无论是重介质旋流器还是重介质斜轮分选机,欲获得良好的洗选效果,都要求在悬浮液比重适宜、稳定的同时,入料量、供介压力和煤介比等主要条件也适宜、稳定。我厂没有设原料缓冲仓,又采用泵直接供介、配介,而且两台泵共用一条介质输送管道,因此,入料量、供介压力、煤介比等变化频繁,造成选后精煤灰分波动大,副产品含煤 Whether it is a heavy medium cyclone or a heavy medium oblique bevel sorter, to obtain a good washing result, it is required that the specific gravity of the suspension be suitable and stable, while the feeding conditions such as feed pressure, Also suitable, stable. I plant without raw material buffer warehouse, but also the pump directly for the media, with the media, and two pumps share a media pipeline, therefore, the amount of feed, for the pressure, coal ratio and other frequent changes, resulting in the election after the clean coal Large fluctuations in ash, coal by-products
