For ball mills, wear and tear of the lifting bars is the main causes of failure of the liner of the ball mill. According to historical data, wet ball mills consumed more than 110,000 tons of liners in metal mines during 2004 in China. However, green environmental protection is the mainstream trend of world economic development, which adds new ...
EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
