我矿于1970年安装φ5.5×1.8米湿式自磨机9台。至1972年底陆续投产使用。多年的生产实践证明,自磨机衬铁的结构形式对自磨机生产能力和衬铁的使用寿命有很大的影响。投产初期,衬铁使用寿命很短,最长的为2个月左右;最短的只有20天左右,每台处理能力在50吨/时左右。 I mine installed φ5.5 × 1.8 meters wet self-grinding machine in 1970 9. By the end of 1972 have been put into operation. Years of production practice has proved that the structure of self-grinding iron liner structure of the self-mill production capacity and lining iron life has a great impact. Initial production, lining iron service life is very short, the longest for about 2 months; the shortest only about 20 days, each processing capacity of 50 tons / hour or so.
