摘　　要：采用三产品重介质旋流器中试试验平台对印度塔塔钢铁集团(Tata steel)的煤样进行分选试验,为选煤厂设计工作提供数据依据。通过对比和调整工艺参数,在保证精煤和中煤灰分达标的前提下,一、二段分选数量效率分别达到98.39%和97.98%,一段分选可能偏差为0.026 kg/L,二段分选可能偏差为0.039 kg/L。The experimental data of the tri-product heavy medium hydrocyclone in Tata Steel’s coal samples provide the basis for the design work.By comparing and adjusting the process parameters,the quantitative efficiency of the first and second stage separation reaches 98.39%and 97.98%respectively under the premise of ensuring the ash content of cleaned coal and medium coal reaching the standard.The possible deviation of the first stage separation is 0.026 kg/L,and the possible deviation of the second stage separation is 0.039 kg/L.
