1) magnetic separation-screening
先磁后筛
2) screening and washing
先筛后洗
1.
The modification of screening and washing processes in Heda pulp mill included to change the existing order of screening and washing processes,put the washing prior to the screening;and also put the fine screening after the oxygen delignification;use the slot screen to take the place of the original hole screen and add more high consistency cleaners.
通过将筛选洗涤工艺流程由先筛后洗改造为先洗后筛,同时把精选段置于氧脱木素之后、孔筛换成缝筛,并增加高浓除渣器等技改措施,在漂白化学木浆生产线上把产量由180adt/d(风干)提高到230adt/d,漂后浆质量优于国家标准,筛选排污负荷大幅降低。
3) flotation and magnetic dressing
先浮后磁
1.
