利用煤与煤系硫化物的磁化系数不同,并对煤中黄铁矿的磁性强化,探讨用磁选法对煤系硫化物进行分选的方法,设计一个磁选机,既有较高的磁场强度又有磁场梯度,以达到除掉煤中黄铁矿硫的目的。
Using different magnetization coefficients of coal and coal-based sulfide, and magnetic strengthening of pyrite in coal, a method of separating coal-based sulfide by magnetic separation is discussed. A magnetic separator is designed, Magnetic field strength and magnetic gradient, in order to achieve the purpose of removing pyrite sulfur in coal.
