首钢水厂选厂的砂石破碎,设计采用粗、中、细三段—闭路流程。随着细筛再磨自循环和磁滑轮甩尾等工艺的采用,1983年铁精矿品位由63％上升至68.5％,但球磨机的处理能力随之下降。因此,水厂矿采取了降低入磨粒度的方法提高磨机台时能 Shougang plant water treatment plant crushed gravel, the design of coarse, medium and small sections - closed circuit flow. With fine sieve regrinding and magnetic pulley tailing and other processes used in 1983 iron concentrate grade increased from 63% to 68.5%, but the ball mill’s handling capacity decreased. Therefore, the water mill mine has taken to reduce the size of the grinding method to improve mill when the table
