重介旋流器是洗选难选煤的行之有效的一种方法,世界各国都有成熟的经验。我国自六十年代开始研制重介旋流器,并在设计中采用,也获得一定的成就,但在厂房布置上一般都是物料单独提升。悬浮液用泵打入入料定压漏斗中,与入料一起给入旋流器,物料的运输一般采用胶带输送机或斗式提升机提升。这两种方法都给 Dense medium hydrocyclone is a well-selected method of washing difficult coal, and all countries in the world have mature experience. Since the 1960s, China has developed the heavy-medium cyclone and adopted it in the design. It has also achieved some achievements. However, the general arrangement of the materials in the plant has been improved independently. Suspension pump into the feed pressure in the funnel, together with the feed into the cyclone, the general transport of materials using a belt conveyor or bucket elevator upgrade. Both methods are given
