The total wear of grinding media, during the cement clinker (balls of forging steel and hardened with 600 Brinell, and cylpebs by special iron) is of 162 – 308 g/t of cement (4.4 – 8.4 g/kWh) [2]. The presented values show a rapid wear of grinding media, which leads to the diminution of specific charge, with negative effects on grinding process. The throughput of the mill is reduced with 4 ...

Grinding aids are generally added to the ball mill to reduce electrostatic agglomeration of fine particles and to reduce coating formation on grinding media which reduces grinding efficiency. The optimum addition rate should be determined carefully to enhance grinding efficiency. Grinding aids also serve to reduce coating problems in cement storage and enhances cement strengths.

There is a strong correlation between the micro-structure and the wear rate of the media. Abstract . The paper initially focusses on developing a test procedure for measuring the wear of grinding balls and then correlating the results with the wear obtained in industrial scale cement ball milling applications. The cost of grinding media is one of the major items and it needs to be optimized by ...

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and ...
