a conventional ball mill circuit. The result: an increase in production of approximately 25 percent, and a reduction in specific power consumption of about 10 percent compared to a conventional ball mill system. Semi-finish grinding Upgrading a ball mill system with an HRP in a semi-finish mode is a simple solution, and installation is easy.
Apr 22, 2019· To achieve the specified grinding fineness, the workload of ball mill will be increased inevitably, and then, the energy consumption and power consumption will be increased accordingly.
Sep 05, 2015· Although it was developed nearly 50 years ago, Bond's method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding …
