摘　　要：介绍了高梯度磁选分离技术用于原煤脱硫的技术原理,并利用高梯度磁选机进行了不同煤种的湿法和干法高梯度磁选脱硫试验。通过正交试验,确定了利用高梯度磁选机进行原煤湿法磁选脱硫、脱灰的最佳试验条件,试验结果显示,湿法和干法磁选脱硫的脱硫效率分别达到50%和35%以上,煤的粒度越细脱硫效果越好。This author introduced the technique of high gradient magnetic separation splitting technique, and took different kind fine grain coal doing wet and dry methods of desulfurization test with the high gradient magnetic separation machine. By means of crosstab test, it makes certain the optimumtest term with raw coal wet method magnetic separation desulfurization and dedustering. This result shows that efficiency of wet and dry methods of desulfurization are beyond 50 and 35 per cent separately. The slender of the size of coal, the better desulfurization effect.
