防止空气污染的规定日趋严格,而开采煤层的硫分不断上升,因此,为降低煤炭硫分就需要做出更大的努力。一般熟悉的方法是通过机械途径分离以黄铁矿形式出现的无机硫。粉煤跳汰机为在黄铁矿充分解离的粒度范围内通过机械方法脱硫提供了可能,另外改善总回收 Regulations to prevent air pollution are becoming stricter and the sulfur content of the coal seams is continuously rising. Therefore, more efforts are needed to reduce the sulfur content of coal. A commonly known method is the mechanical separation of inorganic sulfur in the form of pyrite. Pulverized coal jig offers the possibility of desulfurization by mechanical means within the range of particle size that is sufficiently dissociated by pyrite and additionally improves the total recovery
