution rate of the process of predicting the calculation. In essence, this predictive calculation and traditional weight
