Palladium, rhodium, ruthenium and palladium–copper SACs were all produced using the ballmilling process. ''We estimate that with our strategy, the preparation cost of noble metal SACs is less than (£) per gram,'' says Ma. He adds that this shows ''great promise for commercial applications'' once the process is optimised further.
The paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills. Basic kinetic and energy models of the grinding process are described and the most commonly used control strategies are analyzed and discussed.
