扩大和提高工艺设备的生产能力,是现代选矿技术发展的一种趋势。在国外很多新建的有色金属选矿厂中,已经有效地使用了一些大型球磨机(直径从4.72米到5.49米)。这些磨机的有效容积为85米。～154米0,电动机功率为1860～3350千瓦。在有些黑色金属选矿厂已开始采用直径大于5米,容积为200～250米~3和电动机功率为4620～5150千瓦的球磨机。使用大型球磨机可使其安装台数大为减少,(一般每个选矿厂都在两台以上)。这样就能大大减少投资费用和降低磨矿成本,提高磨
To expand and improve the production capacity of process equipment is a trend of the development of modern dressing technology. Among many new foreign non-ferrous metal concentrators, some large ball mills (diameter from 4.72 to 5.49 meters) have been effectively used. The effective volume of these mills is 85 meters. ~ 154 meters 0, the motor power is 1860 ~ 3350 kilowatts. In some ferrous metal concentrators, ball mills with a diameter of more than 5 meters and a capacity of 200-250 m 3 and a motor power of 4620-515 kW have been used. The use of large ball mill can greatly reduce the number of its installation (usually each concentrator in more than two). This will greatly reduce investment costs and reduce grinding costs and improve the mill
